Ducks Unlimited Open Data Portal
EnvironmentUSgis.ducks.org
Ducks Unlimited's conservation GIS portal, an ArcGIS Hub instance with 31 items on wetland and waterfowl conservation: keyword search across the catalogue, a datasets-only listing, single-item metadata and the full DCAT-US catalogue feed.
The crw MCP on your computer calls Ducks Unlimited Open Data Portal directly. Calls cost no credits and the data does not pass through fastCRW. Install it once for Claude Code, Cursor, Codex, Windsurf, Gemini CLI or OpenCode, with your fastCRW API key in place of the placeholder:
