Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• add_comment

  Post a comment on a diagram. Pass nodeId to pin it to a specific node, or parentId to reply to an existing top-level comment (threads are one level deep). The author is the API token's owner. Use this to leave structured review findings a human will see on the diagram.

• analyze_diagram

  Analyze a stored flowchart diagram's structure (nodes, edges, subgraphs) and return actionable findings — orphan nodes, over-connected hubs, cycles, disconnected clusters, and grouping suggestions. Flowchart diagrams only. Set postAsComments: true to also persist each finding as a comment on the diagram (node-pinned where the finding names a single node) so a human reviewer sees them on the diagram surface.

• create_deck

  Create a presentation deck from existing diagrams. Pass `slides` as the complete ordered list of diagram ids — the deck plays them as a slideshow in that order. Typical flow: create_diagram for each slide, collect the returned ids, then create_deck with those ids in presentation order. Returns the deck id and the present URL, which only members of this Space can open — it is NOT a shareable link. To share the deck outside the Space, someone in the Space opens it in DiagramZu and uses its Share button, which mints a public read-only presentation link. Diagram ids must already exist in this Spac…

• create_diagram

  Create a new diagram in the Space. Returns its id and its URL in the app, which only members of this Space can open — it is NOT a shareable link. To show the diagram to anyone outside the Space, someone in the Space opens it in DiagramZu and uses its Share button, which mints a public read-only link. See this server's instructions for diagram-type selection and `class` role names (`edge`/`core`/`data`/`accent`/`muted`) for color-grouping.

• create_page

  Create a Markdown page in the workspace — a design write-up, a decision record, a runbook, the prose a diagram cannot carry. The title comes from the body (front-matter `title`, else the first top-level `#` heading), so begin the body with a heading rather than passing `title`. Embed a stored diagram by putting its id inside a fenced `diagramzu` block; an inline `mermaid` block is for a throwaway sketch nobody will revisit. Returns the page's id, its revision and its URL in the app, which only members of this workspace can open. To let somebody outside the workspace read it, a person in the wo…

• get_deck

  Fetch one deck by id. Returns its title, description, and the ordered list of slides (each slide is a diagram id + title in presentation order).

• get_diagram

  Fetch one diagram by id. Returns its title, description (the agent's brief), mermaid source code, and its URL in the app — which only members of this Space can open. If the diagram already has a public link, that link is reported separately on a `Share (public, read-only):` line; a public link is minted by a person, from the diagram's Share button. Read the description before editing — it tells you what the diagram is for and when to update it.

• get_page

  Fetch one Markdown page by id. Returns its body, its `revision` — pass that as `baseRevision` when replacing the whole body — its language, who edited it last, and its URL in the app, which only members of this workspace can open. To let somebody outside the workspace read it, a person in the workspace opens the page in DiagramZu and uses its Share button, which mints a public read-only link. For a long document prefer `outline: true` (the heading tree, with an anchor per heading) and then `section: '<heading text or anchor>'` for just the part you need.

• get_version

  Fetch one snapshot by id. Returns its title, mermaid source code, and metadata. Read-only — restore is human-only in the UI.

• list_comments

  List comments on a diagram, oldest first. Returns id, parentId (null for a top-level comment), nodeId (the pinned node, if any), author, resolved state, and a body snippet. Use nodeId to fetch only the thread pinned to one node.

• list_decks

  List presentation decks in the configured Space, newest-edited first. A deck is an ordered set of existing diagrams shown as a slideshow. Returns each deck's id, title, and slide count.

• list_diagrams

  List diagrams in the configured Space (every folder, newest first by default). Use this BEFORE create_diagram to check whether a diagram with the target purpose already exists — if it does, prefer update_diagram over creating a duplicate. Filter with `q` (case-insensitive substring on title, description, or code) when looking for a named diagram (e.g. q: 'schema' or q: 'infra'). Sort with `sort: 'updated'` to find the most recently changed diagrams, or `sort: 'relevance'` when `q` is set so a title hit ranks above a description or code hit.

• list_folders

  List every folder in the configured Space, ordered by name. Returns id and full path (e.g. 'Infra/AWS' for a nested folder). Use this BEFORE create_diagram or update_diagram when you want to place a diagram in a meaningful folder — agents should match by name (e.g. find a folder named 'Schemas' and pass its id as folderId). Folders are at most two levels deep. Creating folders is currently human-only.

• list_pages

  List the workspace's Markdown pages, most recently edited first. Returns each page's id, title, revision, last-edit time, who edited it, and a short snippet — never the full body; call get_page for that. Filter with `q`, a case-insensitive substring over title and body that works in Chinese and Japanese too, and pass `sort: 'relevance'` with it so a title hit ranks first. Call this BEFORE create_page to see whether a page on the topic already exists — prefer update_page over writing a second one.

• list_spaces

  List every workspace this connection can act in. Returns each workspace's id, slug, name, your role, and which one is the default (the workspace used when a tool is called without `space`). Call this FIRST when the user mentions a workspace by name, or when you are not sure which workspace the work belongs in — then pass the id as `space` on the tool you actually want. A connection scoped to a single workspace returns just that one.
