x64dbg-MCP Server is a native [MCP](https://modelcontextprotocol.io/) (Model Context Protocol) plugin for [x64dbg](https://x64dbg.com/) that exposes the debugger's full functionality over HTTP. Connect any MCP-compatible AI assistant and control x64dbg programmatically: set breakpoints, step through code, read memory, dump registers, and more.

Built with [Zig](https://ziglang.org/) — zero dependencies, single-binary output, cross-compiles to both x32 and x64 from any host. No .NET, no Python, no runtime — just drop the plugin into your x64dbg plugins folder and go.

> **MCP 2024-11-05** — Streamable HTTP + SSE transports, JSON-RPC 2.0.


## Features

- **84 MCP Tools:** Full debugger control — disassembly, stepping, breakpoints, memory allocation, registers, modules, threads, call stack, pattern scanning, string extraction, xrefs, symbols, bookmarks, PE analysis, OEP detection, module dumping, PEB/SEH inspection, tracing, and more.
- **22 Event Callbacks:** Full debugger event coverage — init, stop, breakpoint, exception, step, attach/detach, DLL load/unload, threads, and more.
- **Zero Dependencies:** Pure native plugin, no runtime or framework needed.
- **x32 and x64:** Single codebase, builds both architectures from one command.
- **Dual Transport:** Streamable HTTP + SSE — compatible with any MCP client (new and legacy).
- **Bearer Auth:** Mandatory token authentication — auto-generated on first run, required on every req
