x64dbg MCP servers: which one to use
x64dbg has no official MCP server. Use duty1g for the most stars, or bromoket if you want a one-line npx setup over stdio.

x64dbg has no official MCP server, so all six options here are community projects for the Windows debugger. Each one runs on your own machine and lets your assistant set breakpoints, read memory and step through code. These servers can change a live process. duty1g says its server has full debugger control and can read and write process memory, and SetsunaYukiOvO keeps memory writes, register writes and script execution off until you turn them on. Start with duty1g, which has the most stars, and pick another if your client needs stdio.
Good for
- Reverse engineers who want an assistant to set breakpoints, read memory and explain disassembly in x64dbg
- Malware analysts tracing or unpacking a sample on a Windows machine
- Claude Code or Cursor users who want a quick install
- Anyone who needs memory and register writes switched off by default
Which x64dbg MCP server to use
Use duty1g for the most stars, or bromoket if you want your client to start it with npx. Use SetsunaYukiOvO if you want memory writes and script execution off until you enable them.

Questions
Is there an official x64dbg MCP server?
No. The x64dbg GitHub organization lists no MCP server, so every option is a community project. duty1g's x64dbg-MCP Server has the most stars.
Which x64dbg MCP server should I start with?
Start with duty1g. It has the most stars, an MIT license, and a bearer token that is generated on first run and required on every request. Its README lists 84 tools in the feature list and 72 in the tools section. Pick bromoket instead if you want your client to start it with npx over stdio.
Is it safe to let an assistant drive a debugger?
Treat it as a tool that can change a running process. duty1g says its server can read and write process memory, and warns not to expose it to untrusted networks because it speaks unencrypted HTTP. SetsunaYukiOvO keeps memory writes, register writes and script execution off by default.
Does it work on Mac or Linux?
Not natively. The ouonet README says it needs Windows because x64dbg is Windows-only, and SetsunaYukiOvO lists Windows 10/11 as the host. Run it on a Windows PC or in a Windows virtual machine.
Does it work with Claude and Cursor?
Yes. bromoket shows a Claude Code setup, AgentSmithers shows a Cursor setup, and Wasdubya shows a Claude Desktop setup. AgentSmithers says Claude Desktop needs a separate stdio-to-SSE bridge.
Do these run locally or in the cloud?
Locally. Each one is a plugin or bridge on the same machine as x64dbg. bromoket says its plugin binds to 127.0.0.1 only and that nothing leaves your machine.
What is the difference between duty1g and bromoket?
duty1g is a native plugin that serves MCP over HTTP, and your client connects with a URL and token. bromoket is a plugin plus a small TypeScript bridge that your client starts over stdio, with 23 tools that cover 153 endpoints.
Are they free?
Yes. All six are public GitHub projects you can download. duty1g, SetsunaYukiOvO, bromoket and ouonet are MIT licensed, and Wasdubya is GPL-3.0.
