## Why volcano.status.elevated is rated Low

Tool retrieves real-time volcano status data from USGS without modifying any systems or data.

From the tool's own definition: "Get all US volcanoes currently in elevated state, returns volcano data, no side effects."

## Use case

AI agents call volcano.status.elevated 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "volcano.status.elevated": {}
  }
}
```
