Implementation Reference

src/apis/weather/openweather.ts:102-107 (handler)

The main handler function for the 'get_weather_alerts' tool. It checks for API key configuration, extracts and validates the location parameter, and delegates to the OpenWeatherClient's alertsByLocation method.

async get_weather_alerts(args: Record<string, unknown>) {
  if (!cfg.openWeatherApiKey) throw new Error("OPENWEATHER_API_KEY is not configured");
  const location = String(args.location || "");
  if (!location) throw new Error("location is required");
  return client.alertsByLocation(location);
},

src/apis/weather/openweather.ts:75-81 (schema)
Input schema definition for the 'get_weather_alerts' tool, specifying that a 'location' string is required.
```
inputSchema: {
  type: "object",
  properties: {
    location: { type: "string" },
  },
  required: ["location"],
},
```

src/apis/weather/openweather.ts:72-82 (registration)

Tool registration entry in the OpenWeather module's tools array, defining name, description, and schema.

{
  name: "get_weather_alerts",
  description: "Get weather alerts for a location (requires One Call support)",
  inputSchema: {
    type: "object",
    properties: {
      location: { type: "string" },
    },
    required: ["location"],
  },
},

src/tools/register.ts:22-33 (registration)

Global tool registration in registerAllTools, which includes registerOpenWeather() thereby registering the 'get_weather_alerts' tool among others.

const registrations: ToolRegistration[] = [
  registerOpenWeather(),
  registerGoogleMaps(),
  registerNewsApi(),
  registerGitHub(),
  registerNotion(),
  registerTrello(),
  registerSpotify(),
  registerTwilio(),
  registerUnsplash(),
  registerCoinGecko(),
];

src/apis/weather/openweather.ts:30-40 (helper)

Helper method in OpenWeatherClient that geocodes the location, fetches One Call API data, and extracts weather alerts.

async alertsByLocation(location: string) {
  const geo = await this.geocodeCity(location);
  const first = Array.isArray(geo) && geo.length > 0 ? geo[0] : undefined;
  if (!first) return { alerts: [] };
  const { lat, lon } = first as { lat: number; lon: number };
  // One Call 3.0 - alerts field appears if available in your plan
  const data = await this.request("/data/3.0/onecall", {
    query: { lat, lon, appid: this.apiKey, units: "metric" },
  });
  return (data as any).alerts || [];
}
