Implementation Reference

• sysinfo.py:9-18 (handler)

  The tool handler function for 'get_sysinfo', decorated with @mcp.tool() for registration, fetches system info asynchronously and returns it as a formatted string.

  @mcp.tool()
  async def get_sysinfo() -> str:
      """Get the current system information.
      Gives system information such as System, Node name, Release, Version, Machine, Processor
      CPU Information such as Processor, Physical Cores, Logical Cores
      Memory Information such as Total Memory, Available Memory, Used Memory, Memory Utilization
      Disk Information such as Total Disk Space, Used Disk Space, Free Disk Space, Disk Space Utilization
      """
      data = await get_system_info()
      return data

• fetch_info.py:6-59 (helper)

  Supporting utility function that gathers comprehensive system information (CPU, memory, disk) using platform and psutil libraries, formats it into a multi-line string, and returns it. Called by the tool handler.
