MistralAI-Index: what it is, who runs it, and how to allow or block it

MistralAI-Index is a crawler run by Mistral. It reads pages ahead of time, to train a model or to build an index. Its name in robots.txt, how it shows up in server logs, whether its identity can be checked, and how to allow or refuse it on each platform.

What MistralAI-Index is

MistralAI-Index is a crawler run by Mistral. It reads pages ahead of time, to train a model or to build an index.

Should you refuse it?

MistralAI-Index reads ahead of time. Refusing it keeps your pages out of what Mistral collects them for. It does not change how Google or Bing rank you: search crawlers go by other names, with rules of their own.

robots.txt is a request. A crawler that honours it stays out; nothing in the file stops one that does not. What is enforced is what the server or the edge in front of it refuses.

Is a request really MistralAI-Index?

Citable holds no published address list for Mistral, so a read that claims to be MistralAI-Index is recorded as unknown rather than verified. A user agent is a claim, and anyone can send it.

Allowing or refusing MistralAI-Index in robots.txt

Add a group under its name, “User-agent: MistralAI-Index”. “Allow: /” lets it read the site and “Disallow: /” refuses it.

A group that names a crawler replaces the * group for that crawler; it does not add to it. Paths the * group closes are open to a crawler with its own group unless they are repeated there.

Refuse MistralAI-Index:

User-agent: MistralAI-Index
Disallow: /

About Citable

Citable strips the UI from a website for AI agents and serves them only the content.

When an AI agent — ChatGPT, Claude, Perplexity or any of the 81 that Citable recognises — opens a page, Citable removes the theme, scripts, navigation and layout and serves only the content: the same facts, at the same URL, on the site's own domain. People and Google still get the full designed page.
