# hent_grontareal

Grøntareal rundt et koordinat (WGS84) fra to åpne kilder: (1) FKB-AR5 arealtype på selve punktet (bebygd/skog/dyrka/myr osv., NIBIO) og (2) avstand til nærmeste offentlige park-/turområde (SSB, ekspanderende søk 250 m → 2 km). NB: SSB-polygonene er navnløse og dekker primært tettsteder —

## Why hent_grontareal is rated Low

This tool retrieves and queries public geospatial data around a location without side effects. It performs lookups against existing datasets (land classification and park proximity), similar to a search or fetch operation. No data is created, modified, deleted, or overwritten. No code execution or financial transactions occur.

From the tool's own definition: "Tool description explicitly states it 'queries' (hent = retrieve/fetch) open Norwegian neighborhood data: land-use types from FKB-AR5 (NIBIO) and distances to public parks (SSB). No modification, deletion, or command execution."

## Use case

AI agents call hent_grontareal 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",
  "default": "deny",
  "tools": {
    "hent_grontareal": {}
  }
}
```
