GNURadio MCP Server

GNURadio MCP Server is a modern, extensible Machine Control Protocol (MCP) server for GNURadio, enabling programmatic, automated, and AI-driven creation of GNURadio flowgraphs. Designed for seamless integration with Large Language Models (LLMs), automation frameworks, and custom clients, it empowers you to generate .grc files and control SDR workflows at scale.

Why GNURadio MCP Server?

• Automate SDR workflows and flowgraph generation
• Integrate with LLMs, bots, and custom tools
• Build, modify, and validate flowgraphs programmatically
• Save time and reduce manual errors in SDR prototyping

Features

• 🌐 MCP API: Exposes a robust MCP interface for GNURadio
• 🛠️ Programmatic Flowgraph Creation: Build, edit, and save .grc files from code or automation
• 🤖 LLM & Automation Ready: Designed for AI and automation integration
• 🧩 Extensible: Modular architecture for easy extension and customization
• 📝 Example Flowgraphs: Includes ready-to-use .grc examples in the misc/ directory
• 🧪 Tested: Comprehensive unit tests with pytest

Quickstart

Requirements

• Python >= 3.13
• GNURadio (Tested with GNURadio Companion v3.10.12.0)
• UV

Usage

1. Clone the repository

2. Install GNURadio
3. Set up a UV environment

The --system-site-packages flag is required because GNURadio installs the gnuradio Python package globally.

4. Add the MCP server configuration to your client configuration. For example, for Claude Desktop or Cursor:
