GDB MCP Server

A Model Context Protocol (MCP) server that enables LLM clients to interact with GDB for debugging and binary analysis.

Quick Start

uv sync
uv venv
uv run server.py

Integration

Note that you can use uv run to run the server.py script or you can use uv venv to create a virtual environment and then run /home/youruser/dev/personal/GDB-MCP/.venv/bin/python /home/youruser/dev/personal/GDB-MCP/server.py.
