Thank you for the question! The team is almost ready to roll out "personal tools" where people will be able to connect to their own account. The focus is on Google ecosystem for now (Gmail, Calendar, etc). I don't think a Atlassian personal "tool" is on the roadmap yet.

Remi to be clear, this is a bit different topic than the personal / workspace connection (but, related).
Support for picking between workspace or personal connection for remote mcp server will be coming soon after that one.
