Cannot Use Docker Daemon on Darwin

[rrpolanco]

Describe the bug

When trying to run a local, dockerized mcp server I get the error: - *mcp.Toolset start failed: failed to initialize MCP client: Docker Desktop is not Running.

toolsets:
  - type: mcp
    command: docker
    args:
      [
        "run",
        "-i",
        "--rm",
        "-e",
        "JIRA_URL",
        "-e",
        "JIRA_USERNAME",
        "-e",
        "JIRA_API_TOKEN",
        "ghcr.io/sooperset/mcp-atlassian:latest",
      ]
    env:
      JIRA_URL: "<JIRA_COMPANY_URL"
      JIRA_USERNAME: "Rafael Polanco"
      JIRA_API_TOKEN: "<API-TOKEN>"

Why is Docker Desktop required when using type: mcp + command: docker?

cagent/pkg/tools/mcp/stdio.go

Line 37 in 099802c

if c.command == "docker" && runtime.GOOS != "linux" && !desktop.IsDockerDesktopRunning(ctx) {

Similar to Linux, I'd like use the docker daemon on MacOS and not be required to use DD.

Version affected

Expectation

I'd like to use the docker daemon only on MacOS.

Hi @rrpolanco, how do you have Docker running on your Mac if you're not using Docker Desktop?

@dgageot I'm using OrbStack and Colima.
