I've installed your MCP tool following the steps on your site, and it's mostly working great. I can get logs and other data without any issues.
The problem is with screenshot capture specifically when using it with Cursor MCP. It works fine in Chrome, but when I try to take screenshots in Cursor, it just doesn't work.
Any tips on how to fix this?
Thanks!
