gdbmcp

GDB MCP server.

Overview

gdbmcp exposes GDB operations over the MCP (Model Context Protocol) using FastMCP. It manages GDB sessions over a socket connection (via gdbrpc) and provides MCP tools to connect, list, terminate sessions, and run GDB commands.

Related MCP server: dap-mcp

Features

  • Start and manage multiple GDB sessions

  • Execute arbitrary GDB commands through MCP

  • Run as MCP stdio server or HTTP server

Requirements

  • Python >= 3.10

  • gdbrpc

  • mcp

  • HTTP mode only: uvicorn (required to run the HTTP server)

Installation

From PyPI:

pip install gdbmcp-server

From repo root:

pip install .

For development:

pip install -e .

Usage

Run MCP server (stdio)

python -m gdbmcp-server gdbmcp --stdio

Run MCP server (HTTP)

python -m gdbmcp-server

MCP Tools

gdb_connect(host: Optional[str] = None, port: Optional[int] = None) -> str

Establish a GDB session and returns a session ID.

gdb_terminate(session_id: str) -> str

Terminate an existing session and clean up resources.

gdb_list_sessions() -> str

List all active sessions and their host/port.

gdb_command(session_id: str, command: str) -> str

Execute a GDB command in the session and return output.

Configuration

CLI flags:

  • --stdio : Run in stdio transport mode

  • --port : HTTP server port (default: 20819)

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
