ACPs Hosted as Docker Containers

[LeoBorai]

Body

What are you proposing?

It would be nice to be able to connect Zed to an ACP running on a Docker container.

Why does this matter?

Allows users to introduce different agents setups hosted on Docker.

Are there any examples or context?

I have the following Docker image:
https://github.com/LeoBorai/dkc

Which I use for AI Assisted Coding, where I have my setup of Claude Code and its tools.
In this setup I have pre-installed software and Claude plugins I use in different working
environments.

Instead of having to install and configure the AI agent, I can just spin this container
anywhere I would like to run it.

Possible approach

What Im currently doing is running the container via agent_servers in the settings.json:

  "agent_servers": {
    "DKC": {
      "type": "custom",
      "command": "docker",
      "args": ["exec", "-i", "dkc-claude-acp", "claude-agent-acp"]
    },
  },

But seems like it attempts to find binaries locally instead of in the container.
I see Zed attempts to find binaries like GH Copilot CLI or Claude locally by default.

Perhaps we can make it rely only on the JSON RPC API exposed by the claude-agent-acp?
