Implementation Reference
- server.py:233-246 (handler)The handler function that implements get_system_info tool logic, collecting system details using platform and psutil libraries and returning as JSON.
async def get_system_info(self) -> list[types.TextContent]: """Get system information""" info = { "platform": platform.system(), "arch": platform.machine(), "hostname": platform.node(), "cpus": psutil.cpu_count(), "totalMemory": f"{round(psutil.virtual_memory().total / (1024**3))} GB", "freeMemory": f"{round(psutil.virtual_memory().available / (1024**3))} GB", "uptime": f"{round(psutil.boot_time())} seconds", "pythonVersion": sys.version, "currentDirectory": str(Path.cwd()), } return [types.TextContent(type="text", text=json.dumps(info, indent=2))] - server.js:270-291 (handler)The handler function implementing get_system_info tool, gathering Node.js os module system information and returning formatted JSON response.
