## Why sok_kommune is rated Low

This tool retrieves municipality and county information for a geographic coordinate (WGS84) from a read-only API. It performs a straightforward lookup with no capacity to modify, delete, or execute external operations. The blast radius of misuse is minimal—returning incorrect geographic metadata poses no security or safety risk.

From the tool's own definition: "Tool name 'sok_kommune' (lookup municipality) and description 'Slå opp kommune og fylke' (look up municipality and county) indicate a query/lookup operation."

## Use case

AI agents call sok_kommune to retrieve information from Kartverket 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)

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

    "sok_kommune": {}
  }
