Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "LP_Get_Elevation_Chart",
    "arguments": {
      "lat": 0,
      "lon": 0,
      "dataset_id": "<dataset_id>"
    }
  }
}
```

## Why LP_Get_Elevation_Chart is rated Low

This tool retrieves geospatial elevation data and generates a visualization of pre-computed statistics. It has no side effects on the underlying data, does not execute arbitrary code, and does not create, modify, or delete records. The requirement for a Pro key is an access control, not a risk elevation. The output format options (PNG/SVG/PDF) are rendering preferences, not risk factors.

From the tool's own definition: "Tool generates and returns a chart image (URL) showing elevation statistics (Min/Avg/Max) across different neighbourhood window sizes. No data modification, deletion, or external command execution occurs."

## Use case

AI agents call LP_Get_Elevation_Chart to retrieve information from Geospatial System — Location Profile without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Geospatial System — Location Profile:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "LP_Get_Elevation_Chart": {}
  }
}
```
