Epwforge is a remote MCP server that gives an AI agent 6 tools, among them analyze_weather, chart_weather, explore_design_conditions. It answers at https://epwforge.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
EPW/DDY weather files - TMY/AMY/CMIP6 morphing, UHI, events, smoke. 3 of 4 tools anon-free.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
analyze_weather | 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 Inputs: url, urls, config, compact, include_full_ashrae, include_improbability |
chart_weather | 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 Inputs: url, urls, config, chart_type, resolution, econ_mode |
explore_design_conditions | 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 Inputs: lat, lon, ssp, year, percentile, uhi |
find_station | Search the GuzzStations catalog (17,000+ weather stations worldwide, self-hosted mirror of OneBuilding TMYx). Returns matching stations with EPW URLs ready to pass to analyze_weather or chart_weather. Optionally enriches with AMY extreme ye Inputs: query, lat, lon, country, site_elevation_m, max_results |
generate_weather_file | Generate and deliver an EPW or DDY file. 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 fr Inputs: lat, lon, basis, amy_year, ssp, year |
preview_forge_bundle | Preview a fixed-price Forge bundle for a location — the no-account way to buy weather files. Returns the exact scenario breakdown, file count, price, and a purchase link the user opens for guest checkout. Bundles: Carbon (10 scenarios), Tit Inputs: bundle_id, lat, lon, location |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://epwforge.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
