Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "x64dbg": {
      "command": "npx",
      "args": [
        "-y",
        "x64dbg-mcp-server"
      ],
      "env": {
        "X64DBG_MCP_HOST": "your-value",
        "X64DBG_MCP_PORT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add x64dbg --env X64DBG_MCP_HOST=your-value --env X64DBG_MCP_PORT=your-value -- npx -y x64dbg-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "x64dbg": {
      "command": "npx",
      "args": [
        "-y",
        "x64dbg-mcp-server"
      ],
      "env": {
        "X64DBG_MCP_HOST": "your-value",
        "X64DBG_MCP_PORT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "x64dbg": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "x64dbg-mcp-server"
      ],
      "env": {
        "X64DBG_MCP_HOST": "your-value",
        "X64DBG_MCP_PORT": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Values you fill in

X64DBG_MCP_HOST env
Host where the x64dbg plugin REST API listens
X64DBG_MCP_PORT env
Port where the x64dbg plugin REST API listens

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is X64dbg safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.3.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

x64dbg MCP Server

Drive [x64dbg](https://x64dbg.com/) 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.

Download the v2.3.0 plugins →

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.

Install

1 · Plugin (inside x64dbg)

Download x64dbg_mcp.dp64 / .dp32 from the latest release and drop them in:

x64dbg/x64/plugins/x64dbg_mcp.dp64    ← 64-bit targets

x64dbg/x32/plugins/x64dbg_mcp.dp32 ← 32-bit targets

…or build + install it yourself (auto-detects your x64dbg — no path editing):

.\build.ps1 -Install

Start x64dbg; the log shows [MCP] x64dbg MCP Server started on 127.0.0.1:27042.

2 · Server (your AI client)

No install — just point your client at npx. Claude Code:

"mcpServers": { "x64dbg": { "type": "stdio", "command": "cmd", "args": ["/c", "npx", "-y", "x64dbg-mcp-server"] } } }

Claude Desktop / Cursor / Windsurf / Cline use the same block without the cmd /c wrapper: { "command": "npx", "args": ["-y", "x64dbg-mcp-server"] }. Full per-client paths are in the reference.

3 · Go

Open a target in x64dbg and start talking to your assistant.

Tools at a glance

23 action-based tools spanning the whole debugger:

Control — run/step/pause, raw commands, scripts, expression eval
CPU & memory — registers (incl. AVX-512), read/write/alloc/protect, memory map
Stack — call stack, SEH chain, return addresses
Code analysis — disassemble, assemble, xrefs, basic blocks, CFG, loops
Breakpoints & tracing — software/hardware/memory/conditional/logging, batch, trace logs
Symbols & search — labels, comments, bookmarks, AOB pattern + string scan
Process & system — threads/TEB, handles, TCP, PEB, anti-debug hide
Patching & dumping — byte patches, PE dump, IAT fix, patch export

Every tool, action, and endpoint is documented in [docs/REFERENCE.md](docs/REFERENCE.md).

Security

The plugin binds to 127.0.0.1 only; the server talks pure stdio. All traffic stays on localhost — no remote access, no telemetry, no data leaves your machine. For defense against other local processes, set a token in the plugin's Settings and pass it via X64DBG_MCP_TOKEN — every request must then carry it.
