What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• find_places

  Find places: a name, ZIP, venue or address to ranked candidates with lat/lon, or coordinates to the place and timezone. Pass `query` or `lat`+`lon`; rows carry `type` place|zip|address|poi|county|station, `matched_via: "autosuggest"` marks fallback rows and `partial` a timed-out

• get_forecast

  Forecast for one US place: current conditions, daily forecast with sunrise and sunset, active alerts and outlooks in one call, hour by hour with include=hourly, and air quality (AQI) with include=aqi; several places: get_data with `locations`. Blended across NBM, HRRR, GFS, RTMA

• get_current_conditions

  Current weather right now at a place: the observed analysis at the exact point (temperature, dew point, relative humidity derived from them, wind speed, direction and gusts, pressure, visibility, cloud cover) plus the nearest station report. Values are in `units` (imperial by def

• get_alerts

  NWS watches, warnings and advisories in effect at a place (`location`), over a `bbox`, or over a state or county as `area` {product, feature_id} (find_places `boundaries` hands those back), now or at a past instant (`at`). Narrow with `filter` over event, severity, urgency or cer

• get_observed_precipitation

  How much rain fell: observed precipitation totals at a place over trailing 1 to 72 h windows (`hours`, default 24), or ending at a past time (`end` with `start`), from radar estimates bias-corrected to rain gauges. Values have about 0.08 in (2 mm) resolution, so 0 means under abo

• get_forecast_distribution

  Probabilistic forecast guidance for one aspect, from severe risk to aviation ceilings: percentiles (p10 to p90), exceedance probabilities and ensemble spread, for the odds, ranges or confidence one forecast value cannot answer. Read p50 as the likely outcome, p90 as the reasonabl

• search_data

  Search the data catalog: which dataset's values answer a question about weather and the people and places it affects, or what data exists at a point. With `query` it ranks datasets and map layers and returns hits with the exact `call` to run next (render (visual) for a map layer;

• find_tools

  Lists the weather tools this connection does not show (best times, routes; storm cells, storm reports, lightning; outlooks, forecaster text; forecast accuracy; maps and charts), with when to use each and its required arguments. Run one with call_tool, in this session, no reconnec

• call_tool

  Runs a tool find_tools lists, by name: same price, limits and result as calling it directly. Tools already in your list are called directly, not through this. `arguments` follows that tool's input schema.

• describe_data

  A dataset's variables or properties (standard names, units, categories, bands, aggregates), horizon, step, cadence, freshness, cost class, verified `examples` and an example_query to read its values; a map layer's axes (source, region, product facts) and render (visual) call. Fre

• get_data

  Values, totals, comparisons, people/POI counts, station observations, upper-air profiles, climate records, normals, degree days, teleconnection indices and forecaster text from any catalog dataset (models, radar, alerts, outlooks, tropical cyclones, aircraft recon, reference laye

• get_status

  Data freshness of the weather platform (no inputs needed; refreshed about every 5 minutes): overall state, per-source states (ok / degraded / outage / no_signal), open incidents with their cause (provider outage vs internal processing delay) and active provider advisories. Use it

• get_time_context

  Local time, timezone, a 14-day calendar with day names and Today/Tomorrow labels, sunrise, sunset and solar times, and moon phase and rise and set for a place. Use it to reason about dates, times or daylight there ("when is sunset?", "is it dark there now?"); when current_time.ti
