# Rigctl MCP Server [](https://badge.fury.io/py/rigctl-mcp) [](https://www.python.org/downloads/) A Model Context Protocol (MCP) server for controlling Software Defined Radio (SDR) applications via the Hamlib rigctl protocol. ## Overview This MCP server provides AI assistants with the ability to control radio receivers and SDR software like SDR++, GQRX, and other Hamlib-compatible applications. It implements the rigctl network protocol, allowing frequency tuning, mode selection, and recording control. ## Features - **Frequency Control**: Set and query radio frequency in Hz - **Mode Control**: Select demodulation mode (FM, WFM, AM, USB, LSB, CW, DSB, RAW) - **Recording Control**: Start/stop audio recording - **Quick FM Tuning**: Convenience tool for tuning FM broadcast stations (88-108 MHz) - **Timed Recording**: Record audio for a specified duration with automatic start/stop ## Supported Applications Any application that supports the Hamlib rigctl network protocol: - **SDR++** - Popular cross-platform SDR application - **GQRX** - Linux SDR receiver - **CubicSDR** - Cross-platform SDR application - **rigctld** - Hamlib network daemon for hardware radios ## Installation ### Using uvx (recommended) ```bash uvx rigctl-mcp ``` ### Using pip ```bash pip install rigctl-mcp ``` ### From source (development) ```bash git clone https://github.com/Zappatta/rigctlmcp.git cd rigctlmcp pip install -e . ``` ## Setup ### SDR++ Configuration 1. Open SDR++ 2. Enable the **Rigctl Server** module in Module Manager 3. Configure rigctl settings: - **Port**: 4532 (default Hamlib port) - **Bind Address**: - `0.0.0.0` if using from Docker - `127.0.0.1` if running locally 4. Connect to your SDR device ### Docker Note If running the MCP server in Docker, the rigctl server must bind to `0.0.0.0` to be accessible from the container. Use …
