The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_lightning_activity unknown never probed

    Real-time lightning near a location: GLM satellite flash count (30km/10min) and MRMS ground-truth lightning density + 30-minute probability. The summary field is ready-to-use. A zero flash count means no lightning inside that window -- report it as a quiet observation scoped to the window in `scope`, never as a data gap. Only call when storms may be active or the user asks about lightning. Example: {"location": "Tampa"}.

  • search_locations unknown never probed

    Resolve a place query to candidate locations with coordinates. Accepts city names ("Denver"), city+state ("Portland, OR" via query), ZIP codes ("50219"), or partial input with fuzzy=true for autosuggest-style matching ("bost" -> Boston). Returns ranked candidates with lat/lon. Most weather tools accept a `location` string directly and geocode internally -- use this tool only to disambiguate ("which Springfield?") or to present location choices to the user. Example: {"query": "Springfield"} returns all major Springfields ranked by place importance.

  • query_dataset unknown never probed

    Raw time series from a specific dataset for specific variables at a point. Power-user access to any gridded product (NBM, HRRR, RRFS, GFS, RTMA, MRMS, air quality, ...). Time modes: hours (next N hours, default 24), time_start+time_end (explicit ISO-8601 window), or latest=true (single most-recent value). reference_time pins a specific model run, and each returned series reports the run that served it (reference_time, or reference_times when a series mixes runs) — check it before comparing two runs, since a run older than about 48 hours may no longer be available. For blended forecasts use get_forecast instead. Examples: {"location": "Denver", "dataset_id": "rrfs_surface", "variables": ["temperature_2m"], "hours": 18} or {"lat": 41.4, "lon": -92.9, "dataset_id": "rtma_conus", "variables": ["temperature_2m"], "latest": true}.

  • get_growing_degree_days unknown never probed

    Growing Degree Units (GDU / GDD) for a US location (CONUS, Alaska, Hawaii), computed from daily max/min temperatures. Pass a crop id (e.g. "corn", "soybean", "wheat") to use calibrated base/upper thresholds, or crop="custom" with base_temp_c (and optional upper_temp_c / method). Without season_start you get per-day GDU across the forecast horizon; WITH season_start (YYYY-MM-DD) you get the cumulative season-to-date total (observed history + today + forecast) plus a per-day cumulative series -- the number a grower tracks against crop milestones. Answers "how many growing degree days has my corn accumulated since May 1?" and "what's the GDU forecast this week?".

  • get_hourly_forecast unknown never probed

    Blended hourly forecast: temperature, feels-like, humidity, wind, precipitation probability/amount, conditions, and icon per hour. Snapped to the current hour so hourly[0] is "now". Timestamps are UTC ISO 8601; convert to the local timezone before presenting. Ask for the days you need up front -- one call with days: 4 beats four calls. ALWAYS check hourly_coverage before answering about a specific hour: it reports first_time and last_time (the window the rows actually span), sample_interval_hours (past the first day rows are every 2-3h, not every hour), and truncated: true when upstream returned less than you asked for. If the hour the user cares about is after last_time, say the forecast does not reach that far yet rather than answering from the nearest row you do have. For one stretch of time ask for that stretch with hours_from/hours_to: it comes back hour by hour even where the full range would be sampled. Accepts a place name or coordinates. Examples: {"location": "Portland, OR", "days": 2} or {"lat": 41.88, "lon": -87.63, "hours_from": 36, "hours_to": 48}.

  • get_forecast_skill_map unknown never probed

    Measured forecast skill as a map of res-4 hexes inside a bounding box, sliced from the public skill map. Use this when the question is spatial ("where is NBM temperature skill weak across Colorado"), not "how good is the forecast at this point" — that is get_forecast_skill. Requires model, variable, lead_hours, and bbox {west,south,east,north}. lead_hours selects the containing published bucket (20 → NBM 24); a lead we have not published returns no slices rather than a nearby one. A hex is included when its center is inside the box; edge-overlapping hexes are dropped. The box cannot wrap the dateline. Each cell is [h3, samples, skill_score]; skill_score is unitless (fraction of climatological variance explained) and already gated at n ≥ 30. withheld lists hexes still accumulating. Do not compare slices across models or truths. This is CELL# only — never treat a hex as a person.

  • get_alerts unknown never probed

    NWS watches, warnings, advisories. Point (city/ZIP/lat+lon): containing polygons. BBox or US state/DC/CONUS (codes, full names, US/national): intersecting polygons. A city miss is not a statewide all-clear — query the state or a bbox; never say regional inventory is impossible. NY/WA and "New York State"/"Washington State" are states; "New York"/"Washington" stay cities. Omit at for now; at (ISO-8601 UTC) is the snapshot then. Empty = all-clear or purged (~24h). alert_id = detail+geometry, ignores at. Ex: {"location":"WI","events":["Tornado Warning"]}.

  • get_time_context unknown never probed

    Complete temporal context for a location: local time, timezone, 14-day calendar with day names and Today/Tomorrow offsets, sunrise/sunset/solar times (from the weather pipeline's astro product), and moon phase. Use whenever you need to reason about dates, times, or daylight for a location -- including "what time is sunset?", "is it dark there now?", or "what day of the week is the 4th-day forecast?". Accepts a place name directly. Example: {"location": "Seattle"}.

  • get_forecast_distribution unknown never probed

    Probabilistic forecast guidance from NBM for one aspect of the weather: percentile ranges (p10-p90), exceedance probabilities, and ensemble spread. Use this for any question about odds, ranges, potential or confidence ("how much could we get", "worst case for the wind", "how sure is this") -- a deterministic forecast value cannot answer one. Reading the percentiles: p50 is the most likely outcome, p90 is the reasonable worst case when the risk is the high end (snow totals, wind, rainfall), and p10 is the reasonable worst case when the risk is the low end (cold, minimum visibility, ceiling). A single percentile is not the forecast -- report the likely value with the tail that matters, and label which is which. Aspects: precip (PoP, QPF + percentiles), snow (accumulation percentiles, >1/2/4in probabilities, snow level), ice (freezing rain, accretion), temperature (temp/dewpoint + stddev), wind (speed/gust percentiles), severe (hail/tornado/damaging-wind probabilities), aviation (LIFR/IFR/MVFR visibility + ceiling probabilities), confidence (ensemble stddev; low spread = settled forecast, high spread = details still in play). Examples: {"location": "Denver", "aspect": "snow", "hours": 72} or {"lat": 32.9, "lon": -97.0, "aspect": "severe"}.

  • get_climate_normals unknown never probed

    Day-of-year climate normals (NCEI 1991-2020 30-year averages) for a US location, from the nearest station with a record. Returns normal high, normal low, and normal mean for each date in the window, plus the station and how far away it is. Use this whenever a question needs a baseline rather than a forecast: "is this warm for October?", "what is a typical high here in January?", "how does this week compare to normal?". Pair it with get_forecast to say how far above or below normal the coming days run. Covers dates by day of year, so it answers for any date, past or future -- these are long-period averages, not a forecast and not observed history for a specific year.

  • get_forecast_skill unknown never probed

    How accurate our forecasts have actually been near a location, measured against observed analysis truth. Returns bias (positive = the model runs high), mean absolute error, RMSE, and a skill score against local climatology, per model, weather variable, and forecast lead time; continuous and vector entries also carry persistenceSkillScore, skill against the analysis at forecast issue time (null means not enough persist pairs, not zero skill -- do not compare it to skillScore as if they shared a denominator), and analysisDisagreementMae, the analyses' own disagreement at that lead -- a floor on how good the forecast can look, not a skill score and not an excuse (null means the sibling row is missing or below minimumSamples); for probability forecasts, the Brier score and a reliability breakdown. Use this to qualify a forecast rather than assert it -- "NBM has been running 1.8F warm at 3-day leads near you, so treat that 72 as around 70" -- and to answer "how much should I trust this forecast", "is the model biased here", or "how accurate were you last month". Evidence is reported at three scopes side by side: the exact point (strongest, slowest to accumulate), the ~50km neighborhood, and the ~300km region. Prefer the most specific scope that has samples. Metrics below minimumSamples observations are withheld and listed under insufficientHistory with their count -- say that history is still accumulating rather than treating thin numbers as evidence. Coverage is a rolling recent window over verified US variables, not all of history. Entries are per model and their samples are not matched, so never conclude that one model beats another by comparing their numbers here. Each entry states the truth field it was measured against -- one designated analysis per variable -- so never compare numbers carrying different truth values either. Each entry also states the regime it was measured under: ALL for every observation regardless of weather, or a conditioned tier such as SEA:DJF (winter), SCN1:WINDY / SCN1:WET / SCN1:QUIET (what the forecast was showing), or JC1:NW (a circulation pattern). Pass the regime parameter to ask for a conditioned track record. It falls back, so asking for SCN1:WINDY and getting back regime ALL is a successful answer, not a missing one -- always read the regime field and qualify the claim with it, because "NBM runs warm here when it shows windy" and "NBM runs warm here" are different statements. Regimes overlap by construction across families, so entries under different regimes are alternative answers to one question and must never be compared or added; within SCN1: the labels are mutually exclusive. Entries with a categorical block answer a yes/no question instead of an error magnitude -- did it rain, at the thresholdMm stated on the entry -- with pod (of the times it happened, how often we called it), far (of the times we called it, how often it did not happen), and frequencyBias (above 1 = we call it too often). Use these for "will it actually rain" questions, where a small average error means nothing if the rain lands in the wrong hour. A null rate means the sample cannot answer it -- the event has not happened, or been forecast, enough times to divide by -- and must be reported as unknown, never as zero. The counts beside it are still evidence, and for a rare event they are often the whole answer: "it has only rained twice here in the record" is a useful thing to say.

  • get_tropical unknown never probed

    Active NHC (National Hurricane Center) tropical systems: forecast cones, track lines, forecast points, coastal watches/warnings, and 7-day Tropical Weather Outlook formation areas -- Atlantic + East Pacific. Each feature carries a kind (cone | track | points | watch_warning | outlook_area) plus storm name, intensity, and timing properties. include_geometry=true adds full GeoJSON geometries (large). An empty result means no active tropical activity. Aircraft reconnaissance fixes and flight-level observations are in `get_tropical_observations`. Example: {} or {"include_geometry": true}.

  • get_tropical_observations unknown never probed

    Hurricane Hunter aircraft reconnaissance for active tropical systems: vortex data message (VDM) center fixes — pressure, max flight-level wind, eye — and high-density (HDOB) flight-level observations. These are aircraft measurements, not surface weather stations (use `get_observations` for METAR). Use `get_tropical` for NHC cones, tracks, and watches; this tool is what the aircraft measured. kind=hdob returns the newest 200 records (about 1–2 h of flight; `truncated` says when more exist). Empty when no aircraft has flown in the window.

  • get_map_snapshot unknown never probed

    Render a weather map image for visual analysis. Simple form: pass `product` (a viz-catalog product_id like "mrms_qpe_01h_pass2_conus", "goes_truecolor_conus", "spc_day1_categorical", "hrrr_precip_hybrid_derived_conus" (future radar), "hrrr_subhourly_conus" (15-min Future Radar), "mrms_radar_nowcast_conus", "rtma_conus", "nbm_daily_temps", or "nexrad_l3:{SITE}:{PRODUCT}" for single-site radar, e.g. "nexrad_l3:TLX:N0B") plus a location and zoom (5=regional, 8=metro, 10=city). Composed form: pass `scene` -- a declarative scene document layering basemap + multiple weather products + active alerts + storm features + inline GeoJSON in one image (layers draw bottom-to-top, under basemap labels). Example scene: {"scene":"1.0","view":{"center":{"lat":43.8,"lon":-91.2},"zoom":8},"layers":[{"type":"weather","product":"goes_truecolor_conus"},{"type":"weather","product":"nexrad_l3:ARX:N0B"},{"type":"alerts","filter":{"events":["Tornado Warning"]},"onError":"skip"}]}. Alert filters (all optional, AND-combined): `ids` (specific alerts), `events`, `severities`, `minSeverity` (Extreme>Severe>Moderate>Minor>Unknown). Single-site radar keys: the address is `nexrad_l3:{SITE}:{KEY}` where KEY is `N{tilt}{measurement}` and tilt 0 is the 0.5 degree sweep -- N0B reflectivity (dBZ, where and how heavy), N0G base velocity (knots toward/away from the radar), N0S storm-relative velocity (storm motion removed, so a couplet is rotation rather than translation -- prefer it for rotation questions), N0C correlation coefficient (0-1, debris and hail), N0X differential reflectivity (dB). Legacy codes (N0V, N0R, N0Q) are accepted as aliases. Not every site produces every key; when a render reports which keys a site has, retry with one of those. Optional `time` (unix seconds): closest frame. Forecast (HRRR/nowcast/NBM) honors future times; analysis (MRMS/NEXRAD/RTMA/GOES) clamps to latest past. Pass `time` for future-radar asks — do not claim that capability is missing. Product ids must be real viz-catalog entries -- shorthand like "radar" or "reflectivity" is not one. Omit `product` for the default hybrid precip still. For Alaska and Hawaii prefer a local site or `mrms_precip_hybrid_derived_alaska` over CONUS mosaics, which do not cover them. Returns the rendered image plus per-layer resolved valid times.

If a source is degraded or in outage, tell the user their data may be stale rather than presenting it as live. No inputs. Refreshed about every 5 minutes.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/3a1559994cb77ccc/badge.svg)](https://brick.blue/agent/3a1559994cb77ccc)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
