        "ghcr.io/aknarts/chef-server-mcp:latest"
      ]
    }
  }
}

GitHub Copilot

Add to your Copilot configuration:

{
  "servers": {
    "chef-server": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "--env", "CHEF_USER=your-username",
        "--env", "CHEF_KEY_PATH=/chef/your-username.pem",
        "--env", "CHEF_SERVER_URL=https://your-chef-server.com/",
        "--env", "CHEF_ORG_ALIASES=qa=qa1,prod=production",
        "--env", "CHEF_DEFAULT_ORG=qa1",
        "--volume", "/path/to/your/.chef:/chef:ro",
        "ghcr.io/aknarts/chef-server-mcp:latest"
      ]
    }
  }
}

Important Notes:

• The --volume flag maps your local .chef directory to /chef inside the container
• The CHEF_KEY_PATH must point to the file path inside the container (e.g., /chef/your-username.pem)
• Make sure the volume path matches your actual local .chef directory location
