Server tool list (7)
Raw names from tools/list. Only developers need these.
| nws_get_forecast | Get the weather forecast for a US location. Returns either named 12-hour periods (default) or hourly breakdowns. |
| nws_search_alerts | Search active weather alerts (watches, warnings, advisories) across the US. Filter by state, coordinates, zone, event type, severity, urgency, or certainty. area, point, and zone are mutually exclusive. Omit all filters for a national search. |
| nws_get_observations | Get current weather observations (actual measured conditions). Accepts coordinates (resolves nearest station automatically) or a station ID directly (e.g., "KSEA"). |
| nws_find_stations | Find weather observation stations near a location. Returns stations sorted by proximity with distance and bearing. Use to discover station IDs for nws_get_observations. |
| nws_list_alert_types | List all valid NWS alert event type names. Use to discover valid values for the event filter in nws_search_alerts, or to browse alert categories. No parameters required. |
| nws_get_office_discussion | Get the latest narrative forecast product from a Weather Forecast Office (WFO). The default product is AFD (Area Forecast Discussion), which explains the meteorological reasoning behind the forecast — synoptic setup, model guidance, and forecaster confidence. Other types: HWO (Hazardous Weather Outlook, 1-7 day severe/flood/winter outlook), ZFP (Zone Forecast Product, zone-by-zone text), SPS (Special Weather Statement, short-fuse advisory). The office code is the 3-letter WFO identifier returned as the "office" field by nws_get_forecast. |
| nws_get_zone_forecast | Get the text forecast for a public NWS forecast zone. Returns named forecast periods (e.g., "Today", "Tonight", "Monday") with detailed narrative text — the human-readable, zone-level forecast written by local forecasters. Completes the alert-to-forecast chain: nws_search_alerts returns zone codes in "affectedZones", and nws_find_stations returns them in the "forecastZone" column; use those codes here. Zone codes follow the pattern XXZ### (e.g., "WAZ315" for Western Washington lowlands). County zone codes (XXC###) are not supported — use the forecast zone code. |
