Agent Readiness Inspector runs 22 standards-based checks directly in Firefox: 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. ## Rankings - #121,184 — Overall - #115 — agent ## Permissions and access ### Permissions - `storage` - `alarms` - `` ## Safety - **Risk impact:** Moderate risk impact - **Risk likelihood:** High risk likelihood ### Analysis details - Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site. - This extension was recently updated in the past month.
