MCP ProcFS Server - Project Summary

Overview

A production-ready Model Context Protocol (MCP) server that provides comprehensive access to Linux /proc filesystem and system management capabilities. Supports both JSON-RPC over stdio and HTTP with Server-Sent Events (SSE).

Features Implemented

Core Functionality

✅ ProcFS Reading

• CPU information (/proc/cpuinfo)
• Memory statistics (/proc/meminfo)
• Load average (/proc/loadavg)
• Network interface statistics (/proc/net/dev)
• Disk I/O statistics (/proc/diskstats)
• Process information (/proc/[pid]/)
• Raw file reading from any /proc path

✅ ProcFS Writing

• Write to writable /proc files
• Kernel parameter management via sysctl
• Process priority adjustment (nice values)
• CPU affinity configuration
• OOM score adjustment
• Process signal sending

✅ MCP Protocol

Security Considerations

⚠️ Important:

• Provides direct system access
• Write operations require appropriate permissions
• Should implement authentication for production
• Consider read-only mode for untrusted clients
• Monitor and log all operations

Testing

npm test              # Run tests
npm run test:watch    # Watch mode
npm run test:coverage # Coverage report

Current: 10 passing tests covering core functionality
