dk_current_weather

Retrieve current weather conditions for locations in Denmark using DMI HARMONIE high-resolution model. Accepts city names, coordinates, or postal codes.

Instructions

Implementation Reference

src/servers/danish-weather.js:123-148 (handler)

The handler function that executes the dk_current_weather tool logic using Open-Meteo data.

async ({ location }) => {
  try {
    const loc = await getLocation(location);
    const data = await openMeteoFetch({
      latitude: loc.lat,
      longitude: loc.lon,
      current: "temperature_2m,relative_humidity_2m,apparent_temperature,precipitation,weather_code,wind_speed_10m,wind_direction_10m,wind_gusts_10m,surface_pressure,cloud_cover",
    });
    const c = data.current;
    const weather = WMO_CODES[c.weather_code] || `Code ${c.weather_code}`;
    const lines = [
      `## ${loc.name} — Current Weather`,
      `**Conditions:** ${weather}`,
      `**Temperature:** ${c.temperature_2m}°C (feels like ${c.apparent_temperature}°C)`,
      `**Humidity:** ${c.relative_humidity_2m}%`,
      `**Wind:** ${c.wind_speed_10m} km/h from ${c.wind_direction_10m}° (gusts ${c.wind_gusts_10m} km/h)`,
