Extension Metadata

About this extension
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 it does — and doesn't

Agent Ready only sends the URL of the page you ask it to scan. It does not read page contents. It does not send anything to third-party services. It does not set tracking cookies.

Scans are subject to the agent-ready.dev free tier (3 scans / 30 days per IP).
