Data offered docs-verified: current conditions (temperature, wind, sky, dewpoint) · NWS 7-day or hourly forecast · active warnings/watches with GeoJSON polygons · raw/decoded METAR for any ICAO station · non-US locations via Open-Meteo · SPC Day 1 outlook and active watches · NWP model field imagery (22+ products, 3 models) · NEXRAD Level 2 reflectivity radar imagery · radar storm cell analysis · 205 meteorological calculations · model sounding at a point (40 levels plus derived parameters)
Coverage llm-inferred: United States (NWS, SPC, NEXRAD); non-US locations via Open-Meteo (wx_global)
Formats docs-verified: PNG · GeoJSON · MCP stdio
Access docs-verified: Open-source GitHub project (licence not stated in entry or docs). No API key or auth documented. Data tools need only Python with requests and mcp. Image and calculation tools need optional Rust-backed packages (metrust, cfrust, rusbie, rustweather). Radar rendering needs rustdar built from source.

Use cases llm-inferred: Site-visit weather log for UK or non-US sites using wx_conditions or wx_global, as an audit record of conditions · Derived atmospheric parameters (dewpoint, CAPE, LCL) via wx_calc for technical notes or drainage and flood input checks · Forecast briefing for construction or monitoring work windows using wx_brief or wx_forecast · NWP field and radar figures for client report appendices using wx_model_image or wx_radar_image
Audience llm-inferred: hydrologists · drainage engineers · environmental consultants · GIS analysts

Constraints docs-verified: Native data sources are US-focused (NWS, SPC, NEXRAD); non-US coverage relies on Open-Meteo via wx_global · No UK-specific source (e.g. Met Office) is listed · Image and calculation tools require optional Rust packages; radar needs a source build and RADAR_RENDER_PATH · Built for Claude Code; configuration is via ~/.claude/settings.json and needs a restart · Rate limits and upstream availability are not documented · Community project; maintenance commitment is not documented

Auto-extracted, unverified fields: tools, install, auth. Check upstream documentation.

Tools/install/auth auto-extracted from README; quality score heuristic (stars, recency, tool count, licence).
