Implementation Reference

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

  Primary handler implementation for the 'get_memory_info' MCP tool. Uses psutil to fetch detailed local server memory statistics including total, used, free, usage percentage, available, cached, and buffers.
  @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 handler implementation for the 'get_memory_info' tool in the SSE variant codebase.
  @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:42-66 (registration)

  Registration of the get_memory_info tool (line 43) into the MCP server's tools_dict and subsequent dynamic registration loop using mcp.tool() decorator.
  tools_dict = { 'get_memory_info': get_memory_info, 'remote_server_inspection': remote_server_inspection, 'get_system_load': get_system_load, 'monitor_processes': monitor_processes, 'check_service_status': check_service_status, 'get_os_details': get_os_details, 'check_ssh_risk_logins': check_ssh_risk_logins, 'check_firewall_config': check_firewall_config, 'security_vulnerability_scan': security_vulnerability_scan, 'backup_critical_files': backup_critical_files, 'inspect_network': inspect_network, 'analyze_logs': analyze_logs, 'list_docker_containers': list_docker_containers, 'list_docker_images': list_docker_images, 'list_docker_volumes': list_docker_volumes, 'get_container_logs': get_container_logs, 'monitor_container_stats': monitor_container_stats, 'check_docker_health': check_docker_health } # 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/tools/utils.py:44-44 (schema)

  Descriptive schema for the get_memory_info tool used in list_available_tools function, specifying name, description, and empty parameters.
  {"name": "get_memory_info", "description": "获取本地服务器内存信息", "parameters": []},
• server_monitor/models/schemas.py:107-107 (schema)

  Enum constant defining the tool name 'get_memory_info' in ServerTools enum for reference.
  MEMORY_INFO = "get_memory_info"
