_ is it live, free and safe measured by this hub
Is FreshProof live?
Yes — it answered the hub's last check (checked 32m ago). It answered 100% of checks over the last 30 days.
Is FreshProof free to use?
Yes — the hub reached it with no key and no payment.
What tools does FreshProof have?
4 tools: freshproof_info, verify_proof, verify_url, observe_url.
Is FreshProof 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

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 4 tools
4 never probed 0 of 4 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.

  • freshproof_info reads unknown never probed

    Describe FreshProof, its observation semantics, current MCP price and payment network. This tool is free.

  • verify_proof reads unknown 22h ago

    Verify an existing FreshProof Proof Receipt without making a new network request. This free tool checks deterministic receipt integrity and optionally evaluates trust policy rules. Use it when you already have a proof_id from observe_url or verify_url and want to re-check evidence without paying for another observation. The result includes valid, decision (PASS, FAIL, or UNKNOWN), per-rule checks, and the stored receipt.

  • verify_url reads unknown 22h ago

    Verify what is observable at a public URL before an agent trusts, pays, or acts. This paid tool combines observe_url and verify_proof in one call: it buys an observation, creates or returns a Proof Receipt, and evaluates the supplied trust policy. Set max_age=0 when current public-network evidence is required. The result contains both observation evidence and verification with decision PASS, FAIL, or UNKNOWN.

  • observe_url changes data unknown 22h ago

    Buy a timestamped FreshProof observation of a public HTTP/HTTPS URL. Returns final URL, observation timestamp, age, HTTP status, SHA-256 body hash, body size, ETag, Last-Modified, fetch duration, and whether the observation came from shared cache or a fresh public-network request. Set max_age=0 when a new public-network request is required. The response body itself is not returned.

_ try it 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 20a30232bde98ff0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/20a30232bde98ff0/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 know
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.
