Frequently Asked Questions
What Traffic Patterns Should I Expect From MistralAI-Index?
MistralAI-Index revisits your site on a flexible schedule, often requesting several pages in a burst. Activity usually increases when your content changes or its index refreshes, with quiet intervals between crawl passes.
Does MistralAI-Index Follow Robots.txt Rules?
MistralAI-Index is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether MistralAI-Index respects it.
Is MistralAI-Index Used for AI Model Training?
Not ordinarily. MistralAI-Index is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking MistralAI-Index Affect AI Search or Citations?
Yes. Blocking MistralAI-Index can keep your pages out of the AI search index it supplies, reducing their eligibility to appear or be cited in that product's answers.
Does MistralAI-Index Access Private Content?
No special access. MistralAI-Index can reach only content available to anonymous visitors. Make sure staging sites and other sensitive areas require authentication.
How Can I Verify a Request From MistralAI-Index?
Agent Analytics tracks visits from MistralAI-Index and every other known AI agent, crawler, and scraper, then authenticates each visit using MistralAI-Index's published verification method. You can also check your server logs for requests whose user-agent string contains "MistralAI-Index". Look for bursts that follow links across several pages and recur over time. A matching log entry alone is not proof because any bot can claim to be MistralAI-Index.
How Is MistralAI-Index Different From Other Mistral Agents?
Mistral operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
