api record

Robin Saige rates the tools AI agents call, so you can check one before you depend on it. The core loop: should_i_use(name) = the one-word gate (allow/warn/block) before depending on a tool; find_tools(need) = describe the task in plain words — full-text over tool names AND descriptions, so your words need not appear in a tool's name — each row already carrying its verdict; resolve_server_name(query) = a fuzzy name → exact id; check_server(name) = the full evidence behind a verdict; registry_pulse() = the ecosystem at a glance; list_findings() = ruled findings + public corrections.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 8 tools
1 open 7 never probed 1 of 8 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_findings open 2h ago

    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.

    mcp-tool

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • registry_pulse unknown never probed

    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.

  • should_i_use unknown never probed

    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'.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "name": {

    }
    arguments 17 lines
  • find_tools unknown never probed

    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.

  • resolve_server_name unknown never probed

    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.

    mcp-tool

    {
      "type": "object",
      "required": [
        "query"
      ],
      "properties": {
        "query": {
          "type": "string",
          "description": "a fragment of a registry name, e.g. 'tariff'"
        }
      }
    }
    arguments 12 lines
  • check_server unknown never probed

    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.

    {
      "type": "object",
      "required": [
        "name"
      ],
      "properties": {
        "name": {
          "type": "string",
          "description": "exact registry name, e.g. io.github.you/your-mcp"

    arguments 12 lines
  • report_call unknown never probed

    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).

    mcp-tool

    {
      "type": "object",
      "required": [
        "server"
      ],
      "properties": {
        "ok": {
          "type": "boolean"
        },
        "tool": {
          "type": "string"
        },
        "server": {
          "type": "string",
          "description": "exact registry name"
        },
        "call_hash": {
          "type": "string"
        },
        "latency_ms": {
          "type": "integer"
        },
        "cost_tokens": {
          "type": "integer"
        }
      }
    }
    arguments 27 lines
  • changes_since unknown never probed

    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.

    mcp-tool

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
