About SHEARLINE
SHEARLINE is an MCP server in the Maps category: analyst-grade US severe weather: warnings with IBW tags, SPC outlooks, RAP environments, MRMS, LSRs.

Tools (10)
get_active_warnings(lat, lon, radius_km=40)Active tornado/severe-thunderstorm/flash-flood warning polygons with IBW tags (max hail size, max gust, tornado detection/damage threat), parsed storm motion, expirations, and whether the exact point is inside a polygon. Watches listed separately.
Parameters not published.
get_environment_trend(lat, lon)The anticipatory view: a short RAP forecast series (f00/f01/f03/f06, one consistent cycle) of MLCAPE, 0–6 km shear, 0–1 km SRH, SCP and STP, with an interpretation of the **trajectory** (intensifying / stabilizing / steady) — for "is this getting worse" rather than "what is it now."
Parameters not published.
get_historical_storm_reports(lat, lon, date, radius_km=80)What hail/wind/tornado hit a point on a specific past date (`YYYY-MM-DD`, UTC) — normalized reports with magnitude+units and distance/bearing, for the insurance / ag / forensic use case. Coverage from ~2005; preliminary LSRs, not the final NCEI record.
Parameters not published.
get_lightning(lat, lon, radius_km=40, minutes=15)GOES-East GLM total-lightning activity in the recent window: flash count and rate, nearest strike (distance/bearing/time), and a tiered outdoor-safety interpretation (overhead / within-striking-distance / in-the-area).
Parameters not published.
get_mrms_severe(lat, lon, radius_km=40)MRMS maxima within radius: 60-min MESH (hail, inches and mm), low-level and mid-level rotation tracks (azimuthal shear), VIL, composite reflectivity — each with valid time and distance/bearing of the max.
Parameters not published.
get_point_environment(lat, lon)Latest RAP 13-km analysis profile computed with MetPy: MLCAPE/MUCAPE/CINs, LCL, 0–1/0–6 km shear, 0–1/0–3 km SRH, Bunkers motion, effective inflow layer, effective SRH/shear, SCP, and significant-tornado parameter — interpreted like an analyst (pulse vs. cool-season high-shear vs. classic supercell parameter space).
Parameters not published.
get_radar_snapshot(lat, lon)Nearest WSR-88D's latest Level 2 volume metadata: VCP (scan strategy), max reflectivity with range/azimuth, coarse echo-top estimate.
Parameters not published.
get_spc_outlook(lat, lon, day=1)SPC categorical risk (TSTM→HIGH) at the point plus tornado/hail/wind probabilities and significant-severe flags, days 1–3, with interpretation calibrated to the category.
Parameters not published.
get_storm_reports(lat, lon, radius_km=80, hours=6)Normalized Local Storm Reports: type, magnitude with units, time, location, distance/bearing, remarks.
Parameters not published.
get_threat_brief(lat, lon)The showpiece: runs everything above concurrently and synthesizes a threat level (none/marginal/elevated/significant/extreme) **with stated logic**, hazards ranked, environment summary, nearest storm signature, and a recommended attention window.
Parameters not published.
