What is the MistralAI-User user agent?

Requests from MistralAI-User carry "mistralai-user" in the User-Agent header (matching is case-insensitive). The full string includes a version number that changes over time; Mistral's documentation lists the current one. In robots.txt, the token is MistralAI-User.

How do I verify MistralAI-User?

Mistral publishes the IP ranges MistralAI-User uses. A request is real when its IP is inside that list. Paste an IP into HadoSEO's free bot verifier to check it against the published data.

How do I block MistralAI-User in robots.txt?

Add "User-agent: MistralAI-User" followed by "Disallow: /" to your robots.txt. robots.txt is a request, not a lock: a scraper using MistralAI-User's name ignores it, which is why verification matters.

Can I see when MistralAI-User visits my site?

Yes. HadoSEO logs every MistralAI-User request by page, checks it against Mistral's published data, and flags requests that use the name from IPs Mistral doesn't own. For a one-off look, the free log file analyzer reads a week of your server logs in the browser.

How to verify a real MistralAI-User request.

Mistral publishes the IP ranges MistralAI-User uses. A request is real when its IP is inside that list.

01Check the User-Agent header contains "mistralai-user" (case-insensitive). That is only a claim: anyone can send it.
02Download Mistral's published list (https://mistral.ai/mistralai-user-ips.json) and check the request IP falls inside one of its ranges.
03Inside the list: the real MistralAI-User. Outside it: a request using MistralAI-User's name from someone else's server.

Skip the lookups: the free bot verifier checks one IP against the same registry, and the log file analyzer checks every MistralAI-User request in a week of access logs. Requests that fail are flagged as spoofed, not hidden.

[ robots.txt ]

Block or allow MistralAI-User in robots.txt.

Add one of these groups to the robots.txt at your domain root. The token matches case-insensitively.

block MistralAI-User

User-agent: MistralAI-User
Disallow: /

allow MistralAI-User

User-agent: MistralAI-User
Allow: /

robots.txt only binds crawlers that choose to follow it. A scraper sending MistralAI-User's user agent from its own servers won't, which is why HadoSEO checks the IP behind every request.
