OERadio MCP Server

🎙️ Part of the oeradio.at open source ham radio tool collection. Browse all tools → oeradio.at/werkzeuge

Public MCP (Model Context Protocol) server providing amateur radio tools and calculations for IARU Region 1 operators.

Endpoint: https://oeradio-mcp.oeradio.at/mcp Author: OE8YML License: MIT

What is MCP?

Model Context Protocol (MCP) is an open standard that allows AI assistants to use external tools. Originally developed by Anthropic, MCP is now supported by Claude, ChatGPT, and Gemini. With this server, you can ask your AI assistant questions like "What are the band limits for 20m?" or "How long should my dipol be for 14.2 MHz?" and get instant calculations.
