x64dbg-MCP Server is a native Model Context Protocol plugin that lets AI assistants control x64dbg through HTTP. It exposes debugger operations for loading programs, stepping execution, setting breakpoints, reading memory, inspecting registers, and analyzing modules. The toolset also covers threads, call stacks, symbols, references, pattern scans, PE structures, dumps, tracing, and process internals. Event callbacks let clients react to debugger state changes such as exceptions, pauses, DLL loads, and breakpoints. It supports both Streamable HTTP and SSE transports with JSON-RPC 2.0. Mandatory bearer authentication protects every request, and configuration changes can restart the server automatically. Written in Zig, it has no runtime dependencies and can build x32 and x64 plugins from one codebase.
