_ is it live, free and safe measured by this hub
Is jurat live?
Yes — it answered the hub's last check (checked 22h ago). It answered 99% of checks over the last 30 days.
Is jurat free to use?
Yes — the hub reached it with no key and no payment.
What tools does jurat have?
8 tools: x402 endpoint pre-flight, Notarized snapshot, Sports scoreboard, Settlement result, Change watcher, Scheduled wakeup, Signed conformance report, Rendered evidence bundle.
Is jurat 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.

_ usage and payments 30 days

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 3 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

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 8 tools
1 paid 7 never probed 1 of 8 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.

  • evidence-bundle 0.75 USDC paid never probed

    Full-page PNG, PDF, raw HTML, and markdown for one public URL, hashed and signed with the attestation key.

  • preflight unknown never probed

    Check any x402 endpoint before paying it: live 402 challenge, advertised price versus charged price, verdict.

  • snapshot unknown never probed

    Signed, timestamped attestation of any public URL.

  • scores unknown never probed

    Normalized scores for 24 leagues incl. rugby + cricket.

  • result unknown never probed

    Final score + notarized source snapshot.

  • watch unknown never probed

    Webhook on change or final whistle, proof attached.

  • wake unknown never probed

    Webhook at time T with stored payload.

  • conformance unknown never probed

    Sweep a whole x402 service, grade it, and return an ed25519-signed report anyone can verify offline.

_ 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 b3e0597d587b44f9.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b3e0597d587b44f9/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
80%

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.
