Atlassian MCP server giving 403 error from Claude just for some users

[Alejandro Álvarez]

Hi there,

We are a facing a strange bug. We use the atlassian mcp from Claude. Some users are able to browse JIRA and Confluence data without any problem, others can only browse JIRA but not Confluence. We have re-connected everything several times, but nothing worked.

Could you help?

Hey Alejandro,

For the users that can only browse Jira, do they have a Confluence license? 

I would recommend verifying this first as a 403 for Confluence but not Jira usually points to a permissions issue rather than an MCP configuration issue.

Hey Jason, thanks for answering.

Yes, they have confluence license. They use confluence on a daily basis. The can also use Rovo in confluence. I've checked another user similar to the affected ones, they belong to the same groups and have access to the same apps in atlassian.
