Features & Capabilities

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).

Is Agent Ready — AI Agent Scanner Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Agent Ready — AI Agent Scanner requires very minimum permissions.

Risk impact analysis details
  • Low Request access to the following domains: agent-ready.dev
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Agent Ready — AI Agent Scanner is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
