sandbox-mcp and node-code-sandbox-mcp
These are complements: pottekkat/sandbox-mcp provides language-agnostic code execution in Docker containers, while mozicim/node-code-sandbox-mcp specializes in JavaScript/Node.js execution, allowing them to be used together for polyglot sandboxing scenarios or as alternatives optimized for different runtime requirements.
About sandbox-mcp
pottekkat/sandbox-mcp
A Model Context Protocol (MCP) server that enables LLMs to run ANY code safely in isolated Docker containers.
Provides pre-configured sandboxes for Python, Rust, Go, JavaScript, Java, and network diagnostics, with support for custom Docker-based environments. Implements MCP's stdio transport protocol to integrate with Claude Desktop and Cursor IDE, allowing LLMs to compile, execute, and test code across multiple languages within ephemeral isolated containers. Configuration is managed locally through simple JSON and Dockerfile definitions, enabling customization without requiring external services.
