-See the [Build an MCP server](https://modelcontextprotocol.io/docs/develop/build-server) tutorial for more information.
+A minimal MCP server that exposes US weather data from the [National Weather Service API](https://www.weather.gov/documentation/services-web-api) as two tools:
+
+- `get-forecast` – get the forecast for a location (takes `latitude` and `longitude`)
+- `get-alerts` – get active weather alerts for a US state (takes a two-letter state code)
+
+This example accompanies the [Build an MCP server](https://modelcontextprotocol.io/docs/develop/build-server) tutorial.
+
+## Prerequisites
+
+- Node.js 24+
+- npm
+
+## Build and run
+
+```bash
+npm install
+npm run build
+node build/index.js
+```
+
+The server communicates over stdio, so running it directly just waits for a client on stdin. To see it in action, launch it from one of the client examples in this repository, for example:
+
+```bash
+cd ../mcp-client-typescript
+npm install && npm run build
+node build/index.js ../weather-server-typescript/build/index.js
+```
