Accepts a `url` (existing EPW), `urls` (compare 2+), or `config` (synthesize on the fly with morphing/UHI/events/smoke). Config mode runs the full generation pipeline server-side but returns only stats — never the EPW content. **Token-saver: pass `compact: true` to get a ~10-field headline response (~100 tokens) instead of the full ~800-token payload.** Use compact for sanity-checking, dashboards, or when chaining many calls; full when you need monthly arrays / peak days / full ASHRAE. Optional `include_full_ashrae` adds ASHRAE 0.4/1/2% cooling + 99.6/99% heating design conditions with mean coincident dewpoint. Optional `include_improbability` (config mode) adds a stress-test score. Optional `include_idf` adds ready-to-paste EnergyPlus SizingPeriod:DesignDay objects. Optional `units` ('imperial' default | 'metric'). **Presentation: when calling with `urls` (multiple files), the response includes a `comparisons` array — render it as a markdown table to the user. Lead with the headline delta, not the raw data.** No auth required; no credits charged.

Eight chart types: `diurnal` (~10 KB, monthly hourly profile), `temp_carpet` (heatmap of hour × day-of-year — ~30 KB preview / ~150 KB full), `wind_rose` (~12 KB, polar bars by direction × speed), `monthly_boxplot` (~6 KB, Q1/median/Q3 + whiskers per month), `utci_carpet` (~90 KB, outdoor heat-stress hour × day, colored by UTCI category — Bröde 2012, shaded Tmrt), `economizer_carpet` (~90 KB, air-side economizer free / integrated / locked-out hour × day under ASHRAE 90.1 high-limit), `pv_tilt_azimuth` (~60 KB, annual PV generation across full tilt × azimuth space, isotropic-sky POA at lat from EPW header — optimum orientation marked), `solar_under_events` (~12 KB, weekly GHI of the modified scenario vs the no-overlay reference; bands color event-affected weeks. Requires `config` — server runs the pipeline twice, with and without overlays), `comparison` (~10 KB, design-condition deltas across EPWs). Accepts `url` (single), `urls` (2+ for comparison), or `config` (synthesize on the fly). Config mode is anon-safe — runs pipeline, returns SVG only. No auth required. **Token budget**: SVGs are returned inline by default. Large outputs (>50 KB) auto-upload to Blob storage (when configured) and return a URL instead, keeping your context lean. Always check `svg_size_kb` in the response. **Presentation: when handing the chart to the user, just link or embed it — don't narrate what's in it. Let the chart speak.**

In MCP Apps-capable hosts (Claude Desktop, ChatGPT, VS Code, Goose), the response renders as a widget with sliders for SSP / year / percentile / UHI — dragging a slider re-calls this tool live. Use when a user wants to interactively tune a single site. For multi-site comparison, use analyze_weather(urls=[...]) instead. Defaults to present-day TMY (no morph) — pass ssp+year for future scenarios. P75 default percentile is design-realistic; P50 underestimates the tail. No auth required.

Returns matching stations with EPW URLs ready to pass to analyze_weather or chart_weather. Optionally enriches with AMY extreme years (hottest / coldest / most-humid on record) and CMIP6 climate deltas. No auth required.

A paid tool — charges credits per call: 1 for a single file, 1 per scenario for a scenarios batch (max 10), 10 for a per-model CMIP6 ensemble. Requires auth (Bearer API key or OAuth). Credits come from a Forge pass ($9.99/wk = 2 non-expiring credits, or $99/yr) or a top-up pack; see the epwforge://catalog/pricing resource. No account? Buy a fixed-price guest bundle — see preview_forge_bundle. For free analysis without credits, use analyze_weather or chart_weather on a real published EPW URL.
