Overview

What is Node Code Sandbox MCP?

Node Code Sandbox MCP provides a secure JavaScript execution environment tailored for AI applications. It allows coding agents and large language models (LLMs) to run JavaScript dynamically, install NPM packages, and retrieve results, all while adhering to the Model Control Protocol (MCP).

How to use Node Code Sandbox MCP?

Clone the repository, run npm install and npm start to start the server. Open http://localhost:3000 in a browser, input JavaScript code, and click "Run" to execute it. Alternatively, use the /execute and /install API endpoints. Packages can be installed via the interface command npm install <package-name> or the /install endpoint.

Key features of Node Code Sandbox MCP

  • Dynamic JavaScript execution in a secure sandbox
  • NPM package installation and usage on demand
  • MCP compatibility for seamless AI agent integration
  • Sandboxing prevents unauthorized access and ensures safety
  • Interactive code generation and testing via web interface

Use cases of Node Code Sandbox MCP

  • Code generation and validation for LLM-based coding assistants
  • Dynamic script execution in AI-driven development workflows
  • Safe testing and prototyping of JavaScript snippets with dependencies
  • Interactive assistance where LLMs need to run and inspect JS code

FAQ from Node Code Sandbox MCP

What are the prerequisites for using Node Code Sandbox MCP?

Node.js (version 14 or higher), NPM, and basic knowledge of JavaScript and AI concepts are required.

How can I install and start the server?

Clone the repository, navigate to the project directory, run npm install, then npm start. The server runs on http://localhost:3000.

What API endpoints are available?

The server provides a POST /execute endpoint to run code (with a code field) and a POST /install endpoint to install NPM packages (with a package field).

Does Node Code Sandbox MCP support NPM packages?

Yes. You can install packages using the npm install <package-name> command in the web interface or via the /install API endpoint.

How does sandboxing protect the host environment?

Sandboxing ensures secure execution to prevent unauthorized access and system compromise during code runs.
