How to Set Up and Use x64dbg
x64dbg MCP is a C++ plugin and companion server that bridges the x64dbg debugger with AI assistants through the Model Context Protocol, exposing over 150 debugging capabilities as callable tools. It lets AI clients such as Claude, Cursor, Windsurf, and Cline issue natural-language reverse-engineering instructions that are translated into real debugger actions — setting breakpoints, reading registers, disassembling functions, scanning memory patterns, and dumping PE modules. Security researchers and malware analysts can describe what they want to investigate in plain English and let the AI orchestrate the low-level debugger operations required to answer the question.
Prerequisites
- x64dbg debugger installed (both 32-bit and 64-bit variants if needed)
- Windows operating system (x64dbg is Windows-only)
- Node.js 18 or later (to run the MCP server component via npx)
- An MCP-compatible AI client: Claude Desktop, Claude Code, Cursor, Windsurf, or Cline
- Optional: an authentication token configured in the x64dbg plugin settings for secure local communication
Download and install the x64dbg plugin
Download the latest x64dbg_mcp.dp64 (and .dp32 for 32-bit targets) from the GitHub releases page. Place each file in the corresponding x64dbg plugins directory.
# 64-bit plugin path
C:\x64dbg\x64\plugins\x64dbg_mcp.dp64
# 32-bit plugin path
C:\x64dbg\x32\plugins\x64dbg_mcp.dp32Alternative: build and install with PowerShell
If you prefer to build from source, clone the repository and run the install script, which auto-detects your x64dbg installation path.
git clone https://github.com/bromoket/x64dbg_mcp
cd x64dbg_mcp
.\build.ps1 -InstallLaunch x64dbg and open a target binary
Start x64dbg and load the binary you want to analyze. The plugin initializes automatically and starts a local MCP server on 127.0.0.1:27042. Confirm activation in the x64dbg log pane.
Configure your AI client to connect
Add the x64dbg MCP server entry to your client configuration. The server-side component runs via npx and communicates over stdio.
Set an optional authentication token
In x64dbg, open the plugin settings and create an auth token. Pass it as the X64DBG_MCP_TOKEN environment variable in your client config to secure the local connection.
x64dbg Examples
Client configuration
Add this entry to your MCP client configuration file. All traffic stays on localhost — no external network access is required.

}Prompts to try
With x64dbg running and a binary loaded, ask the AI to drive the debugging session.
- "Set a breakpoint on CreateFileW and run the program until it hits, then show me the call stack."
- "Disassemble the current function and explain what it does in plain English."
- "Scan memory for the pattern 48 8B 05 and list all matches with their virtual addresses."Troubleshooting x64dbg
Plugin does not appear in x64dbg after copying the .dp64 file
Verify you placed x64dbg_mcp.dp64 in the x64/plugins/ directory (not x32/plugins/). Restart x64dbg and check the Plugins menu. Also confirm the file is not blocked by Windows — right-click the file, open Properties, and unblock it if a security warning appears.
AI client cannot connect — 'server not running' error
The MCP server only starts after x64dbg opens a target binary. Load a binary in x64dbg first, then reconnect your AI client. Check the x64dbg log pane to confirm the server started on 127.0.0.1:27042.
Authentication token mismatch errors
Copy the token exactly as shown in the x64dbg plugin settings — it is case-sensitive. Paste it verbatim into the X64DBG_MCP_TOKEN env var in your client config, then restart the client.
