User-triggered fetchers · Mistral

MistralAI-User

Fetches a page when a user of Le Chat asks about it. Mistral says it is not used for training.

Operator: Mistral
Purpose: Live user request. Fetchers that load a page because a person asked an assistant about it. Blocking one means the assistant can’t open your pages on request.
robots.txt token: MistralAI-User
User agent: Mozilla/5.0 (compatible; MistralAI-User/1.0; +https://docs.mistral.ai/robots)
Documentation: docs.mistral.ai/robots/

Block MistralAI-User

Add a group naming it to /robots.txt. Compliant crawlers stop before requesting any page. A firewall rule on the user agent is the only way to enforce it against crawlers that ignore robots.txt.

User-agent: MistralAI-User
Disallow: /

Allow MistralAI-User when everything else is blocked

A group naming the bot wins over User-agent: *, so an explicit allow lets it in while your catch-all rules stay in place.

User-agent: MistralAI-User
