dbgeng-mcp

Links#

Overview
#

dbgeng-mcp is a Model Context Protocol (MCP) server that bridges AI assistants to the Windows Debugging Engine (dbgeng.dll). Built with Python and a native C++ extension (pybind11), it exposes debugger functionality as MCP tools so that LLM-based agents can launch, attach to, and inspect processes through natural language. The project is currently alpha software under active development and is MIT licensed.

1. Install (requires Python 3.10+ x64 and Debugging Tools for Windows):

pip install dbgeng-mcp

2. Run the MCP server:

dbgeng-mcp
