MistralAI-Index is a bot in the search engine crawlers category.
Crawling of the web for indexing purposes (no AI Training)
Search engine crawlers index your pages so they can appear in search results. Keep the genuine ones allowed and verify them, because fake search crawlers are one of the most common disguises for scrapers.
MistralAI-Index identifies itself with this user agent string:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; MistralAI-Index/1.0; +https://docs.mistral.ai/robots)Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
We have not confirmed whether MistralAI-Index follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

User-agent: MistralAI-Index group, MistralAI-Index ignores your User-agent: * rules, so repeat any that should still apply.MistralAI-Index from MistralAI-Index's user agent; check the operator's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
MistralAI-Index brings search traffic, so keep the real one allowed. Fake MistralAI-Index requests are a common cover for scrapers, so verify it by network rather than by name.
Transfon Security for publishersSearch crawlers fetch landing pages to check them. Keep MistralAI-Index allowed, but out of campaign and conversion data.
Transfon Security for advertisersMistralAI-Index indexes products for search results. Allow it, and block impersonators that use its name to scrape prices.
Transfon Security for e-commerceAllow MistralAI-Index on marketing and docs pages, and keep it off signed-in app pages it cannot use.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows MistralAI-Index by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

We have not confirmed whether MistralAI-Index follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.
Add "User-agent: MistralAI-Index" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "MistralAI-Index" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so MistralAI-Index may not follow it, and anyone can send MistralAI-Index's user agent, so a fake MistralAI-Index ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
