Features & Capabilities

See what AI agents can actually discover, read, and use on the current site.

Agent Readiness Inspector runs 22 standards-based checks directly in Firefox:

robots.txt, sitemap, and AI crawler rules
llms.txt and markdown negotiation
Content Signals and Web Bot Auth
Link headers, Agent Skills, and API Catalogs
MCP Server Cards, OAuth discovery, and WebMCP
emerging agent-commerce protocols

Every scan includes a comparable score and readiness level, raw evidence for each verdict, and prioritized fix prompts you can copy into a coding agent.

Use the toolbar popup for a quick scan or open the same report in the Firefox sidebar. Save sites to build local score history, scan several sites from the dashboard, and put selected sites on watch. Monitoring records regressions in a local inbox; browser notifications are optional.

Because the audit runs inside Firefox, it can inspect staging sites and many authenticated pages that an external scanner cannot reach. Firefox privacy and cookie protections may limit session access on some sites.

You can connect your own Cloudflare URL Scanner token and explicitly run an outside scan for comparison. Firefox asks for optional authentication and browsing-activity data permissions before this transfer. Declining leaves all local auditing available, and you can disconnect Cloudflare at any time.

Website URLs and response content are handled only to produce the audit. Results, saved sites, history, settings, and alerts remain in local Firefox extension storage. 301.st receives no scan or browsing data. There is no analytics, telemetry, advertising, or remotely hosted code.

The extension needs access to websites because its single purpose is to audit any HTTP or HTTPS site you choose. It does not inject content into visited pages.

Agent Readiness Inspector is an independent implementation of open web standards. It is not affiliated with or endorsed by Cloudflare.

Is Agent Readiness Inspector 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 Readiness Inspector requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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 Readiness Inspector is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
