@pipeworx/opentopography

OpenTopography MCP — global DEM (digital elevation) rasters and point queries. Free API key required.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Auth

• Platform: PLATFORM_OPENTOPOGRAPHY_KEY. BYO: ?_apiKey=….

Related MCP server: mcp-osrm

Tools

• point_elevation(lat, lon, dataset?) — elevation at a point (NOTE: OpenTopography's main service returns rasters; this is a one-point convenience that calls their point service)

• dem(dataset, south, north, west, east, format?) — request a DEM raster for a bounding box (returns a download URL)

• datasets() — list available DEM datasets

dataset: SRTMGL1 (default, 30m) | SRTMGL3 (90m) | AW3D30 | NASADEM | COP30 (Copernicus 30m) | COP90.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "opentopography": {
      "url": "https://gateway.pipeworx.io/opentopography/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Opentopography data" })

The gateway picks the right tool and fills the arguments automatically.
