What is MCP Python Executor?

MCP Python Executor is a Model Context Protocol (MCP) server that allows AI models and other MCP clients to execute Python code and manage Python packages. It enforces safety constraints, resource limits, and provides health checks and structured logging, making it suitable for controlled code execution environments.

How to use MCP Python Executor?

Configure the server in your MCP settings with the command node path/to/python-executor/build/index.js. Customize behavior via environment variables such as PREINSTALLED_PACKAGES, MAX_MEMORY_MB, EXECUTION_TIMEOUT_MS, and MAX_CONCURRENT_EXECUTIONS. Then use the provided tools—execute_python to run inline or file-based Python code, and install_packages to install Python packages.

Key features of MCP Python Executor

Execute Python code with safety constraints
Install and manage Python packages dynamically
Pre-configure commonly used packages on startup
Resource monitoring with configurable memory and time limits
Health checks and structured logging (JSON or text)

Use cases of MCP Python Executor

Run Python code snippets from an AI assistant to perform calculations or data transformations
Execute pre-existing Python scripts by providing a script path
Install additional Python packages on demand during a session
Manage concurrent code executions with defined memory and timeout limits

FAQ from MCP Python Executor

What kind of Python code can be executed?

Any valid Python code can be run inline via the code parameter or from a file via scriptPath. The server applies memory limits, timeouts, and concurrency restrictions to ensure safe execution.

What are the runtime dependencies?

The server runs on Node.js and requires a Python environment. The specific Python version is not stated in the README; the server attempts to use the system’s default Python.

How do I pre-install packages?

Set the PREINSTALLED_PACKAGES environment variable to a space-separated list of package names (e.g., numpy pandas matplotlib scikit-learn). These are installed on server startup using pip.

What resource limits are enforced?

You can configure per‑execution memory limit (MAX_MEMORY_MB, default 512), timeout (EXECUTION_TIMEOUT_MS, default 30000), and maximum concurrent executions (MAX_CONCURRENT_EXECUTIONS, default 5). No authentication or transport details are specified in the README.

How does logging work?

Logging level and format are controlled by LOG_LEVEL and LOG_FORMAT environment variables, supporting debug, info, error levels and json or text formats.
