AI Protocol Detector
Instantly check if any website has llms.txt, MCP, NLWeb, ai.txt, schema markup, and other AI protocols. See how AI-discoverable a site really is.
What AI Protocols Does This Tool Check?
llms.txt — The emerging standard for telling AI models about your website. Like robots.txt but for AI context. Only 8% of websites have one.
MCP (Model Context Protocol) — Enables AI assistants to directly interact with your web service through structured endpoints.
NLWeb — Natural Language Web protocol for AI-native content discovery and negotiation.
ai.txt — Structured metadata file for AI engine discovery with key facts about your site.
Schema Markup — JSON-LD structured data that helps AI understand your content type, authorship, and topic.
robots.txt AI Rules — Whether your robots.txt allows or blocks AI crawlers like GPTBot, ClaudeBot, and PerplexityBot.
AI Sitemap — Specialized sitemap with AI-specific content annotations and priorities.
Why Check for AI Protocols?
AI engines like ChatGPT, Perplexity, Google AI Overviews, and Claude use these protocols to discover and understand websites. Without them, your site may be invisible to AI — meaning you miss out on AI-generated citations, recommendations, and traffic.
Our research shows that sites with proper AI protocols are cited 59% of the time by AI tools, compared to just 41% for sites without them.
