## Why show_pizza_map is rated Low

This tool merely queries and displays information about pizza shop locations. It performs no writes, deletions, code execution, or financial operations. The verb 'display' and the retrieval of map data are characteristic of Read operations. Low severity due to minimal blast radius from misuse—an agent could only view publicly available location information.

From the tool's own definition: "Tool description states 'Display an interactive map of pizza shops in San Francisco' — a read-only operation that retrieves and presents existing location data with no modification, deletion, or external side effects."

## Use case

AI agents call show_pizza_map to retrieve information from Nitrostack 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 Nitrostack:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "show_pizza_map": {}
  }
}
```
