Does Google-Gemini-CLI respect robots.txt?

Not documented. No operator statement says whether Google-Gemini-CLI reads robots.txt, so add the rule but verify in your logs that the requests actually stop.

How do I block Google-Gemini-CLI?

Add the Google-Gemini-CLI token to robots.txt with Disallow: /. If the crawler ignores robots.txt, match the user agent at your CDN or reverse proxy and return 403 there instead.

Q: How do I verify a request really came from Google-Gemini-CLI?

You cannot, at least not from the request itself. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof. Compare the source IP against hosting and datacenter ranges instead, and rate limit anything that behaves like a crawler.

Google-Gemini-CLI is a bot operated by Google that pulls documentation and examples while an AI writes code. Gemini CLI is an AI coding agent by Google that can query and edit large codebases, generate apps from images or PDFs, and automate complex workflows directly from the te…. No IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine and a robots.txt rule alone will not stop a forgery.

robots.txt

Allow or block Google-Gemini-CLI

Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.

Block Google-Gemini-CLI

User-agent: Google-Gemini-CLI
Disallow: /

Blocks every path for this crawler only.

Allow Google-Gemini-CLI

User-agent: Google-Gemini-CLI
Allow: /

Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.

Allow, except the pages you never want quoted

User-agent: Google-Gemini-CLI
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /search

Edit the Disallow paths to match your own account, checkout and search URLs.

What blocking actually costs you

Blocking Google-Gemini-CLI mainly affects developers reading your documentation through an AI tool. Most sites want that traffic.

Verification

Is that really Google-Gemini-CLI?

A user-agent header is a string the client chooses. Scrapers copy Google-Gemini-CLI precisely because site owners allow it. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
