AI Discoverability Checker
Updated Sep 4, 2026Enter any URL — real, live checks run against it: robots.txt, sitemap, AI crawler rules, Content Signals, llms.txt/markdown, structured data, and agent-discovery docs (A2A Agent Card, MCP Server Card). Not a simulated score — actual fetches against the real site, right now.
Leave unchecked if not sure — a few checks only count as a real gap when the underlying feature exists.
This tool checks what's inviting agents and crawlers in. For the other side of a site's edge setup — what's blocking traffic before it ever reaches the app — see the WAF Checker .
Frequently asked questions
What does this actually check?
Real, live checks against the URL you enter: robots.txt and whether it addresses AI crawlers by name, sitemap.xml, Content Signals, llms.txt / markdown availability, JSON-LD structured data, and the two agent-discovery documents (A2A Agent Card, MCP Server Card). Modeled on the categories Cloudflare's own AI Crawl Control diagnostics use.
Why would my site fail checks I've never heard of?
Most of these conventions (llms.txt, A2A Agent Cards, MCP Server Cards) are new — normal to be missing them entirely. Failing isn't a penalty score, just a real gap between what exists today and what AI agents/crawlers can currently discover about the site.
Do you store the URLs people check?
No — each check is a live, stateless request. Nothing about what you check is logged or retained.
