Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`backlinks`read-only	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`read-only	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`read-only	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.
`check_page`read-only	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.
