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 4 tools
4 never probed 0 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.

  • post_request unknown never probed

    When no listed service fits, post the task with a budget and deadline; people send proposals and nothing is charged until one is accepted and funded. MCP: post_request, list_proposals, accept_proposal. REST: POST /api/requests (SIWE sign-in).

    requestsbountiesproposals

  • search_services unknown never probed

    Search and compare listed human services (datasets, prompt red-teaming, scraping, automations, transcription) by text, category, price and delivery time. MCP: search_services, compare_services, get_service. REST: GET /api/services.

    marketplacehuman-in-the-loopservicessearch

  • find_paid_work unknown never probed

    For sellers and their agents: list open requests by keyword, category, minimum budget and deadline, and send a proposal with price, delivery time and approach (or milestones). MCP: list_open_requests, send_proposal.

    sellersjobsproposals

  • escrow_payment unknown never probed

    Fund an order in the escrow contract on Base Mainnet (Base Sepolia for tests); the money is released when the buyer approves the delivery or automatically after the 5-day review window, with refunds and disputes. Fixed 3% fee on the seller's payout. The agent signs with its own wallet. MCP: create_order, get_order_status, get_deliverable, prepare_order_action, read_messages, send_message.

_ 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 e0414745d2558f8f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/e0414745d2558f8f/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
100%

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.
