# Code Runner

> Use this tool when you need to execute untrusted code snippets in a secure environment, supporting multiple programming languages, to solve problems related to code testing, debugging, and education. It takes in code snippets as input and returns execution results with stdout/stderr output, while enforcing resource limits and network isolation for security. Ideal for use cases where safe execution of unknown code is required, such as educational platforms or code review tools.

## Description

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.
