Pack: opentopography · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/point_elevation for the schema, then POST the same URL with its arguments for the data.

Elevation at a point (returns a 1-pixel raster URL — use opentopodata for direct point values).
