Tools 8 found in our last check

  • 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 agai…

  • 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…

  • 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 i…

  • 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 liven…

  • 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 populatio…

  • 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…

  • 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.

  • 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.
