what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ 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.

  • book_flight moves money unknown never probed

    Book a quoted flight (legacy pov1 path). Mandate + DPoP proof required. Get the mandate from authority.webmesh.ai request_mandate (mandate_format "pov1", quote_id = this quote_id, merchant_ans = this supplier). Build dpop_proof with the private key whose thumbprint is the mandate jkt: htm POST, htu https://<this host>/mcp/, body hash = base64url(SHA-256 of quote_id). Returns a demo ticket record (not an airline ticket), the SCITT receipt and evidence_bundle, the input for auditor.webmesh.ai audit_transaction. Errors: MANDATE_PARSE_ERROR, MANDATE_REJECTED, DPOP_REJECTED, PAYMENT_REQUIRED, PAYMENT_REJECTED, EVM_SETTLEMENT_FAILED, rate_limited. Verifies (in order): 0. Mandate authority_ans host is the pinned authority 1. Mandate quote_id == this booking's quote_id (quote binding) 2. Mandate signature (Ed25519, signed by the Spending Authority) 3. Mandate audience == this supplier's ANS name 4. Mandate scope route+date matches supplier-side inventory (non-circular check) 5. Mandate max_amount >= selected option's actual price 6. Mandate time window valid 7. DPoP proof was generated by the jkt key for this exact request 8. EIP-3009 on-chain settlement (when GOVWARE_EVM_ENABLED=1, atomic with ticket) Args: quote_id: the quote_id from a prior get_quote call option_id: the specific option to book (required; picks the exact price) mandate: JSON-encoded pov1 mandate (with signature and quote_id field) dpop_proof: compact JWS DPoP proof (from HTTP DPoP: header equivalent) payment_auth: JSON-encoded EIP-3009 transferWithAuthorization (required when GOVWARE_EVM_ENABLED=1; ignored otherwise)

  • get_quote reads unknown 22h ago

    Quote flights for a route and date (legacy pov1 path; one-way). Options come from Duffel test mode when configured, else a synthetic table. Returns {quote_id, trip_id, options: [{option_id, airline, depart_time, arrive_time, duration_min, price, currency}], total, currency, expires_at (10 minutes), supplier_ans, supplier_sig}; supplier_sig is Ed25519 over the JCS of quote_id, trip_id, total, currency, expires_at, supplier_ans. Pass quote_id and option_id to book_flight. x402-gated when x402 is enabled on this agent (see the card's x402 extension): an unpaid call returns an x402 payment challenge. Rate limit: 20 calls, then 1 per 2 s, shared with book_flight and all callers (error rate_limited). For UCP checkout use the REST API at /ucp/v1, not this tool. Args: origin: IATA airport code (e.g. MAD, JFK, LHR) destination: IATA airport code (e.g. SIN, NRT, DXB) date: ISO date string (YYYY-MM-DD) party_size: number of passengers (default 1)

_ try it over mcp 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 1a3344bfd5d0ad3c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/1a3344bfd5d0ad3c/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.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
