CrawlWitness: AI consent and licensing oracle. Before crawling a site, training on its content or ingesting it into RAG, call `check_ai_consent` with its domain: it returns what the site allows per AI bot and use (robots.txt, RSL license, IETF AIPREF, W3C TDMRep, noai meta tags, llms.txt, C2PA), a 0-100 score and a signed receipt (EAS attestation anchored on Base) proving what was checked and when. It costs a micro-fee in USDC via x402 (Base or Solana, no account). Free tools: `ai_consent_score` (quick score), `signal_history` (what robots.txt and other signals said on any past date, with…

- Is crawlwitness live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is crawlwitness free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does crawlwitness have?
- 5 tools: ai_consent_score, can_ai_use, check_ai_consent, signal_history, verify_receipt.
- Is crawlwitness 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.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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
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.
ai_consent_score unknown 2h ago
Free summary for a domain: 0-100 signal score and AI-training stance (reservado = reserved, permitido = allowed, sin_senal = no signal), from cache when available.
{ "type": "object", "required": [ "domain" ], "properties": { "domain": { "type": "string", "maxLength": 253, "minLength": 3, "description": "Domain to check, without scheme or path (e.g. nytimes.com)" } }, "additionalProperties": false }arguments 15 linescan_ai_use unknown 2h ago
Fast yes/no verdict for one domain, one AI bot and one use (train, rag or search), from robots.txt, IETF AIPREF, W3C TDMRep, noai directives and RSL licenses, with the reasons and a signed receipt. Use it in a crawler or RAG pipeline before fetching each new domain. Costs 0.001 USD on Base (0.002 on Solana) via x402. Invalid domain or unknown bot is never charged.

Full AI-consent report for a domain: robots.txt rules for each AI bot (training, search and user-agent crawlers), RSL license, IETF AIPREF Content-Usage, W3C TDMRep, noai meta tags, llms.txt and C2PA, combined into a 0-100 score and a training stance, plus a verifiable receipt (EAS attestation anchored on Base). Use it before crawling, training on or ingesting a site. Costs 0.005 USD in USDC via x402 (Base or Solana); without a payment it returns the x402 payment options. Unreachable sites are not charged.

What a domain's robots.txt (or llms.txt, tdmrep.json, RSL license, homepage headers) said at a given instant, with the SHA-256 of each version and its EAS attestation anchored on Base. Without `source` it returns the index of versions; with `source` (and optional `at`, RFC 3339) the document in force at that instant. Covers only domains already analysed.

Returns the signed EAS attestation of a paid query and, once anchored, its Merkle proof (OpenZeppelin format) and the on-chain attestation on Base that contains it.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id17ad19f9abe34edd.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
