As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].
add_knowledge_fileAdd a local file's content to a knowledge base (txt/md/html/pdf/docx). **This MCP runs on the platform server and cannot read paths on YOUR machine.** For text files, read the content yourself and call `add_knowledge_text`; for binaries (pdf/docx), upload via the console, or curl `/knowledge-bases/{name}/documents/upload`. **To ingest a whole folder, zip it and send that one endpoint** — subdirectories are walked, md/txt/pdf/html/docx are ingested one by one, and document names use the in-archive relative path (`2025/rates.pdf` vs `2026/rates.pdf` therefore never coll…
add_knowledge_textAdd a **text** document to a knowledge base (chunking + embedding happen synchronously; returns the real chunk count). For **local files** (pdf/docx…) see `add_knowledge_file`.
build_knowledge_indexBuild (or rebuild) the structured index for a knowledge base — the second leg beside vector search. Vector search answers "what does this passage say". It **cannot count, filter numerically or aggregate**, so "how many documents", "which ones are between 1000 and 2000 words", "how many per category" are not answered badly — they are structurally unanswerable. This builds a small per-KB table from whatever structured header the documents share, which the agent can then query with SQL via `query_knowledge_table`. Only worth it when the documents share a machine-readable…
clone_storylineClone a storyline into a new draft (new key, unpublished, doesn't claim default, no chain pointer) for tweaking.
configure_shareConfigure this share — its name and its **appearance** — fields you don't pass stay as they are (server-side partial merge). - `label`: the name at the top of the chat page, and the browser tab's title. **Renaming a share is this call**; you never need to create a replacement and delete the old one. That would mint a new token, so the link already embedded in the client's site would stop working — the visible name and the address are not the same thing. - `theme_color`: the brand colour, `#RGB` or `#RRGGBB`. **This one colour is all you give** — its foregro…
create_agentCreate an agent. `name` is lower-cased on save — it is a key, not a display name. soul = persona/identity; task = duties and boundaries; tools = tool-name whitelist (check list_tools first; the system tools time/geo/weather **and `compute_chart`** are **auto-enabled by default**, no need to list them — but note that passing `tools` at all replaces that default list, so include them yourself if you pass any); knowledge_bases = attached knowledge base names (once attached, retrieval is injected automatically every turn). `ask_forms` (**on by default**) lets the…
create_knowledge_baseCreate a knowledge base. **Write `description` — it is what routes questions to this base.** Before each answer the platform reads every attached base's `description` and decides which ones this question needs; a base whose description is vague or blank gets searched when it should not, or missed when it should. One line, in the words a visitor would use, naming the subject **and the boundary**: "Country-by-country medical device registration requirements — not company or pricing information." It is also the line shown in the console list, but that is the lesser job. …
create_shareCreate a **share / integration entry point** for an agent — this is how end users actually reach it. **`published=True` only means "visible", not "reachable"**: for end users to talk to the agent you must create a share. The response carries a directly openable chat link (`{public_base}/s/<token>`) and the website embed URL (`{public_base}/embed/<token>`). For a website widget, paste one line before </body>: `<script src="{public_base}/embed.js" data-token="<token>"></script>`. label names this entry point ("website widget", "support link"). Telegram/WhatsApp and other…
create_skillCreate a skill. description = "when to use" (goes into the system prompt, keep it short); instructions = the detailed guide (fetched on demand via load_skill). The paradigm (important): instructions are visible only AFTER the model calls load_skill — if calling some tool is **mandatory** ("user gives a phone number → must call save_contact"), the trigger must be written into description, otherwise models often answer directly without loading the skill and the rule never takes effect. Also never promise return values a tool doesn't produce (ticket numbers / IDs) — the m…
create_storylineCreate a storyline draft. After creating, self-check with validate_storyline, then publish_storyline. user_visibility — what the end user sees of their own run: "invisible" (default, no UI), "named" (a banner with the storyline name only), "trail" (banner + read-only view where untaken branches and future steps are redacted grey blocks), "full" (banner with step x/y + full read-only map). `learner_visibility` is the deprecated old name (legacy values hidden/completed_only still accepted and mapped). concurrency — who the progress follows: "user" (default) = progre…
diagnose_promptRead a field and return a list of **specific** improvement suggestions (string array). field: same values as improve_prompt. current = the text to diagnose (required — an empty text has nothing to diagnose). Typical flow: diagnose_prompt first, pick the suggestions you want, then fold them into improve_prompt's hint.
export_storylineExport a portable storyline JSON (schema_version + definition; no tenant/version/id) for backup, migration or re-import.
get_agentGet one agent's full configuration (soul/task/tools/skills/knowledge_bases/model/params).
get_end_userGet one end user's detail: basic profile (name, contact email/phone, city, timezone) + their spaces. Never any conversation content. Carries a `console_url` to the user's detail page.
get_knowledge_baseGet one knowledge base's configuration (including the full instructions text shown to the model).
Show 35 more tools
get_knowledge_indexShow the structured index profile: per column coverage, type, numeric range, top values, warnings. **The warnings are the point.** On a real 4,500-document catalogue this surfaced three data problems nobody knew about: 1,058 documents with `page_count` 0, 505 with `reading_level` 0, 493 with `word_count` 0 — those are not zeros, they are missing values recorded as 0, and they silently poison every average, minimum and range filter built on them. Report the warnings to the user in their own terms ("493 of your books have no word count — they will all tie for shortest")…
get_skillGet one skill's full content (including the complete instructions text).
get_storylineGet one storyline's full definition (whole graph + profile_schema + top-level fields).
import_storylineImport an exported storyline JSON as a draft. **Artifacts like "generate a storyline from a novel / source material" land here.** payload = the structure returned by export_storyline (schema_version + graph + profile_schema + top-level fields). Version-aware: payloads newer than the system supports are rejected. Always creates new, never claims default, key collisions auto-rename. override_agent_name rebinds the imported line to an agent that exists in the target tenant.
improve_promptRewrite a field's text to work better as an AI system prompt; returns the improved text. field ∈ persona | task | greeting | storyline_task | storyline_opening | storyline_ai_trigger | storyline_ai_criteria | skill_description | skill_instructions | kb_description | kb_instructions — determines the rewrite target (a Task should read like commands, a KB description says "what's inside / when it's relevant", a skill description says "when to use" in one line, …). current = the current text (empty = draft from scratch); hint = the direction you want this …
list_agentsList all agents in this tenant (name + published state).
list_end_usersList this tenant's **end users** (the people chatting with your agents) — roster only, never any conversation content. Each user carries: display name, login method (email / oauth:* / proxy), email (if any), space/session/document counts, last-24h token usage, and a `console_url` (click through for detail). q filters by name or external id; sort ∈ recent (default) | tokens24h (descending 24h usage). Pagination: pass the returned next_cursor back as cursor. Typical: list_end_users(sort="tokens24h") to find the most active / most expensive users.
list_knowledge_basesList this tenant's knowledge bases (with doc/chunk counts and relevance cutoff).
list_mcp_serversList the MCP servers connected in this tenant's tool library (read-only; secret fields omitted).
list_page_contextsList all page playbooks of this tenant (with match rules, greeting mode, position).
list_sharesList an agent's shares (token / label / disabled / chat link / embed URL / appearance config). When the top-level `pretty_url` is non-empty it is the preferred link to give humans (see create_share).
list_skillsList this tenant's skills.
list_storylinesList this tenant's storylines (optionally filtered by agent). Includes state, version, default flag.
list_toolsList tool names assignable to agents, with their descriptions (incl. the tenant's connected MCP tools).
list_user_sessionsList one end user's **sessions** — metadata only: agent, title (AI summary), message count, tokens, timestamps. **Message bodies are not returned.** Transcripts are rendered in the console: each session carries a `console_url` that **deep-links straight to that conversation, auto-opened** (no digging through the detail page when there are many), plus `user_console_url` to the user's detail page as the general entry. Hand the link to the tenant — a human reads the original there. Pagination: pass next_cursor back as cursor.
page_context_statsOpen counts and suggested-question click counts per playbook — find copy nobody clicks.
patch_knowledge_indexChange the structured index schema from one sentence of plain language. Example requests: "also track the author so users can find other books by them", "I want to filter by illustrator", "drop the cover link". The model may only emit add/modify/remove/refused — it cannot rewrite the table, so it has no way to damage columns the user did not mention. **Data that is not in the documents comes back in `refused`, not as a new column.** Asked for a publication year that the corpus does not carry, it says so instead of inventing an empty column. Pass that refusal on to the…
preview_planGenerate a plan for a goal and return it for review **without persisting anything** — no temporary storyline, no enrollment, no user affected. Use it to inspect plan quality before trusting the feature in production, or to see how the agent's `task` constrains the steps. Returns {plan, backend, warnings}. `warnings` flags machine-detectable smells, notably checklist items that are the AGENT's own deliverable ("produce a summary") — those can never be ticked off, because ticking is judged from what the USER provides, so the step would stall forever.
publish_storylinePublish a storyline: validates first (blocking errors → 422), then freezes an immutable version and marks it published.
resolve_page_contextGiven a URL (or key), show which playbook it resolves to — always verify after writing a match rule. Globs make it easy to write rules that "look right but never match" (one `*` short, one path level too many) — and in production the only symptom is visitors silently getting the default playbook, with no error anywhere.
search_agent4_docsSearch agent4.io's own product docs — concepts (what a thing *is*) and cookbook recipes (which tool to *call*). Use when you're unsure how an agent4.io feature works, what a term means, or how to build something on the platform. Returns top passages with title, layer ("concept"|"ops"), url and a snippet. Public content; no tenant data involved.
search_knowledge_baseSearch this knowledge base; returns matching chunks with distances. Uses **exactly the same retrieval path as real conversations** — use it to validate the cutoff and chunking: an empty result means this question will be judged "not covered" and the agent will answer "not in the knowledge base".
set_custom_domainBind the client's own domain to this tenant's chat pages: `https://chat.client.com/` serves the tenant's branded page (or a specific agent's chat), the address bar keeps the client's domain, and the TLS certificate is issued automatically. **Have the client configure DNS first**: add a CNAME at their DNS provider pointing to the `cname_target` in the response (`endpoint.agent4.io`). Key points: - **Subdomains only** (`chat.client.com`). An apex domain (`client.com`) cannot carry a CNAME — have the client use a subdomain, or a DNS provider with CNAME flattening (Cloud…
set_pwa_brandingConfigure a specific **agent's** PWA branding and install experience (applies to that agent's `/s/` standalone chat pages — what gets installed to the home screen is one agent's entry page, so each agent is its own app). - `agent`: the agent name whose install branding to configure (required). - `icon_source_url`: public URL of one master image (PNG/JPG/WebP ≥192×192, ideally a square logo). The server derives the full set: browser-tab favicon(48) + install icons 192/512 + Android maskable(512). Non-square images are centre-cropped. Once set, "Add to Home Screen" …
tenant_infoThis tenant's basic info and quota (plus custom-domain binding status, if any).
test_planner_triggerDry-run the Dynamic Planner's escalation judge: would these messages be offered a step-by-step plan? Use it after editing the agent's `task`, since the task text is the **business-domain gate** — a vague task lets out-of-domain requests through, a narrow one turns real customers away. messages: the user's turns in order; the LAST one is treated as the current turn and the rest as that user's earlier messages (same window the live judge sees). samples>1 re-runs the judge to show stability (it is a probabilistic call). expect: pass true/false to get `matched`. Nothin…
test_skill_triggerReality-check whether your prompts actually trigger tool calls (dry-run) — run this after writing/changing a skill instead of counting corpses in production. Replays your messages N times against the **production** system-prompt assembly, tool schemas and this tenant's actual model routing, capturing only the model's tool-call decision: **tool side effects are NOT executed**, no session is stored. Tokens count toward the tenant quota (messages≤5, samples≤5, at most 25 calls per invocation — pick test messages carefully). Two modes for the skill's two battlefields: …
unpublish_storylineUnpublish (archive): no more auto-enrolment; in-flight users silently degrade to the plain agent on their next turn (progress kept — re-publishing resumes it).
update_agentUpdate **part** of an agent — fields you don't pass stay as they are. ⚠️ List-field semantics, don't mix them up: `tools=[...]` / `skills=[...]` / `knowledge_bases=[...]` are **full-list replacement** — items you didn't read first get pushed out. To "add one / remove one", use `add_tools` / `remove_tools` (and add_/remove_skills, add_/remove_knowledge_bases): incremental, idempotent, leaves the rest untouched. After the call, **read the response** to verify the final list — don't announce "enabled" just because the call succeeded. Also: tools can ride on a skill (…
update_knowledge_baseUpdate part of a knowledge base — fields you don't pass stay as they are (server-side PATCH merge).
update_skillUpdate part of a skill — fields you don't pass stay as they are (server-side PATCH merge, no GET+PUT round-trip). ⚠️ `tools=[...]` is **full-list replacement**; to add/remove one use `add_tools`/`remove_tools` (incremental, idempotent). Tools bound to a skill take effect automatically at chat time on any agent the skill is attached to — no need to also add them to the agent's tools.
update_storylineUpdate **part** of a storyline draft — fields you don't pass stay as they are (GET-then-merge on top of a full PUT underneath). concurrency: "user" = progress belongs to the person (shared across sessions); "session" = progress belongs to the case (one run per session). Changes affect only **future** enrolments; in-flight runs are not migrated. ⚠️ Especially `graph`: not passing it = keep the existing graph. (This tool once treated "no graph" as replace-with-empty — renaming a storyline wiped its whole flow. Semantics are now partial; to truly clear the graph, pas…
upsert_page_contextCreate or fully replace a page playbook. `context` is the page background the **server** injects for the agent — write "who lands on this page, what they are deciding, what they usually worry about"; do NOT write facts like prices or quotas (those belong in a knowledge base, which also ranks higher in authority). `url_pattern` is a glob (`*/pricing`, `*/solutions/*`), matches the path only, ignores query strings and trailing slashes; without it the page must report the key explicitly. Resolution order: explicit key > url_pattern > default. `greeting_mode="generate…
usage_statsUsage statistics. group ∈ total | agent | user | space | day | model. Metadata only — token counts and event counts, never any conversation content. Use group="user" to see who uses the most, group="agent" for the busiest agent.
validate_storylineValidate the storyline graph (entry / dead ends / unreachable / dangling / cross-line targets / rule dimensions). Returns {ok, errors}. Must pass before publishing.
