Linux Mcp

linux-mcp - Linux MCP Server

A Linux system monitoring server built on the Model Context Protocol (MCP). Provides real-time system information - CPU, memory, disk, network, processes, Docker, and more - via MCP tools over STDIO transport.

Features

• System - hostname, OS, kernel, architecture, uptime, load averages
• CPU - usage, model, frequency, core counts, temperature sensors
• Memory - RAM and swap usage with percentages
• Disk - per-partition usage, inodes, mount options, largest files, block devices
• Network - interface stats, active connections, listening ports, DNS, ping, IP geolocation & ASN lookup
• Processes - running processes sorted by CPU or memory, open file descriptors per process
• Docker - containers, images, networks, volumes, disk usage, system info, and container stats
• Services & automation - systemd units, service status, user timers, crontab, system cron jobs
• Security - active user sessions, failed login detection, SELinux/AppArmor status, firewall/SSH/SUID/world-writable audit with security score
• Packages - installed packages and available updates (pacman, dpkg, rpm/dnf, apk)
• Hardware - GPU info, PCI/USB bus devices, power/battery analytics
• Desktop session - Wayland/X11 protocol, DE identifiers, runtime config
• Storage health - RAID status, logrotate configuration, time synchronization, SMART disk health, per-device I/O metrics
• System health - comprehensive health assessment with memory, disk, load, and systemd checks
• /proc diagnostics - deep /proc inspection: interrupts, softirqs, vmstat, diskstats, filesystems, kernel version, slabinfo
• Man pages - system manual pages for any installed command
• Snapshot - comprehensive system overview in a single call
• MCP Resources - system data also accessible as readable resources

Prerequisites

• Go 1.27+ (to build from source)
• Linux (the server targets Linux; some tools use Linux-specific paths)
• Docker (optional - only needed for Docker tools)

Installation

Via MCP Registry

Discover the server on the MCP Registry and install via your MCP client (VS Code one-click install, or manual config).

Download pre-built binary

Download the latest binary from the GitHub Releases page:

curl -LO https://github.com/Mohabdo21/linux-mcp/releases/latest/download/linux-mcp
chmod +x linux-mcp

A fully static build (no libc dependency) is also available as linux-mcp_static.

Via go install

go install github.com/Mohabdo21/linux-mcp@latest

The binary is placed in $GOPATH/bin/ (typically ~/go/bin/).

Build from source

git clone https://github.com/Mohabdo21/linux-mcp.git
cd linux-mcp
make build

The binary is placed at bin/linux-mcp.

For a fully static binary (no libc dependency):

make build-static

Usage

The server communicates over STDIO transport, following the MCP standard. It is designed to be launched by an MCP client (e.g., Claude Desktop, Claude Code, Codex, OpenCode, or any MCP host).

Running directly

./bin/linux-mcp

This starts the server and listens for MCP requests on STDIN/STDOUT.

Tools and resources

65 tools and 19 resources covering system, CPU, memory, disk, network, processes, Docker, security, packages, hardware, and more.

Configuration

The server can be configured via a JSON file loaded from ~/.config/linux-mcp/config.json or the LINUX_MCP_CONFIG environment variable.

{
  "log_level": "info",
  "timeouts": {
    "get_system_snapshot": "60s",
    "ping_host": "5s"
  },
  "disabled": []
}

The server also handles SIGHUP to reload the configuration file at runtime without restarting.
