Node Code Sandbox MCP

🚀 Node.js Sandbox MCP Server

This is a Model Context Protocol (MCP) server implemented in Node.js. It's designed to run arbitrary JavaScript within ephemeral Docker containers and supports dependency injection.

🚀 Quick Start

This Node.js MCP server enables seamless execution of JavaScript in Docker containers, with features like dependency injection and compatibility with AI tools.

✨ Features

• MCP Compatibility: Complies with the Model Context Protocol standard, allowing seamless integration with AI tools such as Claude.
• Docker Integration: Runs and manages containers via Docker, ensuring environment isolation and resource control.
• Dependency Injection: Supports mounting the host's Docker socket and other volumes into containers, facilitating complex task execution.
• Persistent Output: Allows saving container output results to a specified directory on the host for easy user access and management.
