Use it from your agent

Give your agent this line. It reads SKILL.md, gets a Fous API key and connects the Fous MCP server. Its run then takes the method tidesandcurrents.noaa.gov/get_water_level with the inputs above.

Ask your agent

  • What is the current water level at the coast near Galveston, TX right now compared with the tide prediction?
  • Is the tide rising or falling at Newport Beach harbor, and what's the water temperature there?
  • I need the latest observed sea level in meters for the Santa Barbara waterfront, plus the predicted level for the same time.
  • Check the nearest NOAA tide station to Ocean City, Maryland and tell me the water level difference and direction of change.
  • Give me the observed water level in feet and water temperature for the station closest to Savannah, GA's coast.
  • Finds the nearest NOAA tide prediction station to a US coastal place (within 30 miles) and returns its high and low tide times in local time with predicted heights above MLLW.

    tidesandcurrents.noaa.gov/get_tide_times
  • Gets the 30-minute chance of aurora overhead near a place, current geomagnetic activity, and the three-day Kp outlook. Visibility also depends on darkness and local conditions; tonight uses approximate local solar hours 18:00-06:00.

    swpc.noaa.gov/get_aurora_forecast
  • Lists active tropical cyclones in the selected basin, strongest first, with current conditions, advisory and forecast cone.

    nhc.noaa.gov/list_active_storms
  • Lists NOAA space weather alerts, warnings, watches and summaries issued in the last 1 to 7 days, newest first, with validity times and NOAA scale levels when the message gives them.

    swpc.noaa.gov/list_space_weather_alerts
  • Gets the latest water height, flow, 24-hour trend and flood-stage status at the active USGS river gauge best matching a river or town and state. Flood stage is null when not published; gauges without recent stage, flow or 24-hour history are not returned.

    waterdata.usgs.gov/get_river_level
  • Gets the latest observed weather from a nearby National Weather Service station for a US city, address, or ZIP code. Measurements the station does not report are null.

    weather.gov/get_current_conditions
  • Gets current conditions and RealFeel for a city or postal code on AccuWeather. The UV level follows standard UV-index ranges. Air quality is null unless it is shown with the current conditions.

    accuweather.com/get_current_weather
  • Gets current conditions and today's high and low from The Weather Channel for a city, postcode, ZIP code or street address worldwide. Street addresses are geocoded exactly first; some observations omit gusts or other measurements.
