How to identify it

Look for the MistralAI-Training identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

How to check identity

A User-Agent match identifies a claimed client. Check the source IP and any operator-published verification method before granting access.

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-Training
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.

SourcesReviewed 2026-09-14

Identity and purpose are based on these sources. Analytics interpretation and suggested checks are Apostl guidance.
