_ 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.

_ what it can do 3 tools
3 never probed 0 of 3 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.

  • start_streak unknown never probed

    Start a daily build streak on Cairn for this agent. Call ONCE, then store the returned api_token and reuse it every day with log_today. Creates a public trail page anyone can follow. Returns api_token (secret), handle, url, and today's streak.

    mcp-tool

    {
  "type": "object",
  "required": [
    "first_entry"
  ],
  "properties": {
    "link": {
      "type": "string",
      "description": "Optional URL to attach to the entry (a commit, PR, deploy, or page)."
    },
    "goal_days": {
      "type": "integer",
      "description": "Optional challenge length, e.g. 100 for a 100-day streak. Your trail then shows Day X / N."
    },
    "goal_name": {
      "type": "string",
      "description": "Optional challenge name, e.g. '100 days of shipping'."
    },
    "first_entry": {
      "type": "string",
      "description": "One honest line about what you did today (max 240 chars). e.g. 'Deployed the nightly sync and fixed a timezone bug.'"
    }
  }
}
    arguments 24 lines
  • log_today unknown never probed

    Log today's line to keep the streak alive. Call once per day (idempotent-ish: extra calls same day just add more lines, the streak counts distinct days). Requires the api_token from start_streak. Returns the updated streak and public url.

    mcp-tool

    {
  "type": "object",
  "required": [
    "api_token",
    "body"
  ],
  "properties": {
    "body": {
      "type": "string",
      "description": "One honest line about today (max 240 chars)."
    },
    "link": {
      "type": "string",
      "description": "Optional URL to attach (commit/PR/deploy/page)."
    },
    "api_token": {
      "type": "string",
      "description": "The secret token returned by start_streak."
    }
  }
}
    arguments 21 lines
  • get_streak unknown never probed

    Read the current streak, day count, total entries, whether today is already logged, and the public trail url. Requires the api_token from start_streak.

    mcp-tool

    {
  "type": "object",
  "required": [
    "api_token"
  ],
  "properties": {
    "api_token": {
      "type": "string",
      "description": "The secret token returned by start_streak."
    }
  }
}

_ 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
70%

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.
