The technical details
MarkdownHow to identify it
Look for the MistralAI-User identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.
How to check identity
Compare the source IP with the current MistralAI-User IP list linked from Mistral’s crawler documentation.
Access and robots.txt
The operator documents robots.txt rules for this identifier.
Optional full-site opt-out. Merge with existing rules only if intended. robots.txt does not secure private content.
User-agent: MistralAI-User
Disallow: /Seeing 403 or 404 responses?
403 means access was denied; 404 means the resource was not found. Compare the public path, request time, edge security event and origin response to find the cause.
Separate intended restrictions and secret-file probes from pages that should work. A User-Agent name alone does not justify allowing a request.
