Description

PRIMS is a lightweight open-source Model Context Protocol server designed to run Python code safely in throw-away virtual environments. It provides a single tool, run_code, to execute user-supplied Python code with streaming output, supports mounting files and installing pip packages per session, and cleans up after execution to ensure isolation and reproducibility. The server can be run locally or via Docker with zero configuration, making it easy to integrate with LLM agents for dynamic code execution.
