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 3 doors on this origin, so the chain figures are the operator's.

_ what it can do 4 tools
1 open 3 never probed 1 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.

  • list_chains open 1h ago

    List supported chains (Base, Ethereum, Arbitrum, Optimism, Polygon, Solana) and the gas-unit constants used by the paid tools (free).

  • read_url_as_markdown unknown 1h ago

    Convert any web page into clean, readable Markdown. Fetches a public web page and returns clean Markdown: title, byline, site name, excerpt, word count and the extracted article body. Use it to give an AI agent readable text from a URL without writing your own scraper. Respects robots.txt, blocks private hosts, follows at most five redirects, caps the page at 3 MB. Pass links=true to also get the page's outbound links. Costs $0.003 USDC per call (x402).

  • compare_gas_costs unknown never probed

    Where is it cheapest to send this transaction right now?. Ranks all supported chains by the USD cost of a specific transaction type (transfer, USDC transfer or swap) at a specific speed tier (slow, standard or fast). Returns the sorted ranking, the cheapest chain and any chains that could not be queried. Costs $0.005 USDC per call (x402).

_ 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 fee17eb93aad5f20.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fee17eb93aad5f20/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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
