Is registry live?
Yes — it answered the hub's last check (checked 2h ago). It answered 99% of checks over the last 30 days.
Is registry free to use?
Yes — the hub reached it with no key and no payment.
What tools does registry have?
3 tools: Merchant discovery, Reservation booking (async), Transaction-verified feedback.
Is registry 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.

what callers paid

_ 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.

  • merchant_discovery unknown never probed

    Filter-based search over the restaurant registry (search_merchants), full per-merchant signal dumps with per-field provenance and raw transaction-verified feedback (get_merchant), and honest registry self-description including staleness (get_registry_meta). Never ranked: deterministic, documented ordering only. Reads are free and keyless. Current coverage: 168,524 real merchants across Hong Kong (31,676), Los Angeles, CA (26,754), Tokyo (110,094), plus 500 sandbox test merchants.

  • booking unknown never probed

    Async table reservations: get_availability (honest v1 — availability is confirmed at booking time, not held live), place_booking, get_booking_status (poll or callback_url webhooks), modify_booking, cancel_booking. Bookings are accepted only for phone-verified bookable merchants. Real-merchant fulfillment is NOT live yet: place_booking on a real merchant returns the structured rejection 'fulfillment_not_live'. The full booking loop is testable end-to-end against sandbox merchants (deterministic outcomes, never a real phone call). Copy-pasteable walkthrough with live sandbox ids and forced test outcomes: https://mercantry.org/demo.

  • verified_feedback unknown never probed

    submit_feedback: report how a confirmed reservation actually went — accepted only against a confirmed booking_id, once per booking, within 14 days. Served raw to all agents via get_merchant; never editorialized, never scored.

_ try it over a2a 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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 842ac2512121898f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/842ac2512121898f/claim. Over MCP: the claim_endpoint tool.

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.

_ how we knowoff the mcp door
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.
