Implementation Reference

• src/alibaba_cloud_ops_mcp_server/tools/oos_tools.py:248-264 (handler)

  The handler function OOS_StartRDSInstances starts multiple Alibaba Cloud RDS instances using the OOS template 'ACS-RDS-BulkyStartInstances'. It defines the input schema via Pydantic Fields and calls the helper _start_execution_sync.

  @tools.append
  def OOS_StartRDSInstances(
      InstanceIds: List[str] = Field(description='AlibabaCloud ECS instance ID List'),
      RegionId: str = Field(description='AlibabaCloud region ID', default='cn-hangzhou')
  ):
      """批量启动RDS实例，适用于需要同时管理和启动多台RDS实例的场景，例如应用部署和高可用性场景。"""
  
      parameters = {
          'regionId': RegionId,
          'resourceType': 'ALIYUN::RDS::Instance',
          'targets': {
              'ResourceIds': InstanceIds,
              'RegionId': RegionId,
              'Type': 'ResourceIds'
          }
      }
      return _start_execution_sync(region_id=RegionId, template_name='ACS-RDS-BulkyStartInstances', parameters=parameters)

• src/alibaba_cloud_ops_mcp_server/tools/oos_tools.py:25-48 (helper)

  Helper function that synchronously starts an OOS execution by polling its status until completion or failure. Used by OOS_StartRDSInstances and other OOS tools.

  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)
