Hey there!

What you’re seeing isn’t intended behavior, and it isn’t caused by anything on your end. Reinstalling won’t change it, because the plugin’s manifest is the same either way. The Monday plugin (like several other third-party plugins) declares a $schema field that the current Cursor release doesn’t recognize, and instead of ignoring the unknown value the plugin loader is treating it as a load failure rather than a soft warning. We’ve let the team know and this is an issue we’re tracking.

No timeline to share yet, but I’ll post back here when there’s an update. In the meantime, using the MCP path (which you already switched to) is a solid workaround - you’re not missing anything Monday-side.
