Multi-user authentication not working with self-hosted Jira/Confluence

[ml-nic]

I'm trying to use the new multi-user authentication feature from PR #416 with a self-hosted Jira/Confluence setup, but I can't get it to work with either sse or streamable-http transports.

Environment
Self-hosted Jira/Confluence (Server/Data Center)
Tried both sse and streamable-http transports
Using PAT authentication

Is multi-user authentication supported for self-hosted instances?
Are there different configuration requirements for Server/Data Center vs Cloud?
What's the correct setup for self-hosted environments? Do I need to add headers, does the LLM need to add something when using the mcp tools?

I managed to make it work for self hosted confluence.

there were a couple issues why it initially did not work for me:

• using sse transport does not work for this, it has to be streamable-http
• the endpoint you configure in your mcp client must be /mcp/ (with the trailing / ) otherwise there is some temporary redirect (307) which drops the authorization header

with those 2 issues out of the way, authorization header provided PAT works for me without issues.
