Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_ai_bot_access | Reads the public robots.txt of a website (one request to https://<host>/robots.txt, nothing else on the site) and says, for each AI crawler and AI agent of the migurei bot registry (training crawlers such as GPTBot and ClaudeBot, search bots, fetchers that act for a user, and others), whether that bot is allowed or disallowed for the path "/", which robots.txt rule decided it, and whether the file exists. Each bot also carries observed_on_pw: the counts our own lab site pw.migurei.ai recorded for that bot (published on https://pw.migurei.ai/ja/research/ai-bot-first-visits; the same for every domain, not about the domain asked, not a prediction). Input is a domain or URL; only public domain names are accepted (no IP addresses, no ports, no private hosts). Read-only; the domain is not stored. robots.txt is a request to bots, not access control, and a User-Agent is only a claim. | Read-only |
| get_site_info | Returns the facts published on this website, in Japanese: service overview, plans, prices and payment terms, how the scanner behaves, how to contact us, and the operating company. Each fact comes with the URL of the page that shows it. Read-only; it returns nothing that is not on the pages. | Read-only |
