Frequently asked questions

What are the runtime requirements?

Python 3.12 or higher and the uv package manager (recommended) or pip.

How can I run the server without installing anything?

Use `uvx python-runner` directly. This requires no prior installation.

Is it safe to execute arbitrary code?

Code runs in isolated namespaces and output is captured separately. However, the tool does execute arbitrary Python code; only use it in a trusted environment.

How do I call the server from Python directly?

After manual installation, import `execute_python` from `main` and pass a code string. The function returns a dict with `output`, `error`, and `success` keys.
