Install PineForge — offline PineScript v6 backtest MCP in Goose

What you need first

• Goose, installed.
• Docker, which gives the docker 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:
  "pineforge-codegen-mcp":
    type: stdio
    name: "pineforge-codegen-mcp"
    enabled: true
    cmd: "docker"
    args: ["run", "-i", "--rm", "ghcr.io/pineforge-4pass/pineforge-codegen-mcp:v0.9.18"]
    env_keys: []
    envs: {}
    timeout: 300

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

Check it worked

Ask Goose: List the tools of pineforge-codegen-mcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Goose.

Nothing changes after a restart

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