The tools

Everything this server exposes.

The exact tools your agent sees, with their real parameters and the shape of what comes back. Descriptions are written for the model, so it knows when to call each one on its own.

Convert a US street address to latitude/longitude. Use first when you have an address but need coordinates for the weather/elevation tools.

Parameters
addressstringrequired
A US street address.
geocode("1600 Pennsylvania Ave NW, Washington DC")
{
  "address": "1600 Pennsylvania Ave NW, Washington, DC",
  "lat": 38.8977,
  "lon": -77.0365
}
weather_forecastSource: NWS

A multi-day US forecast by lat/lon — named periods (Today, Tonight…) with temperature, wind and a short + detailed forecast.

Parameters
latnumberrequired
Latitude.
lonnumberrequired
Longitude.
hourlybooleanoptional
Return the hourly forecast instead of daily periods.
