## Why datasets_numbeo_cities_search is rated Low

Even though datasets_numbeo_cities_search only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: High parameter count (14 properties)

## Use case

AI agents call datasets_numbeo_cities_search to retrieve information from Crawlora 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 Crawlora:

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