PRIMCS

Enables LLM agents to safely execute arbitrary Python code in a secure, throw-away sandbox.

About

PRIMCS functions as a lightweight, open-source Model Context Protocol (MCP) server specifically designed to empower LLM agents. It provides a secure environment for agents to execute arbitrary Python code, with each execution occurring within a fresh, isolated, and throw-away sandbox. This ensures safe and reproducible code execution for AI applications, handling dependency installation and workspace cleanup automatically.

Key Features

  • Exposes a single `run_code` MCP tool for Python execution
  • Provides isolated and reproducible execution environments with fresh virtual-envs
  • Offers zero-configuration setup and easy deployment via Docker or direct execution
  • Streams `stdout` and `stderr` back from executed code
  • 1 GitHub stars

Use Cases

  • Facilitating AI agent interaction with external systems and APIs through code execution
  • Enabling LLM agents to execute arbitrary Python code securely within a sandbox
  • Providing a safe environment for AI-driven code generation, testing, and debugging
