## Why hent_stoysone is rated Low

This tool queries publicly available noise zone maps maintained by Norwegian State Road Administration (Statens vegvesen). It retrieves read-only data about environmental noise coverage based on geographic coordinates. There are no side effects, no data modification, no code execution, and no irreversible actions.

From the tool's own definition: "Tool name 'hent_stoysone' (get/fetch noise zone) and description 'Sjekk om et koordinat ligger i' (check if a coordinate lies in) - performs a lookup/query operation against public Norwegian noise zone data."

## Use case

AI agents call hent_stoysone to retrieve information from Nabolag 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 Nabolag:

```json
{
  "version": "1",
