Atlassian MCP: Multiple auth tabs opened repeatedly

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After opening cursor, I get a tab for authentication of Atlassian MCP opened constantly even though I authenticated. When I authenticate manually from cursor it gets request timeout. There are a lot of same bug reported as I see

(There are more but your stupid system does not allow new users to put more than 2 links)

Toggling the MCP off and on does not work

When it will be fixed. Im sorry but this is ridiculous that such bug is being reported over and over with zero addresing from your team

Steps to Reproduce

Steps to reproduce have been already described multiple times in other topics reporting same bugs.

Operating System

Windows 10/11

Version Information

Version 3.17.8 (user setup)

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey @Krzysztof_Stepak, it’s an issue we’re tracking.

Quickest fix: if your Atlassian entry in mcp.json uses npx mcp-remote … or the /v1/sse URL, switch it to the direct form — { "url": "https://mcp.atlassian.com/v1/mcp" } — then toggle the server off and on to re-auth. The direct form uses Cursor’s built-in authentication and stops the repeated tabs.

The manual-auth timeout is usually your org’s Atlassian settings blocking the local sign-in callback - worth asking your Atlassian admin to allow http://localhost:8787/callback.

If it’s still looping after that, paste your Atlassian mcp.json entry and the MCP output log (Ctrl+Shift+U → pick MCP: <your server>) and I’ll pin it down.
