How to install PyMemoryEditor in Claude CodeAnthropic's agentic CLI
Add the server
bashclaude mcp add PyMemoryEditor -- uvx pymemoryeditorVerify it's connected
bashclaude mcp listSharing it with your team?
Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).
Use it in a session
Ask Claude to use the tools this server exposes. It discovers them automatically.
How to install PyMemoryEditor in Claude DesktopDesktop app (MCP config)
Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json
Add this server
json{ "mcpServers": { "PyMemoryEditor": { "command": "uvx", "args": [ "pymemoryeditor" ] } } }Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.
How to install PyMemoryEditor in CursorAI-first code editor
Create / edit .cursor/mcp.json in your project
json{ "mcpServers": { "PyMemoryEditor": { "command": "uvx", "args": [ "pymemoryeditor" ] } } }Enable it
Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.
How to install PyMemoryEditor in Codex CLIOpenAI coding agent
Add to ~/.codex/config.toml
toml[mcp_servers.PyMemoryEditor] command = "uvx" args = ["pymemoryeditor"]Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.
How to install PyMemoryEditor in WindsurfCodeium's agentic IDE
Edit ~/.codeium/windsurf/mcp_config.json
json{ "mcpServers": { "PyMemoryEditor": { "command": "uvx", "args": [ "pymemoryeditor" ] } } }Reload
Windsurf → Cascade → refresh MCP servers. Cascade can now call the tools.
How to install PyMemoryEditor in ClineVS Code autonomous agent
Open Cline → MCP Servers → Configure
Adds to cline_mcp_settings.json.
Add the server

How to install PyMemoryEditor in VS CodeCopilot / MCP support
Create .vscode/mcp.json
json{ "servers": { "PyMemoryEditor": { "type": "stdio", "command": "uvx", "args": [ "pymemoryeditor" ] } } }Start it
VS Code shows a ▶ Start action above the server entry. Agent mode (Copilot Chat) can then use the tools.
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 READMEPyMemoryEditor
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
pip install PyMemoryEditorTo also install the bundled GUI app (a Cheat Engine-style scanner), use the app extra:
pip install "PyMemoryEditor[app]"
pymemoryeditorFor 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):
