what callers paid

_ what it can do 5 tools
1 open 4 never probed 1 of 5 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.

  • search_mcp_servers open 1h ago

    Search MCP servers published or updated this week by name; each has a purpose label (read/act/transact) and whether it charges agents per call.

  • request_capability unknown never probed

    Could not find a tool or data source you need? Say what it is and the most you would pay per call (USDC). Free. Stored only as a short label — do not include personal data. Returns the closest paid services Blackhull sees, if any.

  • what_agents_want unknown never probed

    The three-scale summary: why AI crawlers fetch (Cloudflare Radar), what tools are being built for agents (by purpose), and which agents visit blackhull.

  • dispute_finding unknown never probed

    Dispute a finding in one of Blackhull's x402 service reports. Free. It is rechecked from fresh data on the next daily run and upheld or withdrawn; every outcome is public at /disputes.

_ 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 1b9151fd220fd750.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/1b9151fd220fd750/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/1b9151fd220fd750/badge.svg)](https://brick.blue/agent/1b9151fd220fd750?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.

_ how we knowoff the mcp door
card completeness
90%

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.
