PyMemoryEditor MCP server

PyMemoryEditor

<!-- mcp-name: io.github.JeanExtreme002/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!

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

Runs on Windows · Linux · macOS — 32-bit and 64-bit.

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

Install

pip install PyMemoryEditor

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

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:

pip install "PyMemoryEditor[speed]"

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

pip install "PyMemoryEditor[mcp]"

See it in action

from PyMemoryEditor import OpenProcess

with OpenProcess(name="game.exe") as process:

    # Scan the whole process for every address holding the value 100.
    for address in process.search_by_value(int, value=100):
        print(f"Found at 0x{address:X}")

    # Read the current value, then write a new one back.
    current = process.read_int(address)
    process.write_int(address, current + 500)

That's it — read, write or scan another process in three lines, the same way on every platform.

Let an AI assistant do it (MCP)

PyMemoryEditor ships a Model Context Protocol server, so an AI assistant can run the whole loop itself:

"Find the health value in my game. It's 100 right now."

It scans, asks you to take damage, refines the matches, and hands you the address.

pip install "PyMemoryEditor[mcp]"
claude mcp add pymemoryeditor -- pymemoryeditor-mcp
