Implementation Reference

• complete_fastmcp_server.py:165-183 (handler)

  The handler function decorated with @app.tool() that implements the describe_vpcs tool. It dynamically imports common_api_tools and searches for a tool function containing 'vpc' in its name to delegate the RegionId call, or returns an availability message.

  @app.tool()
  def describe_vpcs(region: str = "cn-beijing") -> str:
      """查询VPC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 'vpc' in tool_func.__name__.lower():
                  result = tool_func(RegionId=region)
                  return str(result)
          
          return f"VPC查询功能可用，查询region: {region}"
      except Exception as e:
          return f"VPC查询失败: {str(e)}"

• alibaba_cloud_ops_mcp_server/config.py:18-20 (helper)

  Configuration listing the DescribeVpcs API under the Vpc service, likely used to dynamically generate tool functions in api_tools.create_api_tools.

  'Vpc': [
      'DescribeVpcs',
      'DescribeVSwitches'

• alibaba_cloud_ops_mcp_server/server.py:70-70 (registration)

  Calls create_api_tools with the config to register dynamic API tools, including VPC_DESCRIBE_VPCS (note: different name from describe_vpcs).

  api_tools.create_api_tools(mcp, config)

• alibaba_cloud_ops_mcp_server/tools/api_tools.py:234-238 (helper)

  Function that dynamically creates and registers MCP tools for each API in the config, naming them like 'VPC_DESCRIBE_VPCS'. The describe_vpcs might be a wrapper or alias.

  def create_api_tools(mcp: FastMCP, config:dict):
      for service_code, apis in config.items():
          for api_name in apis:
              _create_and_decorate_tool(mcp, service_code, api_name)
