How to verify MistralAI-User

Matching the user agent isn't enough, because any client can send it. A real MistralAI-User request comes from an IP address inside Mistral AI's published list:

• https://mistral.ai/mistralai-user-ips.json
  4 prefixes · list dated 2025-02-19 · fetched 2026-10-22

The quickest way to check a whole log is our free log checker. It runs in your browser and splits MistralAI-User requests into real and fake.

Block or allow MistralAI-User in robots.txt

User-agent: MistralAI-User
Disallow: /

Use Allow: / instead to explicitly permit it, or build a full file with the AI robots.txt generator. robots.txt is a request, not a lock: it only works for bots that honor it, and only real MistralAI-User traffic would.
