Implementation Reference
- main_b.py:577-580 (handler)The main handler function that implements the pull_image tool logic by executing 'podman pull' on the provided image and returning the result.
async def pull_image(self, args: Dict[str, Any]) -> Dict[str, Any]: image = args.get("image") result = run_podman(["pull", image]) return {"output": f"Pulled image: {image}" if result["success"] else f"Error: {result['stderr']}"} - main_b.py:356-369 (schema)The input schema definition for the pull_image tool, specifying the required 'image' parameter.
Tool( name="pull_image", description="Pull a container image from a registry", inputSchema={ "type": "object", "properties": { "image": { "type": "string", "description": "Image name with optional tag" } }, "required": ["image"] } ), - main_b.py:459-472 (registration)The dictionary mapping tool names to their handler methods, registering 'pull_image' to self.pull_image.
