  4. Use it in a session

    Ask Claude to use the tools this server exposes. It discovers them automatically.

What tools does PyMemoryEditor expose?

This server runs as a local package. We only query remote servers for their tool list — asking this one would mean executing it, so its tools are listed in the documentation below.

What the code can do

Source analysis currently covers npm packages only. This server ships as a Python package, which needs a different parser.

Documentation

Full README

PyMemoryEditor

A pure-Python library (built on ctypes) that lets you inspect, modify and search the memory of any running process in a few lines of Python — Cheat Engine workflows on Windows, Linux and macOS!


<b>Read, write and scan the memory of any process — straight from Python.</b> <i>One unified API. Three operating systems. No C compiler. No native build step.</i>

Runs on <b>Windows</b> · <b>Linux</b> · <b>macOS</b> — 32-bit and 64-bit.

Tweak a value in a running game · inspect a live program's state · harvest data straight from RAM.


Install

bash
pip install PyMemoryEditor

To also install the bundled GUI app (a Cheat Engine-style scanner), use the app extra:

bash
pip install "PyMemoryEditor[app]"
pymemoryeditor

For faster scans on large processes, add the speed extra. It pulls in NumPy and automatically vectorizes the numeric scan comparison loop — ~10–30× faster on selective scans:

bash
pip install "PyMemoryEditor[speed]"

To let an AI assistant drive the library over the Model Context Protocol, use the mcp extra (see below):
