Cursor IDE
Describe the Bug
I’m trying to create a .cursor/mcp.json file for my repository, the configuration contains an remote mcp server which requires oauth.
The IDE identifies the mcp, and notices that it requires login. When using the login option from settings, the redirect uri generated by cursor returns 404, and the login process fails.
Steps to Reproduce
Create a new project.
Create a .cursor/mcp.json file.
Configure an http mcp server which requires oauth inside that file.
Go to settings and click Needs Login
Authorize
Experience 404
Expected Behavior
I expect the uri link generated to be valid.
