Registry code: 16ba85d9016f9597
Fourward's free tools check how ready a website is for AI search. Use check_ai_visibility for an overall score out of 100 across crawler access, homepage, structured data, entity and content signals. Use check_ai_crawlers to see which of 20 AI crawlers (ChatGPT, Claude, Perplexity, Gemini and others) a site's robots.txt and firewall let in. Pass a bare domain such as example.com. Results list problems and scores, not fixes. Both tools only read public pages and change nothing.

- What tools does fourward have?
- 2 tools: check_ai_crawlers, check_ai_visibility.
- Is fourward 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.
check_ai_crawlers unknown 2h ago
Shows which of 20 AI crawlers can read a website's homepage: AI search and answer bots (OAI-SearchBot, ChatGPT-User, Claude-SearchBot, PerplexityBot, Googlebot, Bingbot and more) and AI training bots (GPTBot, ClaudeBot, Google-Extended, CCBot and more). Applies the site's robots.txt rules per bot the way RFC 9309 and Google do, tests the firewall by fetching the homepage as a browser and as four AI bots, and reports llms.txt and sitemap lines. Takes about 10 seconds.

Scores how well AI search engines (ChatGPT, Perplexity, Gemini, Google AI Overviews) can find, read and understand a website. Runs 30 checks in five groups: AI crawler access, what the homepage tells machines, structured data, entity and authority (Wikidata, Wikipedia, linked profiles) and AI-ready content (llms.txt, pricing, proof, docs, comparison pages). Returns a score out of 100, a grade, a score per group and every problem found, with the points it costs. Takes 10 to 30 seconds.

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 id16ba85d9016f9597.

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.
