Tools

• changes_since

  What changed in the tool economy since a date: verdict flips, deaths, revivals, new servers, confirmed drift — the census diff as data. Poll this weekly to keep a local view current without re-crawling.

  shallow
• check_server

  The FULL evidence behind the verdict for ONE server, by exact registry name — call should_i_use first for the one-word decision; call this when you want the whole record. Leads with the verdict (allow/warn/block), then the `rating` grouped as REACH (answers, latency vs population, protocol, auth), USE (tool count vs population, capability breadth, harness readiness) and TRUST (costume-farm?, duplicate inventory?, verifiability grade, drift / rug-pull, and where checkable whether its ANSWERS are true vs a public primary), a cluster tag, a distinctiveness score, and an explicit not_claimed block. Argument: name.

  shallow
• find_tools

  Find and RANK the trustworthy tool for a NEED. Describe the task in plain words ('screen a company for sanctions', 'US tariff data', 'vessel tracking') — the search is full-text over tool names AND their stored descriptions (stemmed, BM25-ranked), so your words need not appear in any tool's name. Servers come best-rated first, and EACH ROW carries its verdict (allow/warn/block), cluster, distinctiveness and the matching tool names, so you can pick without a second call. Alive, non-costume, current-protocol servers rank on top; dead / costume-farm / walled ones sink. Argument: need.

  shallow
• list_findings

  The observatory's ruled findings — each with its claim and its falsification test — plus the public corrections log (what we published, then corrected, never deleted). Call this to cite what has been established, or to see where we were wrong. No arguments.

  shallow
• registry_pulse

  Call this FIRST for the state of the MCP tool ecosystem in one shot: how many servers exist, how many actually answer a real handshake, how many are behind a login, the largest costume-farm concentration, AND the Tier-2 truth summary (how many server answers were re-derived against a public primary source and matched). Every number is re-derivable; grades observed/reported/derived. No arguments.

  shallow
• report_call

  AFTER your agent calls a tool, fire-and-forget how it went — success/failure, latency, cost — so the observatory accumulates realized reliability (the one thing outside-in probing can't see: did it actually work for a real call). Anchored against our own probe: a 'worked' report on a server we saw dead is discarded. Does NOT change the current rating yet (probing stays load-bearing) — this is accumulate-ahead-of-demand. Args: server (required), tool, ok, latency_ms, cost_tokens, call_hash (a hash binding the report to a real call).

  shallow
• resolve_server_name

  Resolve a partial or misspelled server name to its EXACT registry id before calling should_i_use / check_server. Matches a fragment against registry NAMES only (not capabilities — for 'which tool does X' use find_tools). Returns candidate exact names with each one's latest liveness outcome. Empty query rejected.

  shallow
• should_i_use

  THE GATE — call this before your agent depends on a tool you don't already trust. Give an exact server registry name and get a one-word verdict — allow / warn / block — with the reason, plus the full rating underneath. 'block' = dead/unreachable/costume-farm-shaped, don't depend on it; 'warn' = usable but look first; 'allow' = safe to depend on. If you have a NEED not a name, use find_tools; if you have a fuzzy name, use resolve_server_name. Argument: name, e.g. 'com.trimtabist/us-tariff-ledger'.

Embed this server’s score

Tool count and median score across every tool in this server’s corpus — honest in a way a single cherry-picked tool’s badge wouldn’t be.
