xAI-Grok

Another community-listed name for xAI's crawling. xAI documents nothing about it.

Where this comes from

  • Community-listed; no vendor documentation. No vendor page names this token.
  • Robots.txt behaviour undocumented.
  • Counted in the readiness score. It can keep a site out of AI search or answers, so a block costs points.

What blocking it costs

xAI / Grok says this token controls more than training, so a block can keep your pages out of its answers or product features. The score counts it, so a block costs points.

The robots.txt lines

To let it in (a group that names the crawler replaces any wildcard rules for it, so this also lifts a User-agent: * block):

User-agent: xAI-Grok
Allow: /

To keep it out:

User-agent: xAI-Grok
Disallow: /

A rule in robots.txt is a request. Whether this crawler honours it is undocumented. The robots.txt generator writes a whole file with the same split: block the training crawlers, keep the search and answer crawlers.
