ChatGPT Business - MCP Server cannot connect EVER

[Travis Polland]

I continue to struggle with the MCP server actually working inside of ChatGPT. I have a business account for my entire team, and I enable the Atlassian MCP for everyone (built-in). It does not ask for me or anyone on my team to authenticate. The ChatGPT agents cannot use the tool at all. I have disabled / re-enabled it. 

Claude and Cursor IDE work just fine (except that Cursor pops open 4-9 windows to reauthenticate like twice a day - another issue to report)

On top of what Peter said, I just wanted to jump in here and add a note that there's a dedicated MCP server forum group that might be helpful in cases like this: Atlassian Rovo MCP Server 🙂

Hi @Travis Polland , 

I'm sorry to hear that. MCP relies on proper OAuth consent and workspace configuration in ChatGPT—Business plans manage connectors centrally, so no per-user auth prompt is expected if enabled. The "cannot use tool" error usually means incomplete consent (e.g., no site admin has authorized the app yet) or mismatched scopes during setup.

1st option - You can first try force OAuth Consent:

• MCP requires a one-time 3LO (three-legged OAuth) consent from a Confluence site admin. Since Business skips per-user prompts, you should manually trigger it:
  • Log in as site admin (your account) to admin.atlassian.com > Products > Confluence > Ensure MCP Server is active (Security > MCP Server > Toggle on if needed).
  • In a browser, hit the authorize URL (adapt your app's Client ID if custom, or use Atlassian's built-in for the connector):
    • https://auth.atlassian.com/authorize?audience=api.atlassian.com&client_id=YOUR_CLIENT_ID&scope=offline_access%20read:confluence-content.all%20read:jira-work&response_type=code&redirect_uri=https://chatgpt.com/connector_platform_oauth_redirect

  • Complete the consent (grant read access) -> this registers the app for your site.

• Back in ChatGPT: Retry the agent. It should now connect without error.

2nd option - Check few tips for ChatGPT:

• Clear cache/cookies for chatgpt.com and atlassian.net -> Then try incognito mode (this works most of the time :))
• In ChatGPT: Settings > Developer > View errors > Check for specifics (like the scope issue: "unauthorized_client").
• Business plan: Ensure your team is in the allowed group for the connector (Settings > Workspace > Manage users > Connectors access). 

It's usually the consent step that's missed in Business setups. If "internal server error" or similar persists, contact Atlassian Support (support.atlassian.com/contact > Rovo/MCP > Integration issues) with your site URL.

Hope everything works out well for you and happy new year!!!
