Authenticated Remote MCP

Hi all,

First off—thanks for this great starter! I'm using it for a proof of concept and running into an issue while trying to integrate the official Atlassian MCP using their SSE endpoint:
https://mcp.atlassian.com/v1/sse

I followed the example that includes a comment about adding MCPs, but I'm seeing the following error when calling mcp.connect:
`No authProvider provided in the transport options. This client will only support unauthenticated remote MCP Servers`

And on the server side:
`SseError: SSE error: Non-200 status code (401)`
It seems like authentication is required, but I’m unsure how to properly provide the authProvider in this context.

Am I missing a configuration step or is additional setup required to connect to Atlassian's MCP?
Any guidance or examples would be greatly appreciated!

Thanks in advance!

edit -
I'm sure I am missing the DurableObjectOAuthClientProvider configuration, but I wonder how it is working out of the box, without any configuration here - https://playground.ai.cloudflare.com/

Start by comparing the MCP connection example with the setup used by https://playground.ai.cloudflare.com/. Investigate how mcp.connect receives an authProvider and how DurableObjectOAuthClientProvider is configured, then reproduce the Atlassian SSE connection and verify that authentication prevents the server-side 401 response.
