What is Claude-User?
Published . Updated .
Claude-User: Anthropic's user agent for fetching a web page when a person's question to Claude needs that page.
Claude-User is the bot behind a live page read: when Claude decides it needs a page to answer you, the request comes from Claude-User. It follows robots.txt, and Anthropic says blocking it may make a site less visible in Claude's answers.
In Only Fan Out, pages Claude opens directly show up as searches tagged fetch. How Claude searches the web explains when Claude opens a page in full.
