Install Fitter in Agenvoy

What you need first

• Agenvoy, installed.
• Docker, which gives the docker command the server starts with.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "servers": {
    "fitter": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "ghcr.io/pxyup/fitter-mcp:v1.8.3"]
    }
  }
}

3. Save the file and restart Agenvoy.

Check it worked

Ask Agenvoy: List the tools of fitter.

If it does not start

Cannot connect to the Docker daemon

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

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
