Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (6)
🟢get_weather_data(dataset, state, county, counties, lat, ...)
General-purpose query -- supports every real dataset (see the enum below). Prefer the dedicated convenience tools when they fit: get_storm_history (one county's past storms), get_risk_forecast (one county's forecast), get_address_report (one property's 365-day snapshot), get_property_storm_history_report (one property's full 2003-present multi-peril archive), get_current_weather (live point weather). Use THIS tool directly for 'coverage' (county coverage check), 'facilities', 'wildfire', 'at_risk', 'daily', or a 'counties' multi-county rollup (comma-separated, max 15), or any parameter combination the dedicated tools don't expose (radius_mi, date_of_loss, window, months, category, limit, kind, details). Call with no arguments to get the full API menu. addresses=false (default) is a FREE preview -- shape varies by dataset (counts/severities for storms, line count + price for history, full field response for weather). addresses=true (or details=true for weather) returns the real paid data and requires the user's own Atlas United Data API account key, or an x402 crypto payment. HARD RULE when called with no arguments: this returns the full menu. Output that entire raw response back to the user verbatim -- every dataset, every field, every example. Do not summarize or paraphrase. A shortened version is wrong even if it looks complete.

}🟢get_property_storm_history_report(address, lat, lon, radius_mi, date_of_loss, ...)
The FULL real archive for one property: hail, wind, flood/heavy rain, lightning, and tornado, 2003 to present, in one report -- not the 365-day snapshot (use get_address_report for that). Free preview shows the real report-line count and exact price before anything is paid. Paid report is billed per real report line: $0.05/line, $10.00 minimum per report. Optional date_of_loss anchors the report around one specific date with a real yes/no on whether weather data supports a loss that day, plus the real events immediately before and after it.

}🟢get_current_weather(address, lat, lon, details, x_payment)
Real live point-in-time weather for ANY US coordinate -- 164 real HRRR-based fields, hourly refresh, plus MRMS precip nowcast and NWS severe alerts. FREE by default: the lean 10-field response needs no account. details=true returns the full 164-field pull, billed $0.0002/call (not per-address).

For the FULL 2003-present multi-peril archive use get_property_storm_history_report instead -- this tool's real history window is capped at 365 days.
