EPW & DDY weather files for any location — TMY, CMIP6 SSPs, UHI, extreme events, smoke.
Epwforge MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. EPW & DDY weather files for any location — TMY, CMIP6 SSPs, UHI, extreme events, smoke.
EPWForge generates and morphs weather files (.epw, .ddy, .csv) for building energy simulation tools — EnergyPlus, OpenStudio, IES VE, eQUEST, and any workflow that consumes EPW. The platform supports:
Once Epwforge is connected, these are the calls the assistant has available:
find_station — Search the ~17,000-station GuzzStations catalog by name, country, or coordinates. Optional compact=True returns just the newest TMYx per stationanalyze_weather — Statistical summary of an EPW. Three modes: url= (single file), urls=[] (2–10 file comparison), config={...} (synthesize a morphed scenario fromchart_weather — Inline SVG chart. Single-EPW types: diurnal, temp_carpet, wind_rose, monthly_boxplot, utci_carpet, economizer_carpet, pv_tilt_azimuthgenerate_weather_file — Generate and return a downloadable weather file with the full morph stack. Format = epw / ddy / csv / zip / pvsyst. Supports ensemble=true (all SSPsYou will need 2 environment variables: EPWFORGE_API_KEY, EPWFORGE_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Epwforge's toolset — find_station, analyze_weather, chart_weather and 1 more — is a fair guide to whether it matches your workflow. It is maintained by guzz-labs; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Epwforge's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
| Tool | What it does |
|---|---|
| find_station | Search the ~17,000-station GuzzStations catalog by name, country, or coordinates. Optional compact=True returns just the newest TMYx per station (6–10× smaller responses for chained agent workflows). |
| analyze_weather | Statistical summary of an EPW. Three modes: url= (single file), urls=[] (2–10 file comparison), config={...} (synthesize a morphed scenario from lat/lon — no EPW content returned). Optional include_full_ashrae, include_i |
| chart_weather | Inline SVG chart. Single-EPW types: diurnal, temp_carpet, wind_rose, monthly_boxplot, utci_carpet, economizer_carpet, pv_tilt_azimuth, solar_under_events. Multi-EPW type: comparison. |
| generate_weather_file | Generate and return a downloadable weather file with the full morph stack. Format = epw / ddy / csv / zip / pvsyst. Supports ensemble=true (all SSPs at once). |
