What MistralAI-User does

Fetches a page when someone using Mistral's Le Chat asks for it. It acts for one person, in real time.

As an AI assistant, it fetches pages for a person, in real time, while they use an AI assistant. The kinds of AI agent that visit websites.

Should you allow it?

Almost always allow it. Blocking it means the assistant can't read your pages when a customer asks about you, so it answers from somewhere else. A decision guide for blocking or allowing AI crawlers.

How to allow or block MistralAI-User

MistralAI-User reads the MistralAI-User group in your robots.txt. To block it everywhere:

User-agent: MistralAI-User
Disallow: /

To allow it everywhere, even if another rule blocks other bots:

User-agent: MistralAI-User
Allow: /

Robots.txt is a request, not a lock: well-behaved crawlers follow it, impostors don't. Robots.txt for AI agents.

How it identifies itself

A typical user agent:

Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; MistralAI-User/1.0; +https://docs.mistral.ai/robots)

How to tell if it's really MistralAI-User

Mistral AI doesn't publish IP ranges or a reverse DNS domain for MistralAI-User, so a request can't be proven to come from it. Anyone can send its user agent, so treat the name alone as a claim, not proof. Ghost Agent Lab reports these requests as unverified rather than guessing.
