Atlassian MCP: Infinite auth tabs + connection timeouts

Hey, thanks for the report. This is a known issue with OAuth authentication for MCP servers, and the team is working on a fix.

Related threads:

Workaround: Toggle the MCP server off and on in Cursor settings, like you’re already doing.

For a deeper look, could you share the Output logs:

  • Open the Output panel
  • In the dropdown, select MCP: Atlassian-MCP-Server
  • Share the error messages, especially when the infinite tab loop starts

I’ll pass your report to the team and link it to the active investigation.
