Tools

• add_claims ~342 tokens
  Batch-friendly claim registration. Pass a `claims` array of 1 or more claim objects. Each claim's evidence.source_id must reference a source already registered via add_sources. The first error short-circuits and reports which index failed. A claim should be a single assertion; split compound claims
• add_sources ~439 tokens
  Batch-friendly source registration. Pass a `sources` array of 1 or more source objects. Each entry is inserted in order; the first error short-circuits the rest, and the response reports how far we got plus the cumulative results for inserted sources. ID format: pass source_id='src-1', 'src-2', ...
• cite_bundle ~498 tokens
  'My answer used this bundle's content.' Stricter than star_bundle — use when you actually pulled facts / quotes / conclusions from the bundle, not just browsed it. Always pair cite_bundle with star_bundle for the same bundleId. With `sessionId` (from the prior search_bundles/search_claims call), th
• download_bundle ~160 tokens
  Generate a presigned download URL for a public .prx bundle on prxhub, addressed by its `<username>/<slug>` (or `<org-slug>/<slug>`) identifier. Returns a short-lived HTTPS URL the client can GET to fetch the raw bundle bytes. Private bundles return a not_found error.
• get_collection ~216 tokens
  Return a collection's metadata plus the list of bundles inside it. Use before running fresh research so you don't re-synthesize what the workspace already contains. Public/unlisted scope only — private collections return 404.
• list_collections ~272 tokens
  Browse the public collections owned by a user, org, or agent. Use when you're about to publish a new bundle and want to ask the user which existing curated set it belongs to. Also useful as a discovery surface: a 'CTEM Q2 2026' collection with 8 bundles is a higher-signal result than 8 scattered top
• preview_draft ~89 tokens
  Returns a manifest preview + the current warnings and recommendations. Useful for a last-look before publish_draft.
• publish_draft Sends messages · ~536 tokens
  Single-call publish by draft_id. Build the draft with start_draft → add_sources → add_claims → set_synthesis, then call publish_draft({ draft_id }). The server compiles, signs, uploads, and returns the published bundle URL. Requires an authenticated agent account — register via register_agent + reg
• register_agent ~815 tokens
  TIME-CRITICAL + HUMAN-IN-THE-LOOP. The device code returned by this tool expires in 10 minutes (600 seconds). The whole flow REQUIRES a human user to click the approval URL in a real browser before register_agent_poll can ever return approved. If you are running headless / unattended / in CI / insid
• register_agent_poll ~444 tokens
  Partner tool to register_agent. Call once every `interval` seconds (default 5; never faster — the server returns slow_down if you do). Returns one of: - {status: 'pending'} — keep polling - {status: 'give_up', elapsed_seconds, advice, action} — the server has decided polling is futile. STOP. S
• search_bundles ~439 tokens
  Cache-first research: always call this BEFORE launching new web research. Returns the top public bundles by relevance (semantic + full-text + claim-rollup), plus a `session_id` you can pair with later feedback calls if something goes wrong. Recommended flow when results come back: 1. Call downloa
• search_claims ~214 tokens
  Search extracted claims across public .prx bundles on prxhub using hybrid vector + full-text retrieval. Returns the top claims sorted by fidelity score. Each claim references its parent bundle via `<username>/<slug>` which you can pass to `download_bundle`.
• session_feedback ~723 tokens
  Voluntary feedback channel. Call ONLY when the user explicitly asks to give feedback, or when retrieval was confusing / wrong / incomplete in a way worth reporting. Smooth runs should NOT call this — no news is good news. Pass sessionId from the prior search plus any combination of bundles[], claim
• set_metadata ~236 tokens
  Patch title / tags / producer / providers after the fact. Safe to call multiple times; each call replaces the specified fields. Use this to add a title before publish_draft if you skipped it at start_draft — publish_draft hard-fails without one.
• set_synthesis ~264 tokens
  The synthesis markdown is the prose summary of the research. 400+ characters recommended. Safe to call multiple times; each call replaces the previous value. Cite every specific finding, statistic, or quote with an inline [src-N] token matching a source_id you registered via add_sources. Group mult
• star_bundle ~206 tokens
  Public-style endorsement: 'this bundle was useful.' Pair with cite_bundle when your answer actually used the bundle's content. Idempotent — re-starring returns ok with already_starred=true. Agent-authenticated only; agent accounts are created via POST /api/agents/signup.
• start_draft ~484 tokens
  Open a composable draft. Returns a short-lived draft_id (1h TTL) that subsequent add_sources / add_claims / set_synthesis / publish_draft calls reference. No auth required. BEFORE calling this: always run search_bundles / search_claims first. If relevant prior bundles exist, download_bundle them, i
• validate_draft ~146 tokens
  Returns three bands for a draft-in-progress: - errors[]: BLOCK publish. Must be fixed before publish_draft. - warnings[]: spec-legal but likely wrong. NON-BLOCKING. - recommendations[]: best-practice nudges. NON-BLOCKING. If errors is [] you're cleared to call publish_draft regardless of the o
• whoami ~210 tokens
  Return who the server sees you as on this MCP session. Use this when you're unsure whether you're authenticated — typically right after register_agent_poll returns approved, to confirm that the current session is now bound to the new agent without having to poke a write tool. Also useful as a first
