Node.js Code Sandbox

This MCP server provides secure Node.js code execution in isolated Docker containers with automatic dependency management, file system persistence, and resource monitoring capabilities. Built by mozicim using TypeScript, it creates ephemeral or persistent sandbox environments that can install npm packages, execute JavaScript code with configurable timeouts and resource limits, handle file I/O operations with automatic change detection, and optionally expose HTTP servers on specified ports. The implementation features container lifecycle management with automatic cleanup, npm package caching for faster subsequent runs, comprehensive telemetry reporting including execution times and resource usage, and integration with AI code generation tools through Gemini API, making it valuable for AI-powered development workflows, code experimentation, educational environments, and building assistants that need to execute and test JavaScript code safely.
