## Description

Node Code Sandbox MCP Server provides a secure Docker-based environment for executing Node.js code through the MCP protocol. It enables AI assistants to initialize sandboxed containers, run JavaScript with npm dependencies, execute shell commands, and manage file operations with proper isolation. The server supports ephemeral execution, port forwarding for web applications, and includes resource limits to prevent abuse. Built with TypeScript and compatible with various MCP clients like Claude Desktop and VS Code, it's ideal for code testing, web development prototyping, and educational demonstrations without compromising host system security.
