Does kagi-fetcher respect robots.txt?

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

How do I block kagi-fetcher?

Add the kagi-fetcher 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 kagi-fetcher?

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.

kagi-fetcher is a bot that fetches single pages on demand for an AI assistant, and its operator has not been publicly identified. kagi-fetcher is an AI Assistant operated by Kagi that fetches web content to answer user queries through Kagi AI, their suite of AI-powered tools including Assistant, Res…. 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 kagi-fetcher

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 kagi-fetcher

User-agent: kagi-fetcher
Disallow: /

Blocks every path for this crawler only.

Allow kagi-fetcher

User-agent: kagi-fetcher
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: kagi-fetcher
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 kagi-fetcher means a person who asks about one of your URLs gets an error instead of a summary. That is a support and reputation trade-off, not a training one.

Block every crawler in the directory at once

Verification

Is that really kagi-fetcher?

A user-agent header is a string the client chooses. Scrapers copy kagi-fetcher 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.
