MCP Weather Server

Example Use Cases

• 1

  Fetch current and forecast weather data for a specified latitude and longitude within the United States.

• 2

  A lightweight, self-hosted MCP endpoint to prototype integrations with the National Weather Service API.

• 3

  An example Node.js MCP implementation to learn how to expose external APIs to agent workflows (including build and cursor configuration).

Description

This repository provides a quickstart implementation of an MCP server that uses the US National Weather Service (NWS) API to return weather forecasts for a given latitude and longitude. It is intended as a learning/example project (based on a Zenn article) and includes build and run instructions for a Node.js-based server. The server only supports locations within the United States and is easy to integrate into agent workflows via a simple cursor configuration.
