what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly

_ what it can do 2 tools
2 never probed 0 of 2 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.

  • hotel_reserve unknown never probed

    Book a room `list_hotels` priced. Pass the `offerId` that room and rate came back with, exactly as given — it names the hotel, the room, the rate, the stay and the price, which is why none of those are separate arguments. It needs the guest's full name, email, phone and address, so ask for those once they have chosen. It answers one of two ways: a `confirmationNumber` means the room is booked and the guest pays the hotel at the desk, and a `paymentUrl` means the room is not held yet and that link is where the guest pays to get it booked. A handle expires after 30 minutes; call `list_hotels` again with that same `offerId` to re-price the one room rather than searching the whole property afresh. Where a rate's `cancelTerms` is null we hold no cancellation terms: say so, say the hotel's own terms apply and arrive with its confirmation, and book once the guest agrees on that basis. Public — no API key.

  • list_hotels unknown never probed

    Search hotel properties and price them for a stay in one call. Filter by place name and radius, full-text query, country and star rating. Check-in, check-out, party size, `maxPricePerNight` and its `currency` are REQUIRED: ask the guest for the first four before searching, because a call without them runs no search and answers with what is still to be asked. `currency` is the ISO 4217 code of the budget figure (`EUR` most of the time): use the one the guest already named rather than re-asking, and ask them only when they gave a bare number you cannot place. Send their own number and name its currency, never one you converted; every price in the answer comes back in that same currency, named back to you in the answer's own `currency` field — read that rather than assuming one. Ask about children with the party size and pass their ages in `childrenAges` — a child left out is priced as absent, and a child whose age is still `null` is refused until the age arrives. With them the answer comes back in two groups: `priced` holds the hotels whose live rates were read, each room with its price for the stay, its terms and either an `offerId` to book it with or a booking link carrying the guest's dates; `unpriced` holds the rest, each with the property's own website and no booking link. `priced` holds only the hotels and rooms at or under `maxPricePerNight`; when not one hotel fits, they come back in `aboveBudget` with their real prices. An empty `priced` alongside an empty `aboveBudget` means the rates could not be read — unknown, never sold out. A property that told us it is full for the stay is left out of the answer entirely, and `hint` says how many. Public — no API key.

_ 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 b3211d26e1a1aaee.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b3211d26e1a1aaee/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
60%

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.
