sandbox-mcp

Overview

Sandbox MCP is a Model Context Protocol server that allows LLMs to safely execute code in isolated Docker environments. It provides a secure sandbox for testing code without risking the host system, supporting multiple programming languages and specialized environments. The project actively maintains various pre-configured sandboxes including Python, Rust, Go, JavaScript, and network tools, making it highly versatile for different use cases.
