## Description

MCP Code Sandbox provides secure, isolated environments for executing Python code through multiple backend options including E2B and Firecracker microVMs. Built with a modular architecture, it offers tools for sandbox creation, code execution, file operations, package installation, and data visualization through chart generation. The implementation features an abstract interpreter interface that allows seamless switching between execution backends, robust error handling, and resource cleanup mechanisms. This server is particularly valuable for AI assistants that need to run untrusted code, test programming solutions, generate data visualizations, or interact with files in a controlled environment without security risks.
