Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I typically have 4-8 different projects open in different cursor windows during my work day. I have the Atlassian MCP configured for cursor agent access to JIRA and Confluence:

    "Atlassian": {
      "command": "npx -y mcp-remote https://mcp.atlassian.com/v1/sse",
      "env": {},
      "args": []
    },

This MCP pops up a tab in the browser to handle auth. But instead of a single auth tab, I’m seeing many. I originally thought I was seeing one per cursor window, but when I just restarted cursor with 6 projects/windows, I had 10 browser tabs opened.

Since the MCP is specified at the user/app level (in my .cursor/mcp.json file), it would be awesome if the auth could be handled at a higher level to only open a single browser tab.

Steps to Reproduce

  1. Configure the Atlassian MCP as above
  2. Open multiple cursor projects in different windows
  3. Restart cursor, there will be multiple browser windows opened

Expected Behavior

Atlassian MCP auth happens only once

Operating System

Does this stop you from using Cursor

No - Cursor works, but with this issue

I would add that opening one more tab invalidates all the previous tabs. If N browser tabs are opened, and I click “Approve” in a tab number < N, I get the error message Invalid session. Only the last tab opened works as expected.
