Code Runner

Executes code snippets in isolated Docker containers with resource limits and security controls for safe testing and debugging across multiple programming languages.

MCP Code Runner is a TypeScript server that enables AI assistants to execute code snippets in isolated Docker containers. Developed by axliupore, it supports multiple programming languages including Python, JavaScript, TypeScript, Go, Java, C, and C++. The implementation uses Dockerode to manage container lifecycle, enforces resource limits (memory, CPU) and network isolation for security, and returns execution results with stdout/stderr output. It's particularly useful for code testing, debugging, and educational scenarios where safe execution of untrusted code is required.
