How to block or allow it
robots.txt rules are read per crawler: CCBot follows a group that names it, or else the User-agent: * group. To block it everywhere:
User-agent: CCBot
Disallow: /The AI crawler robots.txt generator makes these lines for any mix of crawlers. The check reads only your homepage path, robots.txt, llms.txt and a HEAD of llms-full.txt; see exactly what is fetched.
