Does Cursor respect robots.txt?

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

How do I block Cursor?

Add the Cursor 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 Cursor?

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.

Cursor is a bot that pulls documentation and examples while an AI writes code. Cursor is an AI coding agent that helps write, edit, and understand code. 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 Cursor

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 Cursor

User-agent: Cursor
Disallow: /

Blocks every path for this crawler only.

Allow Cursor

User-agent: Cursor
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: Cursor
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 Cursor mainly affects developers reading your documentation through an AI tool. Most sites want that traffic.

Verification

Is that really Cursor?

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

Datacenter IP detectionNearly every real AI crawler egresses from cloud ranges. A residential IP claiming to be one is the first thing to check.IP reputation checkSee whether the address behind a fake crawler hit has a history of abuse elsewhere.Residential proxy detectionScrapers that get blocked by user agent often come back through residential proxy pools.
