The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_weather ~604
Compute design conditions, HDD/CDD, monthly stats, and peak heating/cooling days for one or more EPW files. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| compact | boolean | – | Return a ~10-field headline-only response (~100 tokens) instead of the full ~800-token payload. Drops monthly arrays, peak days, n_hours, weather_basis blob. Good for sanity checks, dashboards, batch… |
| config | object | – | Synthesize an EPW server-side and analyze it. Stats only — file never returned. lat + lon required. Same morph/UHI/event params as generate_weather_file. |
| include_full_ashrae | boolean | – | Add ASHRAE 0.4%/1%/2% cooling DB + 99.6%/99% heating DB design conditions to the response. Free. Ignored when compact=true. |
| include_idf | boolean | – | Add ready-to-paste EnergyPlus SizingPeriod:DesignDay IDF objects to the response. AEC-facing. Ignored when compact=true. |
| include_improbability | boolean | – | Add EPWForge's stress-test improbability score (config mode only). Indicates how extreme the synthesized scenario is vs historical baselines. |
| units | string | – | Output units (default: imperial). When 'metric', temperatures are °C, wind m/s, precip mm, distance km/m. |
| url | string | – | EPW URL to analyze (single file) |
| urls | array | – | Multiple EPW URLs for comparison (first = baseline). Max 10. |

chart_weather ~769
Render an SVG chart from EPW data. 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.**
| Name | Type | Req | Description |
|---|---|---|---|
| chart_type | string | – | Default: diurnal |
| config | object | – | Synthesize an EPW and chart it. Same params as generate_weather_file. SVG only — no file delivery. |

| resolution | string | – | temp_carpet only. 'preview' (default) ~30 KB with 32 color buckets — visually identical at typical render sizes. 'full' ~150 KB with per-cell rgb() — use only when saving to file or when you specific… |
| url | string | – | EPW URL (single-EPW charts: diurnal, temp_carpet, wind_rose, monthly_boxplot, utci_carpet, economizer_carpet, pv_tilt_azimuth) |
| urls | array | – | EPW URLs for chart_type=comparison (first = baseline) |

explore_design_conditions ~291
Interactive single-site design-conditions explorer. Returns full ASHRAE design conditions + diurnal chart for the requested scenario. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| allow_custom_location | boolean | – | Required when no OneBuilding station within 50 km |
| lat | number | yes | Latitude, decimal degrees |
| lon | number | yes | Longitude, decimal degrees |
| percentile | integer | – | Warming percentile. P75 design-realistic; P50 median. |
| ssp | string | – | CMIP6 emission scenario. Omit for present-day TMY. ssp370 is the recommended high-end; ssp585 (SSP5-8.5) is an opt-in extreme stress-test pathway for worst-case analysis. |
