On 2026-10-30 the server answered initialize and tools/list without a sign-in. First answer in 251 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 4 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• list_projects

  List all projects accessible with this API key. Use this to find project IDs for other tools. **Start here** to discover which projects you can work with.

  List recent structured agent self-assessments for a project. Use this miss log to find recurring missingContext/toolIssues/processGaps and improve project context.

• update_task

  Update task fields like description, implementation plan, priority, effort, quarter, start/due dates, labels, or visibility. Pass status "closed" to discard a task that will not ship. Useful for refining task details as you learn more…

• create_task

  Create a new roadmap task. Use for importing from TODO files or creating work items. When the task comes from customer feedback, pass `feedbackIds` to link it in the same call: the feedback status follows the task and followers are…

• add_note

  Add a note to a task, or resolve a previously reported blocker/open_question. Use ONLY for non-obvious approach decisions and blockers — do not restate commits, checklist confirmations, or self-assessment findings here; those are already…

• add_commit

  Log a commit for a task (secondary detail — the linked pull request is the primary deliverable, see `link_pr`). **When to use:** - After a notable commit: log hash and message - When completing work: optionally pass commits to…

• link_pr

  Link the pull request that delivers this task. The PR is the primary deliverable of a task — call this as soon as the PR exists, and call it again with `state: "merged"` after merge. Upserts by URL, so repeated calls update the same PR…

  Attach a Mermaid diagram that explains the logic or structure behind a change, so the reviewer can follow it without reading the diff. OPTIONAL — add one only when it clarifies something a list of endpoints or screenshots cannot: a…

• list_review_artifacts

  List the API examples, screenshots and diagrams attached to a task, with the reviewer's verdict on each (approved / changes_requested + comment). Use it to check coverage before complete_task, and to find artifacts a reviewer asked you to…

• remove_review_artifact

  Remove an API example, screenshot or diagram from a task, by id or by kind + key (e.g. a page that no longer changes).

• start_task

  Lock and start a task. Fails if locked by another agent unless force=true. Use force=true to take over a task from another agent (e.g., if they abandoned it). Returns project context index with relevant sections for the task. If the…

• review_task

  Optional standalone self-review step. You can also pass `selfAssessment` directly to `complete_task` instead. Reflect on your session: what project knowledge was missing, what tools were confusing, what process gaps caused friction. This…

• complete_task

  Mark task as ready for review (in_review). A human will verify and move it to done. Pass `skipReview: true` to mark as done immediately (use when the human explicitly asks). If the task is already in_review (put there by a previous…

• request_review

  Lightweight hand-off into review: move an in_progress task to in_review as soon as a human could review it (a working slice, an opened PR, attached screenshots or API examples, or when you are about to stop for the session). Do not leave…

• abandon_task

  Release lock and return task to planned status. Works for in_progress and in_review tasks. **Before calling:** 1. Push any WIP commits **Summary parameter:** What was done, what remains, blockers. Helps the next agent.

• list_context_sections

  List available project context sections with brief previews.

• resolve_context

  Resolve touched file paths to governing context sections, critical rules, risk domains, and suggested checklist scope. Uses routing/path-to-context when present and falls back to module paths plus section metadata.

  Get full content of a specific context section. Supports glob patterns for hierarchical sections. **Hierarchical paths**: For monorepos or large projects, sections can be organized hierarchically (e.g., "api/architecture"…

• update_context_section
