PRIMS

Acerca de

PRIMS is a lightweight, open-source Model Context Protocol (MCP) server designed to provide LLM agents with a safe and secure environment for executing arbitrary Python code. It streamlines development by offering a single, focused `run_code` tool that operates within isolated, reproducible sandboxes. Each execution session spins up a fresh virtual environment, handles package installations, mounts optional read-only files, and then disposes of the workspace, all with zero configuration, making it easy to deploy locally or with Docker.

Características Principales

• Supports installing pip packages and mounting remote files per session.
• Streams `stdout` and `stderr` back from executed code.
• Provides isolated and reproducible execution environments using virtual environments.
• 7 GitHub stars
• Exposes a single `run_code` MCP tool for Python execution.
• Enables persisting generated artifacts to external storage.

Casos de Uso

• Generating and persisting outputs like plots or data files from agent-executed code.
• Analyzing datasets by mounting them into the execution environment.
• Allowing LLM agents to safely run Python code for complex tasks.
