## python-interpreter-mcp: A MCP server to run scripts ## Overview A lightweight, experimental MCP server designed to execute arbitrary Python scripts in a structured and reproducible environment. It leverages **[uv](https://github.com/astral-sh/uv)** to run isolated code snippets through subprocesses. ### Tools - `run_script` - Runs the given script with `uv run script.py`. - Input: - `code`(str): Script to be run - Return: The stdout of the given script. ## Configuration ### Usage with OpenAI Agents SDK ```python async with MCPServerStdio( params={ "command": "uvx", "args": ["python-interpreter-mcp"], } ) as server ... ``` ### Usage with Claude Desktop Add this to your `claude_desktop_config.json`: ```json "mcpServers": { "interpreter": { "command": "uvx", "args": ["python-interpreter-mcp"] } } ``` ## How it works - A script string is received by the MCP tool `run_script`. - A hidden folder is created in cwd, and the script is saved as a `.py` file inside it. - The script is then executed using `uv run`, which ensures dependency isolation. - The stdout of the script is captured and returned as the response. ## Usage Warnings **This project is in a very early stage of development.** ### ⚠️ Important notes - It executes arbitrary Python code, which means it can run anything — including malicious or destructive commands. - Use only in trusted, sandboxed environments. - You should always validate, guardrail, or restrict inputs when wiring this into an LLM.
