MistralAI-Index: what it is, its IP ranges, and how to block it
MistralAI-Index is Mistral AI's crawler for AI search and answers.
| Vendor | Mistral AI |
|---|---|
| What it is for | AI search and answers |
| In its User-Agent | MistralAI-Index |
| Its vendor's address list | https://mistral.ai/mistralai-index-ips.json |
| IP ranges | 2 |
It reads a page for an AI's search or for a person who asked an assistant, and can bring visitors. Bot Protection lets it through by default; you can block it.
How to verify it
Any bot can write MistralAI-Index in its User-Agent. A request is MistralAI-Index only when its address is in Mistral AI's published list below: check the address, not the name.
How to block it
With robots.txt, you ask it to stay out:
User-agent: MistralAI-Index Disallow: /
robots.txt is a request, not a block, and it cannot tell the real crawler from a bot wearing its name. Bot Protection verifies MistralAI-Index by its address on every request and answers it as you choose on the Set-up page, per kind or for MistralAI-Index alone; a bot that only wears the name is judged like any other bot.
