## Description

This code execution server enables AI assistants to run Python and bash code in isolated Docker containers or virtual machines, providing a secure sandboxed environment for code execution tasks. Built with FastMCP and Docker integration, it supports both ephemeral containers (created from images) and persistent named containers, with configurable timeouts and environment variables. The implementation includes a Kali Linux-based container with pre-installed security tools and scientific packages, making it particularly useful for cybersecurity analysis, data science workflows, and general-purpose code execution where isolation and security are paramount.
