Agent Ready — Scan sites for AI agents

Make any website discoverable and parseable by AI agents. Click the toolbar icon on any page to run the full Agent Readability Score from agent-ready.dev, or jump to a single-protocol validator: • llms.txt checker — verify your /llms.txt is reachable, well-formed, and conforms to the spec • agents.json validator — confirm your agents.json describes your agents correctly • agent-card validator — check your A2A agent-card.json against the protocol • mcp.json validator — validate your MCP Server Card and discovery metadata • x402 checker — verify x402 Payment Required header support • UCP validator — confirm your Universal Content Profile is correctly published Results open in a new tab on agent-ready.dev with line-by-line check results, copy-paste fixes, and a shareable URL. The extension remembers your last 10 scans for quick access. Right-click any link on a page to scan it without leaving where you are. What we do — and what we don't Agent Ready only sends the URL of the page you ask it to scan. We do not read page contents. We do not send anything to any third-party service. We do not set tracking cookies in the extension. Scans are subject to the agent-ready.dev free tier (3 scans / 30 days per IP, no sign-in required). Sign in on the site for higher limits.
