MCP server - Connect button

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Cursor plugins does not load anymore, connect button won’t appear even after cursor reload windows/restart, laptop restart. Looks like an issue with oauth, colleagues don’t have the issue so this is something conflicting on my computer.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @julien-alpaca Thanks for reporting. As a first troubleshooting step can you try disabling the plugin, re-enabling, and then going through the authentication flow and logging in? Let me know if that doesn’t solve it and we’ll go through some next steps!

Hi

Have the same issue, don’t have connect button for mcp with oauth
