Weather Data MCP Server

Check the operational status of the NOAA and Open-Meteo weather APIs. Use this when experiencing errors or to proactively verify service availability before making weather data requests. Returns current status, helpful messages, and links to official status pages.

Get active weather alerts, watches, warnings, and advisories for a location (US only). Use this for safety-critical weather information when asked about "any alerts?", "weather warnings?", "is it safe?", "dangerous weather?", or "weather watches?". Returns severity, urgency, certainty, effective/expiration times, and affected areas. Provide the location as coordinates (latitude+longitude), a saved location_name, or a free-text city_name. For forecast data, use get_forecast instead. If this tool returns an error, check the error message for status page links and consider using check_service_status to verify API availability.

Get the most recent weather observation for a location (global coverage). Use this for current weather or when asking about "today's weather", "right now", or recent conditions without a specific historical date range. Returns NOAA station observations for US locations and Open-Meteo model data for international locations. Optionally includes fire weather indices (Haines Index, Grassland Fire Danger, Red Flag Threat) when requested. Provide the location as coordinates (latitude+longitude), a saved location_name, or a free-text city_name. For specific past dates or date ranges, use get_historical_weather instead. If this tool returns an error, check the error message for status page links and consider using check_service_status to verify API availability.

Get future weather forecast for a location (global coverage). Use this for upcoming weather predictions (e.g., "tomorrow", "this week", "next 7 days", "hourly forecast"). Returns forecast data including temperature, precipitation, wind, conditions, and sunrise/sunset times. Supports both daily and hourly granularity. Automatically selects best data source: NOAA for US locations (more detailed), Open-Meteo for international locations. For current weather, use get_current_conditions. For past weather, use get_historical_weather. Provide the location in ONE of three ways: coordinates (latitude+longitude), a saved location name (location_name="home"), or a free-text city name (city_name="Paris, France") which is geocoded automatically. If this tool returns an error, check the error message for status page links and consider using check_service_status to verify API availability.

Get a combined weather overview for a location in a SINGLE call. Best for broad questions like "What's the weather like in Seattle?", "Is it safe to hike today?", or "Give me a weather rundown". Aggregates current conditions, forecast, and active alerts by default, and can also include air quality and lightning. Provide the location as coordinates (latitude+longitude), a saved location_name, or a free-text city_name. For a single specific data product (just the forecast, just alerts, etc.), call that specialized tool directly. Sections that are unavailable for a location (e.g. US-only alerts abroad) are noted rather than failing the whole summary.

Search for locations by name to get coordinates for weather queries. Uses Nominatim (OpenStreetMap) for excellent coverage of cities, towns, villages, and hamlets worldwide. Use this when the user provides a location name instead of coordinates (e.g., "Paris", "New York", "Tokyo", "San Francisco, CA", "Small Village, County"). Returns location matches with coordinates, timezone, elevation, and other metadata. Enables natural language location queries like "What's the weather in Paris?" by converting location names to coordinates.
