fldigi-mcp

An MCP server for controlling fldigi, the popular amateur-radio digital-modem application, from MCP-aware clients. It connects to fldigi's built-in XML-RPC control interface and exposes the whole API as a small set of logically-grouped MCP tools, allowing an assistant to read the radio's state and drive the modem, rig, log, and transmitter through plain language.
