api record

CitedBy checks whether a website can be found and cited by AI assistants and search engines. Every tool is read-only and free. check_page fetches one page as CitedBot (robots.txt respected) and lists what to fix, with the fix. check_ai_crawler_access says which AI crawlers a site lets in. check_llms_txt reads /llms.txt. backlinks lists the domains that link to a site, from Common Crawl open data. A whole-site audit with every page needs a plan at https://citedby.eu/plans.

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 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.

  • check_page unknown never probed

    Fetch one public web page as CitedBot (robots.txt respected) and return what is wrong with it for AI answers and search: title, description, headings, structured data, canonical, language, links and more. Each finding has why it matters and the exact fix. Deterministic checks only; says so when the page cannot be fetched.

  • backlinks unknown 1h ago

    How many other domains link to a domain, and the strongest referrers, from the Common Crawl domain web graph. Covers domains with 100 or more referring domains under .eu, EU and UK country domains, plus the 5,000 most-linked sites; says plainly when a domain is not in the data.

  • check_ai_crawler_access unknown 1h ago

    Read a site's robots.txt and test the server for GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, Bingbot and Googlebot. Returns, per crawler, whether robots.txt allows it and whether the server answers it, so you can see who is blocked and by what.

  • check_llms_txt unknown 1h ago

    Fetch /llms.txt of a site and report whether it exists, whether its links work, and whether /llms-full.txt exists. When there is none, the full report holds a draft built from the site's own pages.

_ try it 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 86d86d2610945078.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/86d86d2610945078/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 know
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.
