What Claude-SearchBot does

Crawls the web to improve the search results Claude gives its users.

As an AI and search crawler, it indexes pages so a search engine or AI search tool can find, cite and link to them. The kinds of AI agent that visit websites.

Should you allow it?

Allow it, unless you deliberately want to stay out of that search engine. Blocking it removes you from its results and answers. A decision guide for blocking or allowing AI crawlers.

How to allow or block Claude-SearchBot

Claude-SearchBot reads the Claude-SearchBot group in your robots.txt. To block it everywhere:

User-agent: Claude-SearchBot
Disallow: /

To allow it everywhere, even if another rule blocks other bots:

User-agent: Claude-SearchBot
Allow: /

Robots.txt is a request, not a lock: well-behaved crawlers follow it, impostors don't. Robots.txt for AI agents.

How it identifies itself

A typical user agent:

Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Claude-SearchBot/1.0; +Claude-SearchBot@anthropic.com)

How to tell if it's really Claude-SearchBot

Anthropic doesn't publish IP ranges or a reverse DNS domain for Claude-SearchBot, so a request can't be proven to come from it. Anyone can send its user agent, so treat the name alone as a claim, not proof. Ghost Agent Lab reports these requests as unverified rather than guessing.
