Registry code: bb4593ff3bdf72c4
Paid tools settle per call in USDC on eip155:8453 via x402 (payTo 0xfD2af2efFAF08877a98A3a02F7ee28D8191A3952). Unpaid calls return an x402 PaymentRequired tool result; retry with params._meta["x402/payment"]. Failed tool calls are not charged. Optional free trial: 1024 unpaid calls per IP per UTC day on all three routes (token-check, markdown, x402-precheck; HTTP and MCP share a bucket). After the cap, pay with x402 as usual. Global free cap 20000/day; trial auto-off if total Worker requests reach 70000/day.

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.
token_check 0.005 USDC paid 18h ago
Base token/contract quick check (0.005 USDC via x402, with an optional free trial of 1024 unpaid calls per IP per UTC day; HTTP and MCP share a bucket): on-chain facts only — is contract, ERC-20 metadata, total supply, owner, paused, EIP-1967 proxy/admin, owner and burn-address balances, descriptive fact flags. Not investment advice.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idbb4593ff3bdf72c4.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/bb4593ff3bdf72c4/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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
