_ is it live, free and safe measured by this hub
Is crawlgraph live?
Yes — it answered the hub's last check (checked 3h ago). It answered 99% of checks over the last 30 days.
Is crawlgraph free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does crawlgraph have?
5 tools: backlink_changes, backlinks, gap_analysis, gap_outreach_targets, releases.
Is crawlgraph safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

_ what it can do 5 tools

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.

  • releases reads auth-required 17h ago

    List the Common Crawl releases the API can query. Does not count against any quota. Use a release `id` with the backlinks tool to query a specific snapshot.

    mcp-tool

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • backlink_changes reads unknown 17h ago

    Compare referring-domain observations between two Common Crawl releases. When from_release and to_release are omitted, the API chooses the newest queryable release pair. Costs one backlinks call against the monthly quota. A removed domain means it was not observed in the newer Common Crawl snapshot, not that deletion from the live web has been proven. comparison_available: false is a valid successful response when two queryable snapshots do not exist.

  • backlinks reads unknown 17h ago

    Look up referring domains (backlinks) for a single target domain from the Common Crawl webgraph. Returns each linking domain with host count and CrawlGraph authority score, plus the target's own authority/rank. Costs one backlinks call against the monthly quota (1,000/mo for lifetime or eligible monthly paid access). These snapshot observations do not prove live links.

  • gap_analysis reads unknown 10h ago

    Run a competitor backlink gap analysis: find domains observed linking to one or more of your competitors but NOT to you. Submits an async job and polls until done (usually 5-30s). Returns every gap with `found_on` listing which competitors each domain was observed linking to. Costs one gap job against the monthly quota (50/mo for lifetime or eligible monthly paid access). These observations do not prove live links.

  • gap_outreach_targets reads unknown 10h ago

    The warm-outreach play. Runs a gap analysis, then ranks results: PRIORITY = domains observed linking to ALL your competitors but not you (research candidates, without proof of live links or publisher awareness), SECONDARY = domains observed linking to 2+ competitors. Platform/CDN noise is filtered, top N priority targets are scored by authority. Use 2-3 competitors. Costs one gap job + one backlinks call per enriched target.

_ 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 50212a22e5c884bb.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/50212a22e5c884bb/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
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.
