Terrain elevation and terrain analysis from two keyless sources: USGS 3DEP (the 3D Elevation Program) for the US, its territories, and much of Canada and Mexico at 1–30 m, and Open Topo Data everywhere else, which answers from SRTM (about 30 m, land between 60°N and 56°S) and, beyond SRTM, Mapzen terrain tiles (global, including high latitudes and the sea floor). The default source, auto, uses 3DEP wherever it has data and Open Topo Data for the remaining points; every point, sample, and grid cell names the dataset that answered (usgs_3dep, srtm30m, or mapzen) and, except for mapzen, its…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

elevation_get_grid unknown 6h ago

Sample a regular grid of terrain elevations across a bounding box and report the highest and lowest sampled points, the mean elevation, and the relief, plus the full elevation matrix with each cell's dataset. Values are point samples at grid nodes (box edges included), not cell averages, so a summit between nodes is missed; to refine a candidate high or low point, call again with a smaller box around it. Over open water, Mapzen cells are sea-floor depths. Rows times columns may not exceed 250.

elevation_get_points unknown 6h ago

Look up ground elevation at up to 100 coordinates in one call, in meters and feet, with the dataset and resolution behind every point. Inside USGS 3DEP coverage (the US and its territories, plus much of Canada and Mexico) values come from 3DEP at 1–30 m resolution. Elsewhere they come from Open Topo Data: SRTM at about 30 m on land between 60°N and 56°S, and Mapzen terrain tiles beyond SRTM's coverage and over the ocean, where values below 0 m are sea-floor depths. A point with no data in any queried dataset returns status no_data instead of failing the call.

elevation_get_profile unknown never probed

Sample terrain elevation at evenly spaced points along a route (a polyline of 2–1,000 vertices) and summarize it. Returns total distance, cumulative ascent and descent, start, end, minimum, and maximum elevation, and the steepest climb and descent grades, plus the per-sample profile with each sample's dataset unless include_samples is false. Ascent and descent are summed between samples, so they depend on the sample spacing reported in the result: denser sampling captures more small climbs, down to the source's resolution. Over open water, Mapzen samples are sea-floor depths. Each USGS 3DEP sample is a separate upstream request, so up to 250 samples take roughly 10–30 seconds.

elevation_check_line_of_sight unknown 6h ago

Check whether terrain blocks the straight sightline between an observer and a target, each at a height above the ground, accounting for earth curvature and atmospheric refraction. Returns a verdict of clear, blocked, or indeterminate (when samples along the line have no data), the minimum clearance and the terrain point that limits it, and the first obstruction from the observer when blocked. With frequency_mhz, it also reports first Fresnel zone clearance against the 60% free-space bar. Where Mapzen reports sea-floor depth over open water, clearance is measured to the sea surface; USGS 3DEP values below 0 m (bay floor in some bays, or dry land) count as received unless water_surface_m sets a water level. Models terrain only: buildings and vegetation are not modeled beyond what the elevation source itself captures, and a ridge narrower than the reported sample spacing can be missed. To see the terrain between the points, call elevation_get_profile on the same two points.

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
