Nws Weather Mcp Server

The Nws Weather Mcp Server is an open-source MCP (Model Context Protocol) server that exposes real-time US weather data from the National Weather Service API for AI assistants and MCP-compatible clients. It offers tools to retrieve 7-day or hourly localized forecasts, active weather alerts (with flexible filtering), current observations, nearby station discovery, and a resource listing all possible weather alert event types. It requires no authentication and is designed for seamless integration with AI workflow platforms and virtual agents in need of reliable, live US weather data. The server can be used both as a public API endpoint or via local/self-hosted deployment.
