## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `fmt` | string | no | Output format — 'png', 'svg', or 'pdf'. |
| `lat` | number | yes | Latitude in decimal degrees (WGS-84). |

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_Slope_Chart",
    "arguments": {
      "lat": 0,
      "lon": 0,
      "dataset_id": "<dataset_id>"
    }
  }
}
```

## Why LP_Get_Slope_Chart is rated Low

LP_Get_Slope_Chart performs a read-only operation: it computes statistics from geospatial datasets and returns a visualization URL. No data is created, modified, deleted, or written back to the system. No code execution, financial transactions, or destructive operations are involved. The tool requires authentication (Pro key) but this is access control, not a risk escalator.

From the tool's own definition: "Tool generates and returns a chart visualization URL showing terrain slope statistics (Min/Avg/Max). The description explicitly states it 'Returns a URL to the chart image' with no mention of data modification, deletion, or external state changes."

## Use case

AI agents call LP_Get_Slope_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_Slope_Chart": {}
  }
}
```
