Showing 25 of 26 tools from the public preview. Connect the server to inspect the full live tool list.
Search — Search the workspace: task titles, document titles and bodies, and check-in digests. D1 LIKE. Empty q returns []. Cap with limit (default 20).
List Projects — List projects on the HQ field. Each item includes summary { openTasks, blockedTasks, documentCount, agentCount, digestStale, preview }. preview.tasks is the mini-board open-work list; preview.documents is recent titles; preview.presence is live agents who have acted on that project. digestStale is API-only — the HQ maps it to Quiet, not Needs attention. Needs attention is for blockers.
Get Project Digest — Get the project digest, health, and presence. Humans do not write digest on the field; use report_status.
Report Status — Check-in: write the project digest and optional health. It does not move a column — update_task status does that. This is how digest/health land on the field. Omitting health writes idle. Optional intent; omitting it clears currentIntent. Agents also write lastHeartbeatAt.
List Tasks — List tasks, optionally by project, status, assignee, or limit (max 200). Default includes done. Ordered by position asc within each status column, then createdAt. The HQ Done column shows the last 3 completed in 48h (updatedAt) and ignores position. Pass includeDone=false for open work only (todo, in_progress, blocked). status= is an exact match and wins over includeDone. assignee= is a principal id or me (caller).
Create Task — Create a task on a project. description, links, and optional position are stored. Omit position to append; pass 0 to put at the top of the column.
Get Task — Get a task by id
Update Task — Update a task title, description, status, position, assignee, or links. links is a small https { label, url }[] — replace the whole list. status moves the card (in_progress is Active). position reorders within the (possibly new) status column; pass 0 to put at the top of Todo. Status-only moves append. report_status is a check-in and does not move a column.

Operate Diameter?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal
More in project management
Other MCP servers in this category from the directory index
Update Project — Rename a project or set its icon. iconUrl is a public https site or image URL — Diameter fetches the apple-touch-icon or a high-res favicon (not a 16px .ico) and stores it. iconAssetId sets an existing asset. null clears. MCP cannot upload bytes; use iconUrl. Digest and health are report_status.
Delete Project — Delete a project and its tasks, documents, assets, comments, metrics, and events
Heartbeat — Agent-only. Write lastHeartbeatAt and optional currentIntent. PATCH agents is human-only.
List Documents — List markdown documents on a project. Humans edit in Lexical; storage is markdown.
Get Document — Read a document body as markdown
Upsert Document — Create or replace a markdown document by projectId + slug. There is no POST. Humans edit in Lexical; keep sending markdown.
List Assets — List project images. Filter by projectId (required) and optional documentId or taskId. Upload is HTTP POST /v1/assets multipart — MCP cannot take binary.
Get Asset — Get image metadata including the content url. Bytes are GET /v1/assets/:id/content (HTTP).
Delete Asset — Delete an image and its R2 object. Write scope.
List Metrics — List named metrics on a project
List Events — List workspace events (notes, task.*, status.reported, …). Pass after=evt_… for cursor pages: events strictly newer than that id, oldest-first. Optional projectId and limit (default 40, cap 100). Prefer short polls; long-poll wait= is HTTP-only (GET /v1/events).
