## Why lego_themes is rated Low

This tool performs a simple query operation that retrieves and lists LEGO theme data from the Rebrickable API. It has no capability to modify, delete, execute code, or create financial transactions. The blast radius of misuse is minimal—an agent could at worst retrieve redundant theme listings. This is a straightforward Read category tool.

From the tool's own definition: "Tool name 'lego_themes' and description 'List all LEGO themes from Rebrickable' indicate a data retrieval operation with no side effects."

Risk signals: Handles credentials or secrets (api_key)

## Use case

AI agents call lego_themes to retrieve information from UnClick 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 UnClick:

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