Control the x64dbg debugger using natural language through your AI assistant. You can set breakpoints, read and write memory, disassemble code, trace execution, bypass anti-debug protections, and dump executable files. It works locally with apps like Claude, Cursor, Windsurf, and Cline. Setup requires installing a small plugin in x64dbg and adding a simple config snippet to your AI client. No internet or accounts needed, keeping your debugging secure and private.

README

x64dbg MCP Server

npm version MCP Registry License: MIT

Drive x64dbg with your AI. Talk to Claude, Cursor, Windsurf, Cline, or any MCP client in plain English and it sets breakpoints, reads memory, disassembles, traces, dumps PEs, and bypasses anti-debug — live, inside the debugger.

23 mega-tools over 153 REST endpoints, fully typed with Zod. A C++ plugin runs inside x64dbg; a tiny TypeScript server bridges it to your client over stdio. Everything stays on 127.0.0.1 — nothing leaves your machine.

Latest — v2.3.0

  • Hardened & crash-proof. A malformed HTTP request can no longer crash x64dbg; the plugin server drains connections cleanly on stop and ships an optional auth token (CORS is locked down).
  • Real data from more tools. imports/exports, symbols search/list, patches list, and strings now return actual parsed results instead of pointing you at a GUI view.
  • Live trace status. New /api/trace/status (+ tracing status) reports whether a trace is running, and the exception/trace tools now honor every parameter they accept.
  • Plus the v2.2.x fixes: x32dbg loads on current snapshots, and requests no longer time out on long operations.

What it looks like

"Set a breakpoint on CreateFileW and run the program"
"Disassemble the current function and explain what it does"
"Search for 48 8B ?? 48 85 C0 in the main module and disassemble the hits"
"Hide the debugger and bypass the anti-debug checks"
"Trace into the VM dispatcher and log every instruction to a file"
"Dump the main module to disk and fix the import table"

Real use: tracing VMProtect'd code, finding anti-cheat scanner threads, decoding XOR'd class names, mapping detection logic — all by asking, no manual scripting.
