Earth 2 Elevation MCP

What Earth-2 Elevation MCP MCP server does

The Earth-2 Elevation MCP MCP server exposes Open-Elevation lookup operations as MCP tools. It accepts latitude and longitude values and returns elevation data in meters. The available operations cover a single coordinate, a list of coordinates, and a path profile between two endpoints.

This arrangement lets an MCP-compatible client request terrain elevation through the server instead of calling the Open-Elevation HTTP endpoint directly. The server is intended to run locally and communicate with the client over standard input and output.

How it works

Open-Elevation provides a POST lookup endpoint at /api/v1/lookup. The server sends locations in the API's expected structure, with each location represented by a latitude and longitude. Results are returned in the same order as the requested locations and include the coordinates together with the elevation value.

get_elevation handles one point. get_elevations handles multiple points in one request. get_elevation_profile samples points evenly along the line between two supplied coordinates, producing a sequence that can be used as a route elevation profile.

Setup and configuration

To run the Earth-2 Elevation MCP MCP server, use the repository's npm start command or invoke its JavaScript entry point directly:

npm start
node .\src\index.js

Add the process to the MCP client's server configuration with node as the command and the local entry point as its argument. The example configuration sets OPEN_ELEVATION_BASE_URL to https://api.open-elevation.com; adjust the entry-point path for the local installation. The environment variable provides the base address used for Open-Elevation requests.

The supplied configuration is for a Windows path, but the important requirements are the same on other systems: point the client at the server's entry file and provide the Open-Elevation base URL.

Tools and capabilities

• get_elevation: Looks up elevation for one latitude and longitude pair.
• get_elevations: Looks up elevations for multiple coordinate pairs.
• get_elevation_profile: Generates an elevation sequence by evenly sampling between two coordinates.

All elevation values are expressed in meters. Batch results preserve the order of the requested locations, which allows callers to match each result to its input coordinate. Profile results are intended for comparing elevation changes along a route between two points.

Limitations and notes

The Earth-2 Elevation MCP MCP server depends on the Open-Elevation service and its lookup endpoint. It does not provide a separate elevation dataset in the repository. If Open-Elevation has no recorded elevation for a coordinate, the service returns 0 meters, which represents sea level in that response rather than necessarily confirming the location's actual elevation.

The base URL should therefore point to an endpoint compatible with the documented Open-Elevation lookup request format.
