Hey, thanks for the report. This is a known issue in versions 2.3.18+ - it’s a regression with the browser tools agent detection.

I can see the screenshot with the error “No MCP resources available” - that’s exactly what other users are experiencing too.

The good news is this should be fixed in version 2.4, which you can get by switching to early access. Just open Cursor Settings > Beta > Early Access
