THEN Implement cancellation support in MCP server by listening for JSON-RPC notifications of type 'notifications/cancelled'. When received, cancel the corresponding tool execution (e.g., by cancelling asyncio tasks or setting a cancellation token) and respond with a cancellation result. Ensure that long-running tools check for cancellation periodically.

async def handle_cancellation(notification):
    request_id = notification.params.get('requestId')
    if request_id in active_tasks:
        task = active_tasks[request_id]
        task.cancel()
        # Optionally send a response indicating cancellation
