Install Codex Control Plane MCP in Goose

What you need first

• Goose, installed.
• uv, which gives the uvx command the server starts with.

Steps

1. Open ~/.config/goose/config.yaml. On Windows it is %APPDATA%\Block\goose\config\config.yaml.
2. Add this entry. If the file already has extensions, add only the entry inside it.

extensions:
  "codex-control-plane-mcp":
    type: stdio
    name: "codex-control-plane-mcp"
    enabled: true
    cmd: "uvx"
    args: ["codex-control-plane-mcp==0.2.1"]
    env_keys: []
    envs: {}
    timeout: 300

3. Save the file and start a new Goose session.

Check it worked

Ask Goose: List the tools of codex-control-plane-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Goose sees. Install it, or write the full path of uvx in the config.

Nothing changes after a restart

The file is not valid YAML any more. Check that the entry is indented like the lines around it.
