_ 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 4 tools
4 never probed 0 of 4 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.

  • create_watch unknown never probed

    Start monitoring a web page (or JSON/text URL) for changes. Captures a baseline snapshot now. Returns a watch_id and a token — save the token; it's how you check and manage your watches later. Pass an existing token to add more watches under the same account.

    mcp-tool

    {
  "type": "object",
  "required": [
    "url"
  ],
  "properties": {
    "url": {
      "type": "string",
      "description": "Absolute http(s) URL to monitor, e.g. https://example.com/pricing"
    },
    "label": {
      "type": "string",
      "description": "Optional human label for this watch."
    },
    "token": {
      "type": "string",
      "description": "Optional. Your existing Kestrel token to group this watch with others. Omit to get a new token."
    }
  }
}
    arguments 20 lines
  • check_watch unknown never probed

    Re-fetch a watched page and report whether it changed since the last check, with a short list of added/removed content lines. Updates the baseline to the new content. Call this every time you want the latest status (e.g. each run/heartbeat).

    mcp-tool

    {
  "type": "object",
  "required": [
    "watch_id",
    "token"
  ],
  "properties": {
    "token": {
      "type": "string",
      "description": "The token returned by create_watch."
    },
    "watch_id": {
      "type": "string"
    }
  }
}
    arguments 16 lines
  • list_watches unknown never probed

    List all watches under your token, with per-watch check/change counts.

    mcp-tool

    {
  "type": "object",
  "required": [
    "token"
  ],
  "properties": {
    "token": {
      "type": "string"
    }
  }
}
    arguments 11 lines
  • delete_watch unknown never probed

    Stop monitoring a page and delete the watch.

    mcp-tool

    {
  "type": "object",
  "required": [
    "watch_id",
    "token"
  ],
  "properties": {
    "token": {
      "type": "string"
    },
    "watch_id": {
      "type": "string"
    }
  }
}
    arguments 15 lines
_ 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.

[![measured by brick.blue](https://brick.blue/api/v1/agents/672e00f878d2496d/badge.svg)](https://brick.blue/agent/672e00f878d2496d)

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
80%

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.
