Implementation Reference

• complete_fastmcp_server.py:210-229 (handler)

  MCP tool handler function for 'describe_rds_instances'. It is decorated with @app.tool() for registration and implements logic by attempting to delegate to a matching function in common_api_tools.tools (though none matches), falling back to an availability message.

  @app.tool()
  def describe_rds_instances(region: str = "cn-beijing") -> str:
      """查询RDS实例列表
      
      Args:
          region: 区域ID，如cn-beijing
      """
      try:
          sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'alibaba_cloud_ops_mcp_server'))
          from tools import common_api_tools
          
          for tool_func in common_api_tools.tools:
              if hasattr(tool_func, '__name__') and 'rds' in tool_func.__name__.lower() and 'describe' in tool_func.__name__.lower():
                  result = tool_func(RegionId=region)
                  return str(result)
          
          return f"RDS实例查询功能可用，查询region: {region}"
      except Exception as e:
          return f"RDS查询失败: {str(e)}"

• alibaba_cloud_ops_mcp_server/config.py:22-24 (helper)

  Configuration listing supported APIs for RDS service, including 'DescribeDBInstances', likely used by common API tools to understand available operations.

  'rds': [
      'DescribeDBInstances'
  ]

• alibaba_cloud_ops_mcp_server/tools/common_api_tools.py:66-75 (helper)

  Generic helper tool 'CommonAPICaller' in common_api_tools that can call RDS APIs like DescribeDBInstances, which the handler attempts to delegate to (though name matching fails).

  def CommonAPICaller(
          service: str = Field(description='AlibabaCloud service code'),
          api: str = Field(description='AlibabaCloud api name'),
          parameters: dict = Field(description='AlibabaCloud ECS instance ID List', default={}),
  ):
      """
      Use PromptUnderstanding tool first to understand the user's query, Perform the actual call by specifying the Service, API, and Parameters
      """
      return _tools_api_call(service, api, parameters, None)
