## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why list_prefabs is rated Low

This tool retrieves and filters existing prefab files without creating, modifying, deleting, or executing any operations. It is purely informational and poses minimal risk if misused by an AI agent, as it cannot alter game state or cause unintended effects.

From the tool's own definition: "Tool name 'list_prefabs' and description 'List all .prefab files in the project. Filter by name or path' indicate a query/retrieval operation with no side effects."

## Use case

AI agents call list_prefabs to retrieve information from Sbox 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 Sbox:

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