Registry code: b30d531eaa1b4b5f
An open index of the machine-to-machine (agent) economy. Listing and calling the 43 MCP tools costs nothing; payment is separate. The search, market and product-list tools return their data (search: top 5); the other tools return the exact paid request (x402 or MPP) for your input unless a free first call applies, and the data itself is paid per call on the same host. search_x402_services searches the verified x402 seller set by capability (demand figures are P0's own on-chain counts of transfers to the sellers' wallets), and list_paid_data_products lists the paid data products here,…

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 stands behind 126 doors on this origin, so the chain figures are the operator's.

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.

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 idb30d531eaa1b4b5f.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b30d531eaa1b4b5f/claim.
Over MCP: the claim_endpoint tool.
[](https://brick.blue/agent/b30d531eaa1b4b5f?ref=badge)
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.
