api record

Toolpin reports observed facts about MCP servers in the public registry: whether a server answered when we last probed it, what its tools claimed to do, and whether that claim has changed. Every field comes with the time it was observed. Nothing here is a score, a rating, or a safety judgment, and no result should be read as one. Change counts arrive with the catalog base rate because drift concentrates in servers nobody depends on: compare a server against that rate before concluding anything about it.

_ used through this hub 30 days

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.

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.

  • search_servers unknown never probed

    Find MCP servers in the public registry by name or title. Returns the canonical name, description, and whether the server answered our last probe. Use this to turn a rough idea of a server into the exact name the other tools need.

    mcp-tool

    {
  "type": "object",
  "title": "search_serversArguments",
  "required": [
    "query"
  ],
  "properties": {

  • get_server unknown never probed

    Everything Toolpin has observed about one MCP server: reachability of each remote endpoint and when each was last checked and last verified, repository activity, the current tool-definition hash, and how many changes it has recorded in the last 90 days. The reply includes the catalog-wide drift rate so that count can be read against a baseline.

    mcp-tool

    {
  "type": "object",
  "title": "get_serverArguments",
  "required": [
    "name"
  ],
  "properties": {
    "name": {
      "type": "string",
      "title": "Name"
    }
  }
}
    arguments 13 lines
  • get_server_tools unknown never probed

    The tool definitions one MCP server advertised when Toolpin last read them, each with a SHA-256 hash of the fields the MCP specification defines. Use this to see what a server's tools claim to do without connecting to it, or to compare a hash you pinned earlier.

    mcp-tool

    {
  "type": "object",
  "title": "get_server_toolsArguments",
  "required": [
    "name"
  ],
  "properties": {
    "name": {
      "type": "string",
      "title": "Name"
    }
  }
}
    arguments 13 lines
  • get_server_changes unknown never probed

    Changes Toolpin recorded for one MCP server: tool definitions changing, and endpoints going down or coming back. Each change says which tools moved and which of their fields differed, with the hash before and after. Includes the catalog-wide drift rate for comparison.

    mcp-tool

    {
  "type": "object",
  "title": "get_server_changesArguments",
  "required": [
    "name"
  ],
  "properties": {
    "days": {
      "type": "integer",
      "title": "Days",
      "default": 90
    },
    "name": {
      "type": "string",
      "title": "Name"
    }
  }
}
    arguments 18 lines
  • get_spec_status unknown never probed

    The current MCP specification revision, which of its proposals Toolpin checks for, and how much of the catalog has migrated. Use this to find out what the current revision is and how unusual it is to still be on an older one.

    mcp-tool

    {
  "type": "object",
  "title": "get_spec_statusArguments",
  "properties": {}
}
    arguments 5 lines
  • watch_server unknown never probed

    Start monitoring an MCP server on the caller's Toolpin account, so they are emailed when it changes or stops answering. Needs an API key. Says so plainly if the account is already at its plan limit rather than failing.

    mcp-tool

    {
  "type": "object",
  "title": "watch_serverArguments",
  "required": [
    "name"
  ],
  "properties": {
    "name": {
      "type": "string",
      "title": "Name"
    }
  }
}

_ 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.
