MCP.Pizza Chef: Wasdubya

Reverse engineers and malware analysts can ask an assistant to read registers, search a loaded module for a byte pattern, set breakpoints, inspect memory, and walk through a program paused under the debugger, with more than forty debugger features available. Installing means copying a plugin file into your x64dbg folder, adding two Python packages, and pasting a short block into your app's settings. Windows only. Free, and last updated in June 2026.

x64dbgMCP FAQ

Is this still maintained?
Yes. The most recent commits landed in June 2026, and both 32-bit and 64-bit plugin builds are provided.
Which apps does it work in?
Claude Desktop and Cursor are both tested, and other MCP-capable tools should work too.
Do I need a paid key?
No. It is free, but you do need x64dbg installed on a Windows machine.
Can I use this to inspect a running program's memory?
Yes. Reading registers, memory, and module information is its main job.
How hard is setup?
Hands-on. Copy a plugin file into x64dbg, install two Python packages, then edit your app's settings file.
Does it work on Mac or Linux?
No. x64dbg is a Windows debugger, so this is Windows only.
