JavaScript Sandbox
This JavaScript sandbox MCP server, developed by an unknown author, provides a secure environment for executing JavaScript code within defined constraints. Built with TypeScript and leveraging the Model Context Protocol SDK, it offers a tool for running arbitrary JavaScript with configurable time and memory limits. The implementation focuses on isolation and security, utilizing the vm2 library to create a controlled execution context. It's particularly useful for tasks like code testing, algorithm evaluation, or providing a safe playground for AI models to experiment with JavaScript, enabling assistants to execute and analyze JavaScript code without risking system integrity or resource exhaustion.
