The Weather Forecast service acts as an MCP server, enabling AI assistants like GitHub Copilot to access up-to-the-minute weather information. It extends AI capabilities beyond their training data by connecting to external data sources. Built with FastMCP and FastAPI, it provides a robust, stateless interface for querying hourly forecasts for any given location, backed by the Open-Meteo API and secured with Authentik authentication. Additionally, it exposes a traditional REST API for standard application integration, offering a flexible solution for various development needs.
