Lightweight and portable LLM sandbox runtime (code interpreter) Python library.
LLM Sandbox is a Python library and MCP server for running code generated by large language models inside isolated containers. It is used when AI-generated programs need controlled access to languages, dependencies, computing resources, or networks without directly reaching the host system. The catalogue add-ons help agents use the sandbox.
This repository also configures its own agents. See what llm-sandbox tells them →
