# list_store_categories

Lists all published agentView store categories (e.g. Gastronomie, Wartezimmer, Empfang, Smart Home) with localized titles, descriptions and template counts. Use this to narrow a subsequent search_store_templates call when the user asks for 'templates for a waiting room' or similar. No authentication required. Returns count, language and a categories array where each entry has slug, title, description, templateCount, heroIconKey and detailPath.

```json

  "jsonrpc": "2.0",

## Why list_store_categories is rated Low

This tool queries and returns metadata about store categories. It performs a read-only operation to retrieve structured data (categories, titles, descriptions, template counts) without creating, modifying, deleting, or executing any actions. The description explicitly states 'No authentication required' and the return values are informational only.

From the tool's own definition: "Tool 'lists all published agentView store categories' and 'returns count, language and a categories array' — purely a retrieval operation with no side effects or mutations."

## Use case

AI agents call list_store_categories to retrieve information from agentView 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 agentView:

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