Know Your Computer (KYC) System Diagnostics MCP Server is a cross-platform MCP server designed to run with Claude Desktop to deliver in-depth system diagnostics for Windows, macOS, and Linux. It provides comprehensive hardware and system monitoring through 12 diagnostic tools, covering CPU, memory, storage, network, processes, applications, battery, motherboard details, and performance analysis, along with real-time metrics and upgrade recommendations. Core monitoring capabilities include System Information (OS, hardware specs, uptime), Computer Model Detection (manufacturer, model, specs), Motherboard Details (BIOS/UEFI, memory slots), CPU Metrics (usage, frequency, temperature, per-core), Memory Monitoring (RAM/swap usage, per-process), Storage Analysis (disk usage, I/O, SSD/HDD detection), Network Monitoring (interface stats, connections, traffic), Process Management (running processes and resource consumption), Application Inventory, Battery Status (power/battery health), System Logs, Performance Diagnostics (bottlenecks), and Hardware Recommendations. Platform support spans Windows 10/11, macOS 10.15+, Linux (Ubuntu, Debian, RHEL, etc.). Prerequisites are Python 3.8+ and pip; optional Windows-specific dependencies (wmi, pywin32). Claude Desktop integration is configured via JSON files pointing to the Python module. Security focuses on read-only data access and avoiding sensitive data collection.
