robots.txt token
MistralAI-User

MistralAI-User identifies itself with the token MistralAI-User. That is the case-insensitive substring to grep for in access logs, and the exact name to put after User-agent: in robots.txt. It fetches a page live, at the moment a user asks something.

Allow or block MistralAI-User in robots.txt

Robots.txt applies the most specific matching group, so a group naming MistralAI-User overrides your User-agent: * rules for this bot alone.

Allow
User-agent: MistralAI-User

Disallow: /

What blocking costs you: Mistral's Le Chat can't fetch your pages on demand.

FAQ

What is the MistralAI-User user agent?
MistralAI-User announces itself with the User-Agent token "MistralAI-User". That token is the case-insensitive substring to match in server logs and the exact name to put after "User-agent:" in robots.txt. Mistral does not publish one fixed full string, so match on the token rather than the whole line.
Who operates MistralAI-User and what does it collect?
MistralAI-User is run by Mistral and fetches a page live, at the moment a user asks something. In the AI picture that puts it under "Answering you": A live user prompt made an AI fetch your page to answer.
How do I block MistralAI-User?
Add a robots.txt group naming the token exactly: User-agent: MistralAI-User followed by Disallow: /. Robots.txt matches the most specific group, so a MistralAI-User group overrides whatever your User-agent: * group says. Mistral's Le Chat can't fetch your pages on demand.
Should I block MistralAI-User?
That depends on what you lose. Mistral's Le Chat can't fetch your pages on demand. Sites chasing AI citations usually keep the live-answer and AI-search bots open and make a separate decision about the training crawlers. Run your domain through the AI crawler access checker to see which ones your robots.txt lets in today.
Can MistralAI-User be spoofed?
Yes. A User-Agent header is self-reported, so any scraper can claim to be MistralAI-User. The token is fine for reporting and for robots.txt, but if you are rate-limiting or firewalling on it, verify the request IP against Mistral's published ranges before you trust the name.

Paste a full User-Agent line and identify any crawler with the AI bot user agent list and lookup, or see every token side by side.
