What MistralAI-User does
MistralAI-User retrieves a URL for a live Mistral answer. It is not the MistralAI-Index crawler that discovers pages ahead of time.
How to get discovered
Allow MistralAI-User, serve extractable HTML, and keep canonical product facts on a stable URL. Mistral will not invent a citation from a blocked fetch.
Why MistralAI-User might skip you
Generic “block GPTBot and friends” snippets that also Disallow Mistral tokens, or edge rules that classify unknown AI UAs as scrapers.
robots.txt rule
Allow this token on public pages you want retrieved or cited. A CDN “Block AI bots” toggle can still 403 it after robots.txt says Allow.
# Keep MistralAI-User eligible to fetch this site
User-agent: MistralAI-User
Allow: /Mistral has not published a machine-readable range file for this token. Do not treat the user-agent alone as proof of identity.
JavaScript: reads raw HTML only.
Other Mistral bots
Training, search, and user-fetch tokens from the same operator are not interchangeable. Allow the discovery path even when you opt out of training.
