Streamable HTTP transport for remote agents

[parubets]

Any chance we can have support for Streamable HTTP transport?
I would like to just enter the URL endpoint for my agent API backend and the api-key.
Would be super powerful addition to stdio transport.

@parubets thanks for the input! We prioritized stdio at the moment because most clients are embedding terminal agents as a subprocess, but we would love to add HTTP support in the future. We worked hard to make sure we weren't doing anything in the protocol that would inhibit this move in the future. We just prioritized stdio for the initial release.

We do a bunch of work for the US federal government with sensitive data. We run our Claude Code and Gemini CLI agents in a devcontainer locally to help prevent unauthorized access to and leaking of this sensitive data by the agent because they do not run locally on our laptops.

@benbrandt Curious if the current stdio protocol supports that use case or if we will need to wait for an HTTP based protocol.

I've been running Claude Code in a terminal window in Zed so I'm guessing the answer is we will need HTTP based protocol?

You can now use ACP with remote sessions, so that the process is running in the remote host, but I am not sure if this will work with your dev container setup.

Thanks @benbrandt. I'll give it a try and see where the gaps are. Thanks!
