MCP - SSE/Streamable HTTP - Add support for request headers

[NicoBonaminio]

Please explain the motivation behind the feature request.
Whilst using the SSE transport mechanism for MCP Extensions, there does not appear to be any way to authenticate with the remote server by passing in a --header.

Describe the solution you'd like
Currently SSE shows environment variables, which don't work with SSE, and should ideally have a "headers" area so the user can pass request header key value pairs. For example:
key: Authorization, value: Bearer 123

Describe alternatives you've considered
There aren't any alternatives currently for remote MCP servers within Goose to authenticate.

It seems this was added in the latest release (Both desktop + CLI - add new Streamable HTTP extension). Maybe this can be closed now?

Hi,
I'm using Version 1.1.4 (1.1.4) and still cannot add http request headers for sse.

@michaelneale I can ship a 6 pack if it can help to fix it :)

[michaelneale]

there is a new version out which can use mcp oauth - not sure if that can address this, is this still needed now @olamy ?

@michaelneale thanks but don't worry about this. maybe this issue can closed
3 weeks later and sse is already not used anymore :)
But thanks for the info I really like the idea about mcp oauth!

[michaelneale]

This is still a problem. Can't pass a bearer token as a header.
