Opentopography

Gives Claude access to OpenTopography's global digital elevation model data through three tools: point_elevation for single coordinates, dem for bounding box rasters returned as GeoTIFF URLs, and datasets to browse available DEM sources. Runs as a streamable HTTP server through Pipeworx's gateway, which means no local setup or API key management. Useful when you need terrain data for GIS analysis, route planning over topography, or watershed modeling. The point_elevation tool returns a 1-pixel raster URL rather than a direct value, so if you just need quick elevation lookups, the note suggests using opentopodata instead.
