Huly MCP

Add a file to an inventory product resolved by product ID or exact name. Provide exactly one source: filePath is resolved on the MCP server host, data is client-local base64 content, and fileUrl is fetched by the MCP server.

Add a Markdown comment directly to an inventory product resolved by product ID or exact name. Pass category to disambiguate duplicate names. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Add a photo to an inventory product using Huly's product photos collection. Provide exactly one source: filePath is resolved on the MCP server host, data is client-local base64 content, and fileUrl is fetched by the MCP server.

Add an attachment to a Huly issue resolved by project and identifier. Provide one source: filePath is resolved on the MCP server host, data is client-local base64 content, and fileUrl is fetched by the MCP server.

Add a tag/label to a Huly issue. Creates the tag if it doesn't exist in the project.

Add a relation between two issues. Relation types: 'blocks' (source blocks target — pushes into target's blockedBy), 'is-blocked-by' (source is blocked by target — pushes into source's blockedBy), 'relates-to' (bidirectional link — updates both sides). targetIssue accepts cross-project identifiers like 'OTHER-42'. No-op if the relation already exists.

Upload a local path, URL, or base64 payload and attach the native file reference to one exact lead.

Add a Markdown comment to one exact lead. Current-workspace Huly links are stored as native references.

Idempotently attach a label relation to one exact lead. Accepts a definition ID or exact title; a missing title creates the Lead label definition.

Subscribe a workspace member to object notifications by adding a core collaborator row. Member can be an account UUID, exact employee/person name, or email. Idempotent when already subscribed.

Idempotently add a contact channel to an organization identified by ID or exact unique name. Provider labels: email, phone, linkedin, twitter, github, facebook, telegram, homepage, whatsapp, skype, profile, viber. Returns added=false and the existing channel when the exact provider+value already exists.

Link a person as a member of an organization. The person appears under the org's Members tab in Huly. Use person ID or email to identify the person. Idempotent: returns added=false if that person is already a member.

Upload and attach a file to one person from exactly one of filePath, fileUrl, or base64 data; person must contain exactly one exact locator: {id}, {email}, or {name}; duplicate email/name matches fail as ambiguous.

Idempotently add a contact channel to a person. Person accepts person ID, exact email address, or exact Huly display name. Provider labels match list_contact_channel_providers. Returns added=false and the existing channel when the exact provider+value already exists.

Add a markdown note/comment to one person; person must contain exactly one exact locator: {id}, {email}, or {name}; duplicate email/name matches fail as ambiguous. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Add an emoji reaction to an activity message.

Attach a file to a Recruiting vacancy, candidate, applicant, or opinion target. Provide filename, contentType, and exactly one source: filePath is resolved on the MCP server host, data is client-local base64 content, and fileUrl is fetched by the MCP server.

Attach a skill to a candidate. candidate accepts person _id, email, or exact name. skill accepts title or tag ID; missing skill titles are created. Optional category/color apply only to newly created skill tags.

Add a Markdown comment directly to a Recruiting vacancy, candidate, applicant, review, or opinion target resolved by the shared target locator. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Idempotently add a Huly Related Issues entry (`Issue.relations`) from a tracker issue to a Recruiting vacancy, candidate, or applicant target.

Idempotently add members to an existing Huly space. Members accept account UUID, exact email, or exact person display name and resolve to Huly account UUIDs before replacing the full members array.

Idempotently add members to one role on a typed Huly space while preserving all other role assignments. Role accepts a raw role _id or exact role name from the space's SpaceType. Members accept account UUID, exact email, or exact person display name.

Add a child (sub-task) template to an issue template. The child defines default values for sub-issues created when using create_issue_from_template. Child description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Returns the child template ID.

Add a test case to a test plan. Resolves test case by ID or name. Optionally assign a person by email or name.

Add a reply to a message thread. Reply body supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Idempotently attach a label to a Planner ToDo resolved by raw ID or human locator. label accepts a definition ID or exact title; a missing title creates the ToDo label definition first, while duplicate exact titles return candidate IDs.

Approve an active approval Request as the current Huly user. The current user's Employee/Person ref must be in the request's requested list. Optionally attach a markdown decision comment before approval. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. If the current user already approved it, returns changed=false.

Archive all notifications. Returns the count of notifications archived.

Archive a Huly board by board _id or exact board name. This hides the board but does not delete cards.

Archive a board card. card accepts _id, CARD-123, bare number, or exact title scoped to the board.

Archive a Huly channel by channel name or ID. This is reversible with unarchive_channel and is idempotent when the channel is already archived.

Archive a funnel without deleting it. Returns lead/comment/attachment impact so the caller can assess the hidden native content. Already archived funnels are an idempotent no-op.

Archive a notification. Archived notifications are hidden from the main inbox view. Idempotent when already archived.

Archive all inbox notifications in a notification context. Idempotent: returns count 0 when no active notifications remain.

Archive a Recruiting vacancy by raw _id, VCN-<number>, bare number, or exact name.

Assign an exact employee ID/email/display name by writing only authoritative Staff.department. Use department=null to clear. Department.members hierarchy propagation is performed asynchronously by Huly's server trigger.

Attach a generic Huly tag to one raw object collection. Prefer module tools for supported issue, document, Planner, board, and recruiting objects; this SDK fallback requires targetClass plus objectId/objectClass/space/collection and is idempotent for the same object, collection, and tag.

Cancel an active approval Request created by the current Huly user. This is the safe removal-from-workflow operation; hard delete is intentionally not exposed.

Idempotently cancel one Huly Process execution by execution ID. Active executions are marked cancelled; already-cancelled executions succeed with cancelled=false; completed executions fail without changing history.

Complete a Planner ToDo by raw todoId or human locator, including a document attachment locator, by setting doneOn. Huly may trim future work slots and run issue automation when the ToDo is attached to an issue.

Idempotently create one Huly association definition between two non-system classes. Use sourceClass/targetClass with sourceRole/targetRole and cardinality; returns an existing identical association by default.

Create a Huly board. Idempotent by exact active board name; pass projectType by _id or exact name only when the default board project type is ambiguous.

Create a board card with safe defaults. Resolves kind/status from the board project type, increments the CARD-number sequence, and stores markdown description as inline Huly Markup. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Create a board label definition for board cards. Idempotent by exact title when one label matches; uses board.category.Other when no default category exists.

Create a new card in a Huly card space. Requires a master tag (card type). Content supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Returns the created card id.

Create a new channel in Huly. Returns the created channel ID and name.

Create a new component in a Huly project. Components help organize issues by area/feature. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Returns the created component ID and label.

Create a top-level or nested HR department. Parent and people use exact paths/IDs/names/emails and reject ambiguity. Names cannot contain '/'. Department.members starts empty and remains server-derived.

Open a one-to-one direct-message conversation with a workspace member. The `person` argument accepts an email or exact display name (e.g. `Smith,Bill`). Idempotent: if a DM with that participant already exists, returns it (`created: false`); otherwise creates a new DM (`created: true`). The returned `id` can be passed as `dm` to send_dm_message, list_dm_messages, etc.

Create a new document in a Huly teamspace. Content is markdown and supports native Mermaid diagrams (```mermaid blocks render interactively in Huly UI). Use markdown links to current-workspace Huly browse URLs for native references; Huly browse links returned in get_document content round-trip as native references. The URL identifies the object; link text is display text; plain issue keys stay text. External URLs stay normal markdown links. Optionally pass parent as a document title or ID to create a nested child document; invalid parents fail instead of silently creating a top-level document.…

Create a drawing under a raw Huly parent object.

Idempotently create a Huly Drive space. If an active Drive with the same exact name already exists, returns it with created=false. Initial members and owners accept account UUIDs, exact emails, or exact person names; omitted lists default to the caller.

Idempotently create a Drive folder path, creating missing parents like mkdir -p. Returns created=false when the full folder path already exists.

Create a new calendar event. Description supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Optional calendarId targets a specific calendar; when omitted, the event uses the authenticated user's primary personal calendar. Optional meetingRoom.room resolves an ID first, then an exact unambiguous name; meetingRoom.floor disambiguates names only. It creates the native Meeting assignment for every eventId sibling without replacing location. Ret…

Create a native Huly funnel after validating its Funnel project type, Lead task types, workflow statuses, membership, and owners. Full description accepts Markdown and preserves current-workspace native references. Creation is idempotent only for one exact existing name; the result explicitly reports whether that existing funnel is archived, and ambiguous names are rejected.

Open a group direct-message conversation with at least two other workspace members. The `people` array accepts exact emails or exact display names; the authenticated account is included automatically. Idempotent by exact sorted member set: returns an existing group DM with `created: false` when one already exists. For one other person, use create_direct_message.

Create an employee-attached HR request using exact employee, department, and request-type resolution. Dates are inclusive calendar dates in YYYY-MM-DD form and descriptions accept Markdown with native Huly references.

Create a custom Huly Attribute/property on a class resolved by exact ID, tail name, or label. Supports string, number, boolean, date, markup, enum, and reference types; enum and reference targets also resolve by name. Existing same-name attributes are idempotent only when their definition matches; otherwise the call returns a conflict. New records are always isCustom=true. This changes workspace model metadata. confirm=true is required so an agent cannot mutate the model accidentally.

Create a Huly model enum with ordered option values. An exact case-insensitive name is idempotent only when its ordered values match; otherwise the call returns a conflict. This changes workspace model metadata. confirm=true is required so an agent cannot mutate the model accidentally.

Create a base Huly Permission with a clear human label and optional class/transaction constraints. Class accepts an exact class ID, tail name, or label. Exact labels are idempotent only when the full definition matches. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Create a zero-valued standard Sequence or prefixed CustomSequence for a class resolved by exact ID, tail name, or label. Retrying returns the matching existing definition and never resets or increments its counter; a different kind or prefix returns a conflict. This changes a workspace sequence definition. confirm=true is required so an agent cannot mutate sequence metadata accidentally.

Create an inventory category. Defaults parentCategory to the Inventory root. Rejects duplicate category names under the same parent.

Create an inventory product in a category resolved by ID or exact name. Rejects duplicate product names in the same category.

Create an inventory variant/SKU under a product resolved by ID or exact name. Rejects duplicate variant names or SKUs in the same product.

Create a new issue in a Huly project. Assignee accepts an email, Person display name, or exact agent UserProfile title and always stores the linked Person. Omit parentIssue for a native top-level issue, or specify parentIssue to create a sub-issue. Optionally set taskType by ID or display name; it is resolved within the target project's project type, and status is validated against that task type's workflow. Use list_task_types or get_project_type to discover valid task types and statuses. Description supports markdown formatting; markdown links to current-workspace Huly browse URLs with _clas…

Create a new issue from a template. Applies template defaults, allowing overrides for specific fields. Description override supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. If the template has children (sub-task templates), sub-issues are created automatically unless includeChildren is set to false. Returns the created issue identifier and count of children created.

Description is built at runtime.

Create a new issue template in a Huly project. Templates define default values for new issues. Template and child descriptions support markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Optionally include children (sub-task templates) that will become sub-issues when creating issues from this template. Returns the created template ID and title.

Create a new label/tag definition in the workspace. Labels are global and can be attached to any issue. Returns existing label if one with the same title already exists (created=false). Use add_issue_label to attach a label to a specific issue.

Create one native Huly lead in an active funnel for an existing person or organization. Resolve the funnel by ID or exact name; identify the customer explicitly as person or organization; optionally choose an employee assignee, a workflow status matched exactly after normalization (trimmed, case-insensitive, and ignoring spaces, hyphens, and underscores), and Markdown description. Automatically applies the Customer mixin when needed, preserves native Huly references, and returns both leadId and LEAD-<number>. This tool never creates a person or organization inline.

Create a new milestone in a Huly project. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Returns the created milestone ID and label.

Create one durable virtual-office Floor with a nonblank name. Returns the generated floorId immediately. Floor rename and deletion are intentionally unavailable.

Create one durable video, audio, reception, or personal office on a Floor resolved from an exact ID or unambiguous exact name. Video/audio/reception require a nonblank name; office uses Huly's native empty name and person=null. Huly class, access, language, 2x1 free floor-plan position, and recording/transcription defaults are derived internally; video inherits workspace OfficeSettings while other kinds default both flags to false. This does not create participants or start recording/transcription.

Create a new organization in Huly. Optionally add members by person ID or email. Fails if any requested member cannot be resolved. Returns the created organization ID.

Create a new person in Huly. Returns the created person ID.

Create a new Huly tracker project. Idempotent: returns existing project if one with the same identifier already exists (created=false). Identifier must be 1-5 uppercase alphanumeric chars starting with a letter.

Create one public holiday for an exact department ID or full path. The date is a timezone-independent Gregorian calendar day stored as Huly TzDate with UTC offset 0; duplicate department/date pairs are rejected.

Create an applicant linking one vacancy and candidate. Rejects duplicate vacancy/candidate pairs, increments APP sequence, resolves status from that vacancy workflow, and recruit-enables the person if needed.

Create a Recruiting opinion on one review. Increments the OPE sequence, attaches to the review opinions collection, and stores markdown description as Huly markup. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Create a Recruiting review/interview like the Huly UI: increments RVE sequence, attaches to the candidate reviews collection, stores markdown description as Huly markup, defaults dueDate to 30 minutes after date, and recruit-enables the person if needed. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Create a Recruiting vacancy like the Huly UI: increments the vacancy sequence, stores fullDescription as markdown-backed collaborative markup, defaults members/owners to the current account, and creates vacancy type-data mixin {}. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Create a new recurring calendar event with RFC5545 RRULE rules. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Optional calendarId targets a specific calendar; when omitted, the event uses the authenticated user's primary personal calendar. Returns the created event ID.

Idempotently create one concrete relation between two resolved documents for a writable association. Endpoint locators support raw, issue, document, card, and exact funnel-scoped lead targets. Enforces association endpoint classes, direction, duplicate handling, automation-only restrictions, and cardinality. Published Relation endpoints have no mutable field; replace a relation with delete_relation then create_relation.

Create a calendar schedule. Owner accepts an employee/person ID, exact name, or email; calendar can be targeted by calendarId or calendarName. Optional meetingRoom.room resolves an ID first, then an exact unambiguous name; meetingRoom.floor disambiguates names only and creates the native MeetingSchedule composition. Meeting-room schedules must be owned by the authenticated caller.

Create a generic Huly typed space by SpaceType _id or exact name. This single call resolves member, owner, and role locators; applies SpaceType default members; and creates role assignments. For safety, only non-system types whose SDK descriptor base class is exactly core:class:TypedSpace are supported. Specialized project, teamspace, drive, funnel, vacancy, and similar types fail with a typed error directing callers to their purpose-built tools. Defaults: private=false, autoJoin=false, restricted=false, owners=[calling account].

Create a Huly role definition using a SpaceType ID or exact name and permission ID or exact label values. The call creates both the attached Role and required typed-space assignment attribute, compensating if the second write fails. Workspace-scoped permissions are restricted to the stable all-spaces SpaceType. Existing exact role names are idempotent only when permission sets match. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Create a generic Huly StatusCategory for an attribute resolved by ID or exact name. defaultStatus is resolved within the same attribute, preserving the category/default relationship. Idempotently returns an existing normalized label with created=false.

Create a generic Huly tag definition for one targetClass. Idempotent by targetClass + title. Prefer module label or skill tools when attaching to a supported object; use this raw fallback for definition administration and unsupported tag-backed domains.

Create a new tag/label category. Idempotent: returns existing category if one with the same label and targetClass already exists (created=false). Defaults targetClass to tracker issues.

Add a Huly issue/task type to a project type idempotently by normalized name. Copies required workflow configuration from an existing template task type unless templateTaskType is supplied. Returns created, IDs, affected task type IDs, and a workspace-level workflow warning.

Create a new Huly document teamspace. Idempotent: returns existing teamspace if one with the same name exists.

Create a test case attached to a suite. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Requires project and suite. Defaults: type=functional, priority=medium, status=draft.

Create a test plan in a project. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Idempotent: returns existing plan if one with the same name exists (created=false).

Create a test result in a run. Resolves test case by ID or name. Status defaults to 'untested'.

Create a test run in a project. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. For bulk creation from a plan, use run_test_plan instead.

Create a test suite in a test project. Idempotent: returns existing suite if one with the same name exists (created=false). Optional parent for nesting.

Create a Planner ToDo. Omit attachedTo for a personal ToDo, pass attachedTo.type=issue with project and identifier for an issue action item, or pass attachedTo.type=document with teamspace and document names or IDs for a document action item. Document ToDos are private by default. Omit owner to use the authenticated user. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Create a generic Huly workflow Status for an attribute resolved by ID or exact name. Optionally resolve a shared category by ID or exact label; pass a category ID when its label is ambiguous. Idempotently returns the existing normalized name in that attribute with created=false. Tracker project-type wiring remains owned by create_issue_status.

Create a new Huly workspace. Returns the workspace UUID and URL. Optionally specify a region.

Preview or execute an employee lifecycle change resolved by exact email or exact display name. action=deactivate only sets Employee.active=false and retains workspace membership; action=kick then removes the linked account from the workspace. If workspace removal fails after deactivation, the typed partial failure lists completed changes and directs a safe preview-and-retry. Preview is the default. Execution requires execute=true plus one exact expected relationship object copied from the preview: unlinked, linked-without-membership, or workspace-member. Any changed Person ID, account UUID, Em…

Delete a generic activity reply.

Idempotently delete one Huly association definition only when no concrete relations reference it. If relations exist, delete_relation must clean them up first; deleting an already-missing association is a successful no-op.

Permanently delete an attachment. This action cannot be undone.

Permanently delete an already archived board card using Huly removeCollection. Active cards are rejected; call archive_board_card first.

Delete one board label definition by TagElement _id or exact title. This removes the label definition, not a board card.

Permanently delete a Huly card. This action cannot be undone.

Permanently delete one comment that belongs to the resolved Huly card. Resolves the card space by exact name or ID and the card by exact title or ID. This action cannot be undone.

Permanently delete a Huly channel. This action cannot be undone. For reversible channel lifecycle changes, use archive_channel and unarchive_channel instead.

Permanently delete a channel message. This action cannot be undone.

Delete one file attached directly to a Huly channel message, direct-message message, or thread reply. The attachmentId must belong to the resolved target.

Permanently delete the direct core ClassCollaborators metadata record for a class resolved by ID, tail name, or label. Inherited metadata is never selected or deleted. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Delete a comment from a Huly issue. This action cannot be undone.

Permanently delete a Huly component. This action cannot be undone.

Preview destructive impact by default. Execution requires execute=true plus exact previewed descendant and assigned-Staff counts; Huly then cascades descendant deletion and clears affected Staff assignments.

Permanently delete a direct-message message. The `dm` argument accepts either the DM `_id` or a participant display name; a name resolves only to a one-to-one DM with the authenticated account. This action cannot be undone.

Permanently delete a Huly document. This action cannot be undone.

Delete a drawing. This action cannot be undone.

Permanently delete an empty Huly Drive space. The Drive must contain no files or folders; non-empty Drives fail with child count and item summaries. This is permanent deletion, not archive or trash.

Permanently delete a comment from a Drive file resolved by filePath or fileId. Provide only one locator. This deletes the comment, not the file.

Permanently delete a Drive item, meaning a file or folder. Files are deleted with their version records. Folders must be empty; non-empty folders fail with child count and child summaries. This is permanent deletion, not archive or trash.

Permanently delete a calendar event. This action cannot be undone.

Permanently delete an exact funnel only after it is archived and empty. First call get_funnel or archive_funnel, then pass the observed impact counts as expectedLeads, expectedComments, and expectedAttachments. Deletion fails if any count changed after that preflight snapshot.

Delete one exact HR request. Its comments and attachments are Huly-owned attached collections and follow the request deletion lifecycle.

Delete one file belonging directly to an exact HR request.

Delete a comment that belongs directly to an exact HR request.

Permanently delete an unused custom Huly Attribute resolved by ID or exact name. Pass class by ID/name to disambiguate. Built-in attributes and attributes present on any owning-class document are protected. This changes workspace model metadata. confirm=true is required so an agent cannot mutate the model accidentally.

Permanently delete a Huly model enum resolved by exact ID or name. Refuses deletion while any attribute references it. This changes workspace model metadata. confirm=true is required so an agent cannot mutate the model accidentally.

Permanently delete a custom Huly Permission resolved by exact ID or exact label. Namespaced built-ins are protected, and referenced permissions are refused loudly. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Permanently delete a never-used Sequence or CustomSequence resolved by exact sequence ID or attached class ID/name. expectedCurrentValue must be 0 and is an atomic compare-and-delete guard, so an active or advanced counter cannot be removed; referenced CustomSequence records are protected. This changes a workspace sequence definition. confirm=true is required so an agent cannot mutate sequence metadata accidentally.

Delete an empty inventory category by ID or exact name. Refuses categories that still contain child categories or products; this action does not cascade.

Delete an inventory product by ID or exact name. Refuses products with variants, photos, attachments, or comments; this action does not cascade.

Permanently delete a file attached directly to an inventory product. The attachmentId must belong to the resolved product.

Permanently delete a comment attached directly to an inventory product. The commentId must belong to the resolved product.

Permanently delete a photo attached directly to an inventory product. The photoId must belong to the resolved product.

Delete one inventory variant/SKU by ID, exact variant name, or exact SKU. This action does not delete its product.

Permanently delete a Huly issue. This action cannot be undone.

Permanently delete a Huly issue template. This action cannot be undone.

Permanently delete a label/tag definition. Accepts label ID or title. This action cannot be undone.

Preview native lead deletion impact by default. The preview reads authoritative comment, attachment, and label relation counts. To permanently delete, pass execute=true together with the exact counts returned by the preview; deletion fails if impact changed.

Delete an attachment only when it belongs to one exact lead. The native blob reference remains governed by Huly storage cleanup.

Delete one comment only when it belongs to the exact lead target.

Permanently delete a Huly milestone. This action cannot be undone.

Permanently delete a notification. This action cannot be undone.

Permanently delete an organization identified by ID or exact name when that name is unique. Use with care - this cannot be undone. Useful for cleaning up duplicate organizations after merging their data elsewhere. If multiple organizations share the same name, use the organization ID.

Permanently delete a person from Huly. This action cannot be undone.

Permanently delete an attachment only when it belongs to one resolved person; person must contain exactly one exact locator: {id}, {email}, or {name}; duplicate email/name matches fail as ambiguous.

Permanently delete a note/comment only when it belongs to one resolved person; person must contain exactly one exact locator: {id}, {email}, or {name}; duplicate email/name matches fail as ambiguous.

Permanently delete a Huly project. All issues, milestones, and components in this project will be orphaned. This action cannot be undone.

Permanently delete one public-holiday document by exact raw ID.

Delete an applicant with Huly removeCollection. applicant accepts raw _id, APP-<number>, or number; vacancy/candidate can disambiguate APP numbers.

Delete one comment attached directly to a Recruiting vacancy, candidate, applicant, review, or opinion. The commentId must belong to the resolved target.

Delete a Recruiting opinion with Huly removeCollection. opinion accepts raw _id, OPE-<number>, or number; review can disambiguate.

Delete a Recruiting review with Huly removeCollection. review accepts raw _id, RVE-<number>, number, or exact title; candidate/application can disambiguate.

Delete the spaceRule that chooses the default destination project for related issues from one space. This only deletes spaceRule targets; classRule deletion is intentionally unsupported because class rules may be model-provided.

Idempotently delete one concrete relation by relation ID or by exact association/source/target triple. Triple endpoint locators support raw, issue, document, card, and exact funnel-scoped lead targets. Triple deletes use the same direction semantics as create_relation and fail if the selector is ambiguous.

Delete a calendar schedule by scheduleId.

Permanently delete an unreferenced generic StatusCategory by ID or exact label. Refuses deletion while any Status references the category, preventing dangling relationships.

Delete a generic Huly tag definition by ID or exact title, resolved within targetClass. This deletes the tag definition, not only one object's tag reference.

Permanently delete a tag/label category. Accepts category ID or label name. Labels in this category will be orphaned (not deleted). This action cannot be undone.

Permanently delete a Huly document teamspace. This action cannot be undone.

Permanently delete a test case. Accepts test case ID or name. This action cannot be undone.

Permanently delete a test plan. This does not delete associated test runs. Cannot be undone.

Permanently delete a test run. This does not delete associated test results. Cannot be undone.

Permanently delete a test suite. Accepts suite ID or name. This action cannot be undone.

Permanently delete a thread reply. This action cannot be undone.

Delete a Planner ToDo by raw todoId or human locator, including a document attachment locator. This is destructive; deleting the last open issue ToDo can cause Huly classic issue status automation, while document ToDos do not change issue counters.

Permanently delete an unreferenced generic workflow Status by ID or exact name. Refuses deletion while any StatusCategory default, ProjectType, TaskType, or task record references it. This tool never rewrites tracker workflow arrays; use tracker-specific workflow tools to remove those references first.

Permanently delete the current workspace. This action cannot be undone. Use with extreme caution.

Describe one Huly SpaceType by id or exact name in a single read-only call. Returns descriptor metadata, base/target classes, roles, role permissions, default members, autoJoin, and the stored role-assignment shape.

Detach a generic Huly tag from one raw object collection. Prefer module tools for supported issue, document, Planner, board, and recruiting objects; this SDK fallback requires targetClass and objectId/objectClass/space/collection.

Get download URL for an attachment along with file metadata (name, type, size).

Edit an existing Huly document. You may rename with title and/or edit the body. Body editing has two mutually exclusive modes: (1) content replaces the entire markdown body, (2) old_text + new_text performs exact targeted search-and-replace. Use markdown links to current-workspace Huly browse URLs for native references; Huly browse links returned in get_document content round-trip as native references. The URL identifies the object; link text is display text; plain issue keys stay text. External URLs stay normal markdown links. For targeted replace, multiple matches error unless replace_all is…

Use this to view issue content, comments, classification, or full metadata. identifier accepts a project-local ident…

Read the Huly-persisted external publication state for an issue identified by project and human issue identifier. Returns not_requested, pending, published, or failed; pending includes the ISO state-change timestamp and elapsed time, while published includes an external URL and positive issue number. A timeout is projected as failed only after the bounded wait, and later persisted publication takes precedence. This reads Huly state and never calls the external provider directly.

Retrieve full details for a Huly issue template including children (sub-task templates). Use this to view template content, default values, and child template IDs.

Retrieve one exact funnel-scoped Huly lead with Markdown descriptions, customer identity/type, workflow task type and status, rank/completion, native collection counts, actor timestamps, funnel identity, and explicit classifications for fields without stable published semantics.

Read all applicable custom field values for an existing Recruiting Candidate, including definitions that are currently unset. candidate accepts a person _id, exact email, or exact display name. Candidate and Person-owned fields are projected with their Huly type metadata; this read never enables Recruiting. For a new person, call create_person first, then set_recruiting_candidate_profile.

Get one Recruiting opinion by raw _id, OPE-<number>, or bare number. Pass review to disambiguate. Returns value, markdown description, comments/attachments counts, parent review ref, and timestamps.

Discover Huly support-widget model/setup and the authenticated account's private stored status rows in one read-only call. Returns supported=false when either required workspace classifier is unavailable; otherwise setup is missing when no SupportSystem exists, configured for exactly one, or ambiguous with every candidate instead of choosing nondeterministically. providerConversationId is opaque and storedHasUnreadMessages is only a persisted fallback with no provider-freshness guarantee. Malformed private rows are skipped with an agent warning that never includes provider IDs. Huly exposes no…

Create or promote and invite an employee, or resend an inactive employee invitation. mode=create-or-promote requires the exact Huly display name and email; one checked atomic transaction creates or updates the Person, email SocialIdentity, and active Employee before sending. A changed authoritative precondition sends no invite and directs the caller to retry in a fresh session. mode=invite-existing requires an exact email/name locator and rejects active or non-Employee targets. Omitted role preserves the Employee role; an explicit different role is persisted atomically before resend. Returns n…

Join a non-archived Huly channel as the authenticated account. Idempotent when the account is already a member.

Leave a non-archived Huly channel as the authenticated account. Idempotent when already absent. Refuses to leave if that would leave the channel empty or without any remaining owner.

For provider=telegram, resolve channel by exact stored value or stable contact-channel ID and return newest contentMarkdown, direction, stored Huly sendOn timestamp, and attachment count; returns supported=false when the workspace model or channel is unavailable. Inbound attachment creation is asynchronous, so attachmentCount can temporarily lag the message; attachment bytes are not returned. This proves only Huly-stored records, not provider freshness, an active Telegram connection, or p…

List applicant workflow statuses for one vacancy. vacancy accepts raw _id, VCN-<number>, bare number, or exact name. Statuses are read from the vacancy's ProjectType; they are workspace data, not hardcoded names.

List Huly Recruiting vacancy workflow types. Use the returned type ID or exact type name in create_recruiting_vacancy. Defaults vacancy creation to Huly's Default vacancy type when omitted.

List recurring event definitions. Returns recurring events sorted by modification date (newest first).

List rules that choose the default destination project for related issues. A spaceRule says related issues from one space default to targetProject. A classRule says related issues for one object class default to targetProject. targetProject is a project identifier, or null for no default destination project.

List concrete Huly relation instances under an association, optionally filtered by source and target documents. Endpoint locators support raw, issue, document, card, and exact funnel-scoped lead targets. Requires at least one filter to avoid broad workspace scans.

List saved/bookmarked attachments for the current user.

List saved/bookmarked activity messages.

List calendar scheduling links/availability schedules. Optional owner accepts an employee/person ID, exact name, or email.

List SocialIdentity providers installed in this Huly workspace, returning native provider IDs and types.

List core Huly Permission records for space/workspace access control discovery. Filter by scope, objectClass, or search text. This is read-only and does not assign permissions.

List low-level Huly SpacePreference records. These generic preference rows are attached to spaces and the published SDK exposes only the attached space link, so this tool is read-only discovery. Omit space to list recent rows across spaces, or pass a space _id/exact name with optional class/type narrowing to inspect one space.

List configured Huly SpaceType records. Returns descriptor id, base class, target class, default members, autoJoin, and role count for discovering typed-space configuration.

Description is built at runtime.

List HR Staff and authoritative department assignments. Optionally scope by exact department path/ID, include descendants, and filter Employee active state.

List all issue statuses for a Huly project with workflow category and default info. Returns status name, category, and isDefault. Use this to discover valid statuses before creating or updating issues.

List tag/label categories in the workspace. Categories group labels (e.g., 'Priority Labels', 'Type Labels'). Omit targetClass to include all classes.

List generic Huly tag definitions for one SDK target class. Prefer module tools for issue labels, document labels, Planner ToDo labels, board labels, and recruiting skills; use this as the raw SDK fallback for other tag-backed domains or category administration.

List Huly issue/task types. Optionally filter by projectType ID or display name. Returns task type identity, parent project type, kind, issue class, and available status count.

List all Huly document teamspaces. Returns teamspaces sorted by name. Supports filtering by archived status.

List labels attached to one Planner ToDo. Resolves the ToDo by raw ID or the same human-oriented issue, title, owner, and completion locators used by get_todo.

Description is built at runtime.

List Huly user presence records. Returns account UUIDs, online status, and last modified timestamp. Use this to check who is currently connected; presence is maintained by Huly server sessions. Filter by online or account UUID.

List viewlets from @hcengineering/view model metadata. Use attachTo with a Huly class id such as board:class:Card to scope by rendered document class; use list_huly_classes when you need class ids. The optional viewlet locator accepts a Viewlet _id, exact title, exact variant, or descriptor _id; descriptor ids may return multiple viewlets. Includes descriptor metadata and matching ViewletPreference configs.

List scheduled work slots created by schedule_todo, Huly UI, or other clients. Shows planned time blocks attached to ToDos. Supports filtering by employee and date range.

List read-only Huly Workbench application model declarations by exact URL alias or case-insensitive alias substring. Returns untranslated labelId values, static model flags, the authenticated account's caller-scoped hiddenByPreference state, and summarized declarative space/special/group navigation without executing components, resource callbacks, or query builders. Legacy space-navigation entries without a stable id are omitted with an agent-visible warning. Application presence is not proof that a plugin, integration provider, worker, API, role, permission, or effective browser visibility is…

List generic Huly workflow Status records across the workspace model. Filter by status attribute ID/exact name and category ID/exact label. Returns resolved attribute and category relationships. For one tracker project's issue statuses, use list_statuses instead.

List members in the current Huly workspace with their roles. Returns members with account IDs and roles.

List all workspaces accessible to the current user. Returns workspace summaries sorted by last visit.

Description is built at runtime.

Apply the Customer mixin to an organization so it appears in the Huly Leads > Customers view. Idempotent - safe to call on organizations that are already customers. Takes the organization ID or exact name when that name is unique.

Apply the native Customer mixin to one existing person so it appears in Huly Leads > Customers. Resolve by person ID, exact email address, or exact display name; ambiguous identifiers fail, no person is created, and repeated calls are idempotent.

Mark all unread notifications as read. Returns the count of notifications marked.

Mark a notification as read. Idempotent: returns success when the notification is already read.

Mark a notification as unread. Idempotent: returns success when the notification is already unread.

Preview or execute a native-reference-preserving person merge with an explicitly selected source and survivor; source and survivor must each contain exactly one exact locator: {id}, {email}, or {name}; duplicate email/name matches fail as ambiguous. Preview is the default and reports identities, channels, memberships, comments, attachments, every other model-declared Person/Contact/Employee reference, account eligibility, retained scalar fields, and an exact preflight token bound to canonical affected document IDs, write-routing fields, and scalar/array values. Execution requires execute=true …

Move a Drive item, meaning a file or folder, to another existing folder path in the same Drive without renaming it. Idempotent when the item is already in that folder. Rejects sibling title collisions and rejects moving a folder into itself or a descendant.

Move an issue tree within its project, preserving IDs, identifiers and attributes. issue/parent accept full identifiers or stable IDs; project accepts identifier or stable ID. destination forms: {project: 'HULY'} for project top level, {parent: 'HULY-42'} to infer the parent project, {project: 'HULY', parent: 'HULY-42'} requiring agreement, or {parent: null} for current project top level. Cross-project movement supports complete compatible trees with equal project types and actual supported kind/status, component/milestone references preserved when valid or matched by literal unique name; othe…

Move a native Huly lead to another active funnel after validating both native Funnel project types and Lead workflows. Pass a destination status matched exactly after normalization (trimmed, case-insensitive, and ignoring spaces, hyphens, and underscores), or omit status to map the current status name; incompatible or ambiguous mappings fail without writing.

Pin or unpin an activity message. Idempotent when the pin state already matches.

Pin or unpin an attachment.

Pin or unpin a notification context. Pinned contexts are highlighted in the inbox. Idempotent when the pin state already matches.

Preview the impact of deleting a Huly entity before actually deleting it. Shows affected sub-entities, relations, and warnings. Supports issues, projects, components, and milestones. Use this to understand cascade effects before calling a delete operation.

Request publication of an existing Huly issue as a new issue in Huly's configured external tracker. Identify the issue with project and its human identifier (for example, HULY-123); provider currently accepts only 'github'. Select target by stable Huly target ID or exact name, or omit target only when exactly one enabled target is mapped to the project. Publication is asynchronous: pending means Huly accepted the request, not that an external issue exists. Repeating the same target is safe while pending or published; a failed same-target request retries, while a different target is rejected. U…

Description is built at runtime.

Reject an active approval Request as the current Huly user and attach the required markdown rejection decision comment. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Huly applies rejectedTx when present.

Detach a board label from one board card. Returns detached=false when the label exists but is not attached to that card.

Idempotently remove members from a non-archived Huly channel. Members accept account UUID, exact email, or exact person display name. Refuses removals that would leave the channel with zero members or, when owners exist, no owner among remaining members.

Detach a label from one ordinary Huly document without deleting the reusable label definition. Returns detached=false when the label exists but is not attached; duplicate exact titles return candidate IDs.

Idempotently remove members from an existing Drive. Members accept account UUIDs, exact emails, or exact person names and resolve to Huly account UUIDs before replacing the Drive member list.

Remove a tag/label from a Huly issue. Detaches the label reference; does not delete the label definition.

Remove a relation between two issues. Mirrors add_issue_relation: 'blocks' pulls from target's blockedBy, 'is-blocked-by' pulls from source's blockedBy, 'relates-to' pulls from both sides. No-op if the relation doesn't exist.

Idempotently remove all matching TagReference relations from one exact lead without deleting the reusable label definition.

Unsubscribe a workspace member from object notifications by removing its collaborator row. Member can be an account UUID, exact employee/person name, or email. Idempotent when already absent.

Remove one contact channel from an organization identified by ID or exact unique name. Identify the channel with exactly one locator: channelId, or provider plus value. Returns removed=false when the locator is absent for that organization.

Unlink a person from an organization's members. Reverses add_organization_member. Returns removed: false if the person was not a member. When using an organization name instead of an ID, that name must identify exactly one organization.

Remove one contact channel from a person. Person accepts person ID, exact email, or exact display name. Identify the channel with exactly one locator: channelId, or provider plus value. Returns removed=false when the locator is absent for that person.

Remove an emoji reaction from an activity message.

Detach a Recruiting skill from a candidate by skill title or tag ID. Idempotent when the skill is absent.

Idempotently remove a Huly Related Issues entry (`Issue.relations`) from a tracker issue to a Recruiting vacancy, candidate, or applicant target.

Remove a test case from a test plan by item ID. Get item IDs from get_test_plan.

Detach a label from one Planner ToDo without deleting the reusable label definition. Returns detached=false when the label exists but is not attached; duplicate exact titles return candidate IDs.

Rename a Drive item, meaning a file or folder, in its current folder. Idempotent when the title is unchanged. Rejects sibling title collisions; use move_drive_item to change folders.

Render one global Huly message template by template ID or exact title. Substitutes only caller-provided values for matching dollar-brace placeholder field IDs from placeholderFieldIds; does not execute Huly TemplateField provider resources. Unresolved placeholders remain in renderedMessage and are reported in unresolvedFieldIds.

Reopen a completed Planner ToDo by raw todoId or human locator, including a document attachment locator, by clearing doneOn. Human locators search completed ToDos by default; raw todoId locators target that exact ToDo.

Apply only Huly's native safe, idempotent SocialIdentity repairs from the authenticated person's authoritative account record: recreate missing active projections, promote verification, reassign an unverified identity after an account merge, and propagate authoritative deletion; person must contain exactly one exact locator: {id}, {email}, or {name}; duplicate email/name matches fail as ambiguous. Another account-linked person, verified cross-person reassignment, arbitrary active type/value/key changes, removal of workspace-only identities, and key collisions return a Huly-specific unsupported…

Attempt the Huly private-channel request-access workflow by channel name or ID. The current Chunter SDK/model has no stable request-access record or server action, so this build returns supported=false with a stable reasonCode and performs no mutation.

Restore an existing Drive file version by version id or numeric version. Idempotent when the requested version is already current and does not increment the file version counter.

Execute a test plan: creates a test run and one test result per plan item. Returns the run ID and count of results created. Optionally name the run and set a due date.

Save/bookmark an attachment for later reference. Idempotent when already saved.

Save/bookmark an activity message for later reference.

Schedule a Planner ToDo by raw todoId or human locator, including a document attachment locator. Creates a Planner-visible blocking work slot on the authenticated user's personal calendar, owned by their primary social identity and including them as a participant. Fails actionably when the identity, employee, or writable calendar prerequisite is unavailable.

Send a message to a Huly channel. Message body supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Send a message to a direct-message conversation. The `dm` argument accepts either the DM `_id` or a participant display name; a name resolves only to a one-to-one DM with the authenticated account. Message body supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Idempotently pin or unpin a top-level message or thread reply located inside exactly one Huly channel or direct-message conversation. Provide `channel` or `dm`, plus the messageId; the message must belong to the resolved conversation.

Create or replace direct core ClassCollaborators metadata for a class resolved by class ID, tail name, or label. fieldSelection supports all person-like fields, no fields, or exact property names validated against the class and its ancestors. Security propagation flags are normalized explicitly. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Set the authenticated user's closed/visible state for exactly one conversation. Provide either `channel` or `dm`, plus `closed`. Closing only hides the current user's notification context; it does not leave channels or remove members.

Set the authenticated user's starred state for exactly one conversation. Provide either `channel` (channel name or ID) or `dm` (DM ID, or one-to-one participant display name), plus `starred`. Creates the missing notification context when needed.

Set a custom field value on a document. Requires the document ID, class, field ID (from list_custom_fields), and value. Values are parsed before Huly writes: numbers from numeric strings, booleans from 'true'/'false', and strings as-is. Date fields accept only a real YYYY-MM-DD calendar date (UTC midnight) or a canonical non-negative epoch-millisecond string from 0 through 8640000000000000. If a date is rejected, remove any time, time-zone suffix, sign, whitespace, decimal, or exponent and retry with one of those exact forms.

Replace owners on an existing Drive. Owners accept account UUIDs, exact emails, or exact person names. By default, each owner is also ensured as a Drive member. Pass owners=[] to clear owners.

Idempotently set an employee's official position on contact.mixin.Employee. employee must be an object with exactly one locator field: {id}, {email}, or {name}; combined locator modalities are rejected. The selected ID, email, or display name is exact, and duplicate email/name matches are rejected. The position field is required: pass a string to set it, or null/an empty string to clear it. Omitting position fails schema parsing and performs no mutation. This updates the Contact Employee mixin, not an HR Staff record.

Replace the workspace-wide Huly space-admin list. Admins accept account UUIDs, exact emails, or exact person display names; pass admins=[] to clear the role. The tool resolves the stable core all-spaces space and Admin role internally.

Set or clear the component on a Huly issue. Pass null for component to clear it.

Set or clear the milestone on a Huly issue. Pass null for milestone to clear it.

Set the authenticated caller's primary personal calendar by calendarId or an unambiguous exact calendarName. The target must be caller-owned, visible, and Writer or Owner. Creates or updates the single PrimaryCalendar preference and never changes provider defaults.

Description is built at runtime.

Create or update the Recruiting Candidate profile mixin on an existing person. For a new candidate, call create_person first, then call this tool with the returned Person ID (or exact email/name). candidate accepts person _id, email, or exact display name. Provide at least one of title, source, onsite, remote.

Set the default destination project for related issues from a space or object class. For space, creates or updates a spaceRule. For objectClass, only updates an existing classRule; this tool never creates classRule targets. Pass targetProject as a project identifier, or null to clear the default destination project.

Replace owners on an existing Huly space. Owners accept account UUID, exact email, or exact person display name. By default, owners are also ensured in members.

Replace members assigned to one role on a typed Huly space while preserving all other role assignments. Role accepts a raw role _id or exact role name from the space's SpaceType. Members accept account UUID, exact email, or exact person display name; pass members=[] to clear this role.

Replace one existing role definition's permission set. SpaceType accepts an ID or exact name, role accepts an ID or exact name scoped to that SpaceType, and each permission accepts an ID or exact label. Pass permissions=[] to clear the role. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Start a new active Huly Process workflow execution on a card/document. Accepts process ID or exact process name, and card/document ID or exact title; ambiguous names or titles fail with candidate IDs. This is not idempotent: each successful call creates a new execution unless the process forbids parallel active executions for the same card, in which case the existing active execution ID is returned in a typed error.

Start a client-side timer on a Huly issue. Validates the issue exists and returns a start timestamp. Use log_time to record the elapsed time when done.

Stop a client-side timer on a Huly issue. Returns the stop timestamp. Calculate elapsed time from start/stop timestamps and use log_time to record it.

Subscribe the authenticated account to notifications for a raw Huly object by adding a core collaborator row. Idempotent when already subscribed.

Attempt to translate a located Huly channel/DM message to targetLanguage. Current Huly translation is browser-only, uses an optional AI endpoint, and stores results only in UI state; this build returns supported=false with a stable reasonCode and does not fabricate translated text.

Unarchive a Huly board by board _id or exact board name.

Unarchive a board card. card accepts _id, CARD-123, bare number, or exact title scoped to the board.

Unarchive a Huly channel by channel name or ID. Idempotent when the channel is already active.

Unarchive a notification so it can appear in active notification lists again. Idempotent when already active.

Unarchive all archived inbox notifications in a notification context. Idempotent: returns count 0 when no archived notifications remain.

Unarchive a Recruiting vacancy by raw _id, VCN-<number>, bare number, or exact name.

Remove a document link from an issue. Idempotent: no-op if the document is not linked.

Remove an attachment from saved/bookmarks.

Remove an activity message from saved/bookmarks.

Remove ToDo work slots. Pass either workSlotId to remove one slot, or a raw ToDo ID/human locator (including a document attachment locator) with scope=all or scope=future and optional from.

Unsubscribe the authenticated account from notifications for a raw Huly object by removing its collaborator row. Idempotent when already absent.

Update a generic activity reply body. Body supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update attachment metadata (description, pinned status).

Update a Huly board's name, description, or privacy. board accepts board _id or exact board name.

Update board card fields: title, markdown description, status, assignee, members, location, cover, startDate, and dueDate. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. Use null to clear clearable fields.

Update a board label definition by TagElement _id or exact title. At least one of title, color, description, or category is required.

Update local visibility and/or hidden settings on one authenticated caller-owned calendar. Visibility accepts public, freeBusy, or private. Hidden changes are allowed only for ExternalCalendar rows and require Writer or Owner access; internal-calendar hiding and provider-owned fields are rejected.

Update fields on an existing Huly card. Only provided fields are modified. Content updates support markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update one comment that belongs to the resolved Huly card. Resolves the card space by exact name or ID and the card by exact title or ID. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update fields on an existing Huly channel. Only provided fields are modified.

Update a channel message. Only the body can be modified; body supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update description and/or pinned state for a file attached directly to a Huly channel message, direct-message message, or thread reply. The attachmentId must belong to the resolved target.

Update an existing comment on a Huly issue. Comment body supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update fields on an existing Huly component. Only provided fields are modified. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Rename, move, or replace department metadata and people. Rejects duplicate sibling names, parent cycles, and moves of subtrees with server-derived members; clear Staff.department assignments before moving a populated subtree. newParent=null moves top-level; teamLead=null clears. Never writes Department.members.

Update a direct-message message. The `dm` argument accepts either the DM `_id` or a participant display name; a name resolves only to a one-to-one DM with the authenticated account. Only the body can be modified; body supports markdown formatting. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update drawing content. Pass null content to clear it.

Update safe metadata on an existing Drive: name, description, private, archived, or autoJoin. Provide at least one update field. This changes the Drive space, not files or folders inside it.

Update a comment on a Drive file resolved by filePath or fileId. Provide only one locator. Idempotent when the comment body is unchanged. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update fields on an existing calendar event. Only provided fields are modified. Description updates support markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links. meetingRoom changes an existing native Meeting only (ordinary Events are rejected), resolves room ID first then exact name with optional floor disambiguation, and updates every eventId sibling without replacing location. Room removal is not supported.

Update a funnel resolved by stable _id or exact unambiguous name. Validates the existing Funnel project type/workflow and membership before mutation. Null clears description or fullDescription; Markdown native references are preserved.

Update selected HR request fields by exact request ID. Department and type locators resolve exactly; omitted fields are preserved. Dates remain inclusive YYYY-MM-DD calendar dates.

Update description and/or pinned state for a file belonging directly to an exact HR request.

Update a comment that belongs directly to an exact HR request.

Update label, index, automation-only, or hidden state for a Huly Attribute resolved by ID or exact name. Pass class by ID/name to disambiguate. Built-in attributes permit hidden-only updates; all other built-in mutations are protected, and property keys/types cannot be changed here. Hide/unhide uses the SDK behavior exercised by Huly settings. This changes workspace model metadata. confirm=true is required so an agent cannot mutate the model accidentally.

Set only the prefix of a CustomSequence resolved by exact sequence ID or attached class ID/name. The compare-and-set guard does not change the counter and refuses a concurrent change; standard Sequence records are protected. This changes a workspace sequence definition. confirm=true is required so an agent cannot mutate sequence metadata accidentally.

Update a Huly model enum resolved by exact ID or name. Renaming and adding options are safe; removing an option is refused while any attribute references the enum. This changes workspace model metadata. confirm=true is required so an agent cannot mutate the model accidentally.

Update a custom Huly Permission resolved by exact ID or exact label. Namespaced built-in permissions are protected. Label/description changes are allowed on unreferenced custom permissions; semantic changes are refused while referenced by a role or SpaceType descriptor. Null clears optional constraints. This changes workspace access-control metadata. confirm=true is required so an agent cannot mutate security configuration accidentally.

Rename and/or move an inventory category. category accepts ID or exact name; pass parentCategory when a name may be duplicated. Rejects duplicate names in the destination parent and self/descendant moves.

Rename and/or move an inventory product. product accepts ID or exact name; pass category when a name may be duplicated. Rejects duplicate names in the destination category.

Update description and/or pinned state for a file attached directly to an inventory product. The attachmentId must belong to the resolved product.

Update a comment attached directly to an inventory product. The commentId must belong to the resolved product. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Rename and/or change the SKU of an inventory variant. variant accepts ID, exact name, or exact SKU; pass product when needed. Rejects duplicate names or SKUs in the same product.

Update fields on an existing Huly issue. Assignee accepts an email, Person display name, or exact agent UserProfile title and always stores the linked Person; use null to unassign. Optionally set taskType by ID or display name; it is resolved within the target project's project type, and the status is preserved only when valid for the new task type. Use list_task_types or get_project_type to discover valid task types and statuses. Only provided fields are modified. Description updates support markdown; markdown links to current-workspace Huly browse URLs with _class, _id, and label become nati…

Update fields on an existing Huly issue template. Only provided fields are modified. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Update fields on an existing Huly milestone. Only provided fields are modified. Description supports markdown. Markdown links to current-workspace Huly browse URLs with _class, _id, and label become native Huly references; external URLs and other-workspace browse URLs stay normal links.

Enable or disable a notification provider setting. Validates providerId against authoritative model definitions when available; compatible REST fallback is preserved and explicitly warned.

Enable or disable one notification type for one provider. Validates both IDs against authoritative model definitions when available, and creates a type setting only when the provider is configurable. Compatible REST fallback is preserved and explicitly warned.

Update one durable Room or Office by roomId. Accepts only name, Markdown description, access, startWithTranscription, and startWithRecording. Personal offices reject open access; Huly's protected Reception cannot be renamed. Floor, geometry, person assignment, language, ACLs, occupancy, and active provider state are preserved. Default flags affect future sessions and do not start or stop recording/transcription.

Update fields on an existing organization identified by ID or exact name when that name is unique. Only provided fields are modified.
