api record

CleanExtract reads public web pages for you as clean Markdown. When a task needs the content of a documentation page, article, RFC or other public URL, call clean_extract_outline first (free), then clean_extract with the section ids you need, or with none for the whole page. The first 3 usable extractions are free per caller; after that each usable extraction costs USD 0.05. Failed extractions are never charged.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 2 tools
2 never probed 0 of 2 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.

  • clean_extract reads unknown never probed

    Extract a full page or selected sections from a public URL or raw HTML as clean Markdown, with navigation, scripts and page chrome removed. Use it instead of a raw fetch when a task needs the text of documentation, an article, an RFC or another reference page: in a five-site benchmark the Markdown was 62% fewer estimated tokens than the HTML. Call the free clean_extract_outline first on a long page, then pass only the section ids you need. A call is charged only when it returns usable content; the first 3 usable extraction calls are free, total, then USD 0.05. Uncharged failures name upstream_timeout, upstream_http_error, bot_challenge, js_shell, empty_extraction, or sections_not_found. Recoverable structured data names fallback_used. Every success reports extraction_quality and extraction_content_ratio_band.

  • clean_extract_outline reads unknown 1h ago

    Free outline with section ids, headings, byte sizes, and a fingerprint, without page body text or payment. It never uses the free extraction allowance. Use it first to see what a long page contains and which sections are worth reading. A later clean_extract call can select sections and is charged only when it returns usable content. Uncharged failures name upstream_timeout, upstream_http_error, bot_challenge, js_shell, empty_extraction, or sections_not_found. Recoverable structured data names fallback_used.

_ 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 45e53e9b6463397c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/45e53e9b6463397c/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
60%

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.
