AccuWeather MCP Tools for LlamaIndex (10)
These 10 tools become available when you connect AccuWeather to LlamaIndex via MCP:
get_current_conditions
Returns temperature (metric), weather text (e.g. "Partly sunny"), RealFeel temperature, humidity, wind speed and direction, UV index, visibility, cloud cover, and precipitation. Essential for instant weather checks. Use get_location_by_key first to find the correct location key. Get current weather conditions for a location
get_current_conditions_metric
Returns temperature in Celsius, wind in km/h, visibility in kilometers. Includes RealFeel temperature, humidity, UV index, wind gusts, and precipitation data. Use for international audiences or scientific analysis. Get current weather conditions with detailed metric values
get_daily_forecast
Each day includes high and low temperatures, weather conditions, precipitation probability, wind speed, UV index, sunrise/sunset times, and air quality information. Returns data in metric units (Celsius, km/h). Essential for trip planning, event scheduling, and agricultural decisions. Use 5 days for standard weekly forecasts. Get daily weather forecast for a location
get_extended_forecast
While forecasts beyond 7-10 days have lower accuracy, this is useful for event planning, travel preparation, and agricultural scheduling. Each day includes high/low temperatures, precipitation probability, and general conditions. Use for planning events 2 weeks in advance. Get 15-day extended weather forecast
get_hourly_forecast
Each hour includes temperature, weather icon, precipitation probability, wind speed and direction, and cloud cover. Essential for detailed planning — knowing exactly when rain will start, when temperatures peak, or when conditions are safe for outdoor activities. Returns data in metric units. Use 24 hours for tomorrow planning. Get hourly weather forecast for a location
get_index_groups
This helps you understand what types of indices are available (outdoor activities, health, home & garden, etc.) before querying specific indices for a location. Use this to discover what activity planning indices are supported. Get available index groups and categories
get_location_by_key
Returns the city name, country, region, timezone, coordinates, elevation, and administrative area. Use this to verify you have the correct location before making weather queries. Get detailed information about a location by its AccuWeather key
get_weather_alarms
Includes severe weather alerts such as hurricanes, tornadoes, flood warnings, heat advisories, and winter storm warnings. Each alarm includes severity level, description, start and end times, and source. Essential for safety planning, emergency preparedness, and travel decisions. Returns empty if no active alarms. Get active weather alarms and warnings for a location
get_weather_indices
Includes indices for outdoor activity suitability, flight delay probability, UV exposure, running, hiking, golf, fishing, lawn mowing, composting, and more. Each index includes a numeric value, category (e.g. "Excellent", "Poor", "Good"), and descriptive text. Essential for activity planning, health advisories, and lifestyle decisions. Get weather indices (outdoor activity, flight, UV, etc.) for a location
search_location
The location key is required for other weather queries. Returns matching locations with their keys, country, region, and coordinates. Use this as the first step before any weather query. For example, search for "New York" to find the correct location key for New York City. Supports partial matching and returns multiple results. Search for a location by name to get its AccuWeather location key
