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.

  • list_capabilities open 1h ago

    Free discovery: price, networks, rule set and list coverage for check_payment_recipient.

  • get_receipt unknown 1h ago

    Free: fetch a stored receipt by receipt_id or idempotency_key. Use it to reconcile an uncertain payment before ever paying again.

  • check_payment_recipient unknown never probed

    Paid ($0.05, x402 v2 exact): pre-signing safety check of a planned payment. Returns allow / escalate / block with reasons, evidence and a verifiable receipt. Input errors are returned before payment and are never charged. On an uncertain outcome, reuse the same idempotency_key; a replay returns the stored receipt without a new payment.

_ 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 19f0a6a8e2e96b2c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/19f0a6a8e2e96b2c/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.
