Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, which version of Cursor are you using? I just checked this on version 1.2.4 and everything works fine. Also, let me know which MCP server you are using.

Could you share the MCP server settings?

    }
  }

This method doesn’t work in Cursor. You can try installing it using this instead. For that, you’ll need Docker.

Thanks for clarify. I am actually developing an MCP server with OAuth authorization. I tried with the sample inside here python-sdk/examples/servers/simple-auth/mcp_simple_auth at main · modelcontextprotocol/python-sdk which needs to run the Authorization Server and MCP server separately on local env.

Then I added this MCP into the config file like following

{“mcpServers”: {“simple-auth-server-time”: {“type”: “streamable-http”,“url”: “http://127.0.0.1:8001/mcp”,“auth”: {“type”: “oauth”,“authorization_server”: “http://127.0.0.1:9000”,“client_id”: “auto-register”,“scopes”: [“user”]}}}}

This mcp can be authorized in Cursor 1.1.7 which means it can login and logout successfully. However, when I upgrade to 1.2.4, it directly shows mcp has already been logged in and when I clicked logout, nothing happened.
