x64dbg-MCP Server Lets AI Agents Drive Windows Debuggers Autonomously
A new Zig-built plugin turns x64dbg into an MCP endpoint, letting Claude and other AI agents drive reverse engineering sessions through 71 tools.
PRO- x64dbg-MCP Server exposes the x64dbg debugger to any MCP-compatible AI assistant over HTTP.
- Ships 71 MCP tools and 22 event callbacks covering the full debugging workflow.
- Built in Zig as a single binary with zero runtime dependencies, cross-compiled for x32 and x64.
- Supports both Streamable HTTP and SSE transports under the MCP 2024-11-05 JSON-RPC 2.0 spec.
- Bearer token auth included, but traffic is unencrypted HTTP and should stay off untrusted networks.
- MIT licensed, roughly 1,300 GitHub stars, aimed at malware analysis and reverse engineering workflows.
Reverse engineering has long been a manual grind: set a breakpoint, step through, dump memory, scribble notes, repeat. A new open-source project called x64dbg-MCP Server tries to short-circuit that loop by wiring the popular Windows debugger directly into any MCP-compatible AI assistant, so an agent can drive the tool the same way a human would.
x64dbg-MCP Server is a native Model Context Protocol plugin for x64dbg that exposes the debugger's full functionality over HTTP. Once installed, it lets a client like Claude Code invoke debugger operations as tools: setting breakpoints, stepping, reading memory, dumping registers, and dozens more. The project is MIT-licensed and has already crossed roughly 1,300 stars on GitHub within days of release.
Zig, no runtime, drop-in install
The unusual choice here is the implementation language. Built with Zig, the plugin ships as a zero-dependency single binary and cross-compiles to both x32 and x64 from any host. No .NET, no Python, no runtime, just drop it into your x64dbg plugins folder and go. That matters because reverse engineering rigs are already fragile, and adding a Python sidecar or a background service to a malware analysis VM is exactly the kind of thing analysts avoid.
