Deno Sandbox MCP Server is an MCP server that allows you to run TypeScript, JavaScript, and Python code in a sandbox on your local machine using the Deno® sandbox.

The Deno Sandbox MCP Server provides a secure environment for executing code by leveraging the Deno runtime, which uses the same technology as Chrome to prevent malicious activities. It supports TypeScript, JavaScript, and Python execution, with explicit permission controls to manage file access and network connectivity. This server is particularly useful for testing code generated by LLMs, ensuring that potentially harmful operations are restricted. The server is designed to be simple and auditable, prioritizing security and ease of understanding over performance. It uses Pyodide for running Python code within the Deno environment, allowing for a consistent sandboxing experience across different programming languages.

Features

  • Supports TypeScript, JavaScript, and Python execution in a sandboxed environment.
  • Explicit permission controls for file access and network connectivity.
  • Uses Deno runtime for secure code execution, similar to Chrome's security model.
  • Simple and auditable codebase for easy understanding and bug detection.
  • Integration with Pyodide for running Python code in the same environment.
