Overview

What is Weather MCP Server?

Weather MCP Server is a Model Context Protocol (MCP) server that provides weather information using the National Weather Service (NWS) API. It is designed for developers and AI assistants who need real-time weather alerts and forecasts for US locations.

How to use Weather MCP Server?

Clone the repository, set up a Python 3.10+ virtual environment, and install required packages with uv add "mcp[cli]" httpx. Configure settings in config.py (e.g., NWS_API_BASE, USER_AGENT, LOG_LEVEL). Run standalone with python weather.py or use as a tool named "weather" within an MCP client like Cline, calling get_alerts(state) and get_forecast(latitude, longitude).
