Implementation Reference
- The core handler logic for the 'list_watched' tool within the call_tool_handler function. It checks if any paths are watched and returns a formatted list of monitored paths with subscriber counts, or a message if none are monitored.
elif name == "list_watched": if not watched: return [ TextContent(type="text", text="No paths are currently being monitored") ] result_lines = [f"Currently monitoring {len(watched)} paths:"] for path, sessions in watched.items(): result_lines.append(f"- {path} ({len(sessions)} subscribers)") return [TextContent(type="text", text="\n".join(result_lines))] - src/mcp_observer_server/server.py:80-88 (registration)Registration of the 'list_watched' tool in the @server.list_tools() handler, defining its name, description, and input schema (no required properties).
Tool( name="list_watched", description="List all currently monitored paths and their subscriber counts", inputSchema={ "type": "object", "properties": {}, "additionalProperties": False, }, ), - Input schema for the 'list_watched' tool, specifying an empty object with no properties and no additional properties allowed.
inputSchema={ "type": "object", "properties": {}, "additionalProperties": False, }, - Global dictionary 'watched' that stores the mapping of monitored paths to sets of subscribed ServerSession objects, directly used by the list_watched handler.
