noaa_get_sea_level_trendsGet the long-term relative sea level trend at a NOAA station: trend and error (reported by NOAA in mm/yr or inches/decade — the payload's trendUnits field says which), the observation period (startDate/endDate), and seasonal amplitude. Relative sea level combines ocean rise AND local land movement …
noaa_get_sea_level_rise_projectionsGet NOAA's Interagency Sea Level Rise Scenario projections for a station (from the 2022 technical report): projected relative sea level (meters or feet, see units field) per decade through 2150 under the chosen scenario. Scenarios: low, intermediate-low, intermediate, intermediate-high, high, extre…
noaa_get_extreme_water_levelsGet NOAA's extreme water level exceedance statistics for a station: the annual exceedance probability levels (e.g. the 1%-annual-chance "100-year" level) and historical extreme events, computed from the station's verified record. Use for flood risk questions ("what water level has a 1% chance per y…
noaa_get_top_ten_water_levelsGet a station's highest recorded water levels: analysis "toptenwaterlevels" returns the ten highest events on record (with date, height, causal event name like "Great New England Hurricane", and category); "peakwaterlevels" returns peak event records (optionally filtered by year). Heights are relat…
noaa_get_high_tide_floodingGet NOAA high tide flooding (HTF, "nuisance"/"sunny day" flooding) statistics for a station. Reports: - daily: flood occurrence per day (REQUIRES start_date and end_date, YYYYMMDD) - monthly / seasonal / annual: counts of minor/moderate/major flood days per period (filter with year/month/season_mon…
nws_get_wind_forecastGet the NWS hourly wind FORECAST (speed, gust, direction — plus wave height where the grid carries it) for a latitude/longitude. Data comes from the NWS forecast grid (api.weather.gov gridpoints — numeric NDFD values, not display strings). Horizon is up to ~7 days (156 hours), starting at the curre…
nws_get_marine_forecastGet the official NWS Coastal Waters Forecast (CWF) narrative for the marine zone covering a latitude/longitude — day-part wind/seas text ("SE winds 10 to 15 kt... Bay waters choppy"), including Small Craft Advisories. The point must lie in (or very near) US coastal waters; CWF zones extend roughly …
noaa_get_meteorological_dataGet observed meteorological/oceanographic sensor data from a NOAA station. Products: air_temperature, water_temperature, wind (speed/gust/direction), air_pressure, air_gap (bridge clearance to water surface), conductivity, visibility, humidity, salinity. Units by system: temps °F/°C; wind knots (e…
noaa_get_reference_guidenoaa_get_station_datumsGet the accepted tidal datum values for a station: the elevations of MHHW, MHW, MTL, MSL, DTL, MLW, MLLW, STND, NAVD88 (where computed), plus GT (great diurnal range), MN (mean range), LAT/HAT (lowest/highest astronomical tide), and the station's historical extreme min/max water levels with dates. …
noaa_get_harmonic_constituentsGet the harmonic constituents NOAA uses to compute tide or current predictions at a station — the amplitude, phase, and angular speed of each tidal constituent (M2, S2, N2, K1, O1, ...). For water-level stations: amplitude (feet/meters), phase_GMT and phase_local (degrees), speed (degrees/hour). Fo…
noaa_get_prediction_offsetsGet the offsets a subordinate (type "S") prediction station applies to its reference station's predictions. kind "tide": returns refStationId, time offsets for high/low tide (minutes), height offsets for high/low tide, and whether the height adjustment is a ratio (multiplied) or fixed value — this …
noaa_search_stationsSearch the NOAA CO-OPS station directory by capability type, name, and/or state. Filter with: - type: what the station does (waterlevels, tidepredictions, currents, currentpredictions, met, ...) — pick the type matching the data you plan to request. - name: case-insensitive substring ("San Francisc…
noaa_find_nearest_stationsFind the NOAA stations closest to a latitude/longitude point, sorted by distance.

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
25/25 tools missing one or more hints — astro_get_moon_phase (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); astro_get_next_moon_phase (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); astro_get_sun_times (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
Only 0/25 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 12 high severity in production deps — axios@1.10.0 (high), axios@1.10.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
