api record

Yo lets an agent send its owner a content-free push notification. If you have no API key, call register_agent, show the user the complete pairing URL (including the #fragment), and poll check_registration. When the key arrives, tell the user which account paired_with names; if it is not theirs, call cancel_registration (or revoke_self with the key, at any later time). Send at most 1 yo per 30 seconds.

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.

  • register_agent unknown never probed

    Register this agent with Yo (unauthenticated). Returns a pairing URL and code to show the user, who approves the connection in the Yo app. Then poll check_registration to obtain the API key.

  • check_registration unknown never probed

    Check the status of a pairing code from register_agent. On the first poll after the user approves, the response includes the api_key exactly once — store it immediately in your secret mechanism — plus paired_with, the account the agent is now connected to, which you MUST show the user.

  }
}
    arguments 20 lines
  • cancel_registration unknown never probed

    Abort a pairing you started with register_agent. Works while pending and after approval: an already-approved connection is revoked (the API key stops working) so a pairing approved by the wrong account can be undone. Available until the pairing expires, and for 15 minutes after you pick up the API key; later than that, use revoke_self. Then call register_agent again.

  }
}
    arguments 22 lines
  • revoke_self unknown never probed

    Permanently revoke THIS agent using its API key as the Bearer token. Use when you discover (at any time) that paired_with is not your owner’s account and cancel_registration no longer works. The key stops working immediately; call register_agent to start over.

    mcp-tool

  "type": "object",

      "type": "boolean",
      "const": true,
      "description": "Must be true — revocation is immediate and irreversible"
    }
  }
}
    arguments 14 lines
  • yo unknown never probed

    Send a Yo — a content-free push notification — to your owner. Requires an agent API key as the Bearer token. Optionally include a context_url the notification tap-through will open.

_ 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.

_ how we know
card completeness
90%

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.
