What is Weather MCP Server?

Weather MCP Server is a Model Context Protocol server that provides weather information services using the National Weather Service (NWS) API. It exposes weather alerts and forecasts as tools for MCP clients like Claude Desktop, and also includes system tools for running shell commands and viewing processes. It is built with Python and designed for developers integrating weather data into MCP-compatible applications.
