Official docs
MistralAI-User is Mistral's user-triggered fetcher: when someone asks Le Chat about a URL or a question needing live web content, this agent retrieves the page for citation. Like other user-fetch agents, traffic from it represents real people reaching your content through an AI conversation.
Does MistralAI-User respect robots.txt?
Mistral documents the agent and states it respects robots.txt directives.

Should you block MistralAI-User?
For most sites, no. MistralAI-User powers visibility: blocking it removes your pages from the cited answers Mistral's assistant shows its users — the AI-era equivalent of de-indexing yourself from a search engine. Block it only if you deliberately don't want that audience. Our guide on blocking AI bots covers the trade-offs in detail.
