Implementation Reference
- complete_fastmcp_server.py:353-375 (handler)Primary handler for 'stop_ecs_instances' tool. Registered via @app.tool(). Dynamically locates and calls the OOS_StopInstances function from oos_tools by matching keywords in function name.@app.tool() def stop_ecs_instances(region: str = "cn-beijing", instance_ids: List[str] = None) -> str: """停止ECS实例 Args: region: 区域ID，如cn-beijing instance_ids: ECS实例ID列表 """ try: sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'alibaba_cloud_ops_mcp_server')) from tools import oos_tools if not instance_ids: return "请提供ECS实例ID列表" for tool_func in oos_tools.tools: if hasattr(tool_func, '__name__') and 'stop' in tool_func.__name__.lower() and 'instance' in tool_func.__name__.lower(): result = tool_func(RegionId=region, InstanceIds=instance_ids) return str(result) return f"ECS实例停止功能可用，region: {region}, 实例: {instance_ids}" except Exception as e: return f"ECS实例停止失败: {str(e)}"
- Core helper function OOS_StopInstances invoked by the main handler. Uses Alibaba Cloud OOS to bulk stop ECS instances via execution template 'ACS-ECS-BulkyStopInstances'. Includes Pydantic Field definitions for input schema.@tools.append def OOS_StopInstances( InstanceIds: List[str] = Field(description='AlibabaCloud ECS instance ID List'), RegionId: str = Field(description='AlibabaCloud region ID', default='cn-hangzhou'), ForeceStop: bool = Field(description='Is forced shutdown required', default=False) ): """批量停止ECS实例，适用于需要同时管理和停止多台ECS实例的场景。""" parameters = { 'regionId': RegionId, 'resourceType': 'ALIYUN::ECS::Instance', 'targets': { 'ResourceIds': InstanceIds, 'RegionId': RegionId, 'Type': 'ResourceIds' }, 'forceStop': ForeceStop } return _start_execution_sync(region_id=RegionId, template_name='ACS-ECS-BulkyStopInstances', parameters=parameters)
- Pydantic Field definitions providing input schema and descriptions for the OOS_StopInstances function parameters.InstanceIds: List[str] = Field(description='AlibabaCloud ECS instance ID List'), RegionId: str = Field(description='AlibabaCloud region ID', default='cn-hangzhou'), ForeceStop: bool = Field(description='Is forced shutdown required', default=False)
- Shared helper function that starts an OOS execution template and polls for completion synchronously. Used by all OOS tools including stop instances.def _start_execution_sync(region_id: str, template_name: str, parameters: dict): client = create_client(region_id=region_id) start_execution_request = oos_20190601_models.StartExecutionRequest( region_id=region_id, template_name=template_name, parameters=json.dumps(parameters) ) start_execution_resp = client.start_execution(start_execution_request) execution_id = start_execution_resp.body.execution.execution_id while True: list_executions_request = oos_20190601_models.ListExecutionsRequest( region_id=region_id, execution_id=execution_id ) list_executions_resp = client.list_executions(list_executions_request) status = list_executions_resp.body.executions[0].status if status == FAILED: status_message = list_executions_resp.body.executions[0].status_message raise exception.OOSExecutionFailed(reason=status_message) elif status in END_STATUSES: return list_executions_resp.body time.sleep(1) @tools.append
