# Agent-Ready Check

> Scan any website against 22 AI agent readiness standards: robots.txt, sitemaps, Content Signals, markdown for agents, MCP server cards, Agent Skills, Web Bot Auth, OAuth discovery and agentic commerce. Free, no signup, and every failing check comes with a fix prompt for your coding agent.

The scanner fetches the well-known documents, response headers and DNS records
that an AI agent would look for, reports each of the 22 checks as pass, warning,
issue or note, and maps the result onto a five-level readiness ladder.
