opentopodata.elevation.point
Get land surface elevation (metres above sea level) for a single latitude/longitude coordinate. Supports three global datasets: srtm90m (NASA SRTM 90m resolution, default), srtm30m (NASA SRTM 30m), and aster30m (ASTER 30m, best for high-altitude regions like Everest). Returns elevation in metres ...

What opentopodata.elevation.point does on Apibase
AI agents call opentopodata.elevation.point to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
lat | number | Yes | Latitude of the point (-90 to 90) |
lon | number | Yes | Longitude of the point (-180 to 180) |
dataset | string | — | Elevation dataset: srtm90m (NASA SRTM 90m, default), srtm30m (NASA SRTM 30m), aster30m (ASTER 30m, good for high mountains) |
interpolation | string | — | Interpolation method: bilinear (default, smoother) or nearest (raw pixel value) |
Parameters from the server's own tool schema.
Why opentopodata.elevation.point is rated Low
Retrieves public geospatial elevation data without modification or side effects.
From the tool's definition Get land surface elevation for a single latitude/longitude coordinate. Returns elevation in metres.
Attacks that exploit this kind of access
The rule that runs opentopodata.elevation.point safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For opentopodata.elevation.point, this is the rule to start with:
opentopodata.elevation.point is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every opentopodata.elevation.point call is checked against it from then on.
Questions about opentopodata.elevation.point
Get land surface elevation (metres above sea level) for a single latitude/longitude coordinate. Supports three global datasets: srtm90m (NASA SRTM 90m resolution, default), srtm30m (NASA SRTM 30m), and aster30m (ASTER 30m, best for high-altitude regions like Everest). Returns elevation in metres with the dataset name and the snapped coordinates. Use for terrain analysis, hiking route planning, flight-path clearance checks, and GIS workflows. MIT licence, no auth, no upstream cost. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
opentopodata.elevation.point accepts 4 parameters: lat, lon, dataset, interpolation. Required: lat, lon. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for opentopodata.elevation.point: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apibase. Nothing to install.
opentopodata.elevation.point is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the opentopodata.elevation.point rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for opentopodata.elevation.point. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
opentopodata.elevation.point is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
