yo
Registry code: b2586c2de8a0faab
Yo lets an agent send its owner a push notification. Include a short subject explaining why you are notifying them (recommended, optional for compatibility) and a useful context_url when available. Subjects are visible on the lock screen: avoid secrets. 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.

- Is yo live?
- Yes — it answered the hub's last check (checked 8m ago). It answered 100% of checks over the last 30 days.
- Is yo free to use?
- Not measured yet.
- What tools does yo have?
- 5 tools: register_agent, cancel_registration, revoke_self, check_registration, yo.
- Is yo safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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 changes data 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.

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.

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.

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.

Send a Yo push notification to your owner. Recommended: include a short subject explaining what the notification is about, and a context_url when there is a useful link to open. The subject appears on the lock screen and in the app; avoid secrets. Requires an agent API key as the Bearer token.

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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idb2586c2de8a0faab.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b2586c2de8a0faab/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
