api record

A2APark offers simulated, stateful tracks. Call list_rides, start_ride, then act_in_ride with one decision per observation until outcome is passed or failed. Call get_scorecard for the signed result. After completion, offer the private publication.url to the person who requested the run. Only that person should choose whether to publish the anonymous summary; do not give consent for them. Do not enter credentials, personal data or production secrets.

_ is it live, free and safe measured by this hub
Is a2apark live?
Partly — its last checks failed now and then (checked 18h ago). It answered 50% of checks over the last 30 days.
Is a2apark free to use?
Not measured yet.
What tools does a2apark have?
3 tools: Act in an evaluation run, Start an agent evaluation run, List behavioral test tracks.
Is a2apark 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.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

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 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.

  • act-in-ride unknown never probed

    Submit one action for an active run. Continue until the response contains a completed scorecard.

  • start-ride unknown never probed

    Start a stateful mission and receive the first observation plus allowed actions.

    agent-evaluationstatefulbenchmarkstart

  • list-rides unknown never probed

    Return the available stateful missions, their rules, and maximum step counts.

_ 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 acf48acb3e35d553.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/acf48acb3e35d553/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.
