MCP System Info Server

A lightweight MCP (Model Context Protocol) server that provides real-time system information including CPU, memory, disk, and GPU statistics.

Features

Category	Information Provided
System	System name, node name, OS release/version, machine type, processor
CPU	Processor name, physical/logical cores, frequency, usage percentage
Memory	Total, available, used memory (GB), utilization percentage
Disk	Total, used, free space (GB), utilization percentage
GPU	Name, memory (total/used/free), utilization, temperature (NVIDIA only)

Prerequisites

• Python 3.10+
• uv - Fast Python package manager

Installation

# Clone or navigate to the project directory
cd mcp

# Install dependencies (handled automatically by uv)
uv sync
