Implementation Reference

• server_monitor/tools/system_tools.py:11-24 (handler)

  Core handler function implementing the get_memory_info tool using psutil.virtual_memory() to retrieve and format local server memory information.

  @handle_exceptions
  def get_memory_info() -> dict:
      """获取本地服务器内存信息"""
      mem = psutil.virtual_memory()
      return {
          "status": "success",
          "total": mem.total,
          "used": mem.used,
          "free": mem.free,
          "usage": mem.percent,
          "available": mem.available,
          "cached": getattr(mem, 'cached', 0),
          "buffers": getattr(mem, 'buffers', 0)
      }

• server_monitor_sse/tools/system_tools.py:11-24 (handler)

  Identical core handler function for get_memory_info tool in the SSE variant, using psutil to get memory stats.

  @handle_exceptions
  def get_memory_info() -> dict:
      """获取本地服务器内存信息"""
      mem = psutil.virtual_memory()
      return {
          "status": "success",
          "total": mem.total,
          "used": mem.used,
          "free": mem.free,
          "usage": mem.percent,
          "available": mem.available,
          "cached": getattr(mem, 'cached', 0),
          "buffers": getattr(mem, 'buffers', 0)
      }

• server_monitor/main.py:42-65 (registration)

  Registration of the get_memory_info tool (line 43) within the tools_dict used to dynamically register all tools with the MCP server instance.

  tools_dict = {

  }
  
  # 使用装饰器动态注册所有工具
  for name, func in tools_dict.items():
      mcp.tool()(func)

• server_monitor/models/schemas.py:107-107 (schema)

  Enum constant defining the tool name 'get_memory_info' in ServerTools for schema/reference purposes.

  MEMORY_INFO = "get_memory_info"

• server_monitor/tools/utils.py:44-44 (helper)

  Hardcoded tool description entry for get_memory_info in the list_available_tools helper function.

  {"name": "get_memory_info", "description": "获取本地服务器内存信息", "parameters": []},
