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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "rhino_layer_list",
    "arguments": {}
  }
}
```

## Why rhino_layer_list is rated Low

This tool retrieves and displays layer metadata (color, visibility, object count) from Rhino without altering any data. It is a passive read operation analogous to 'list' or 'get' operations. There are no side effects, no data modification, and no irreversible actions. Severity is low because misuse poses minimal risk—an agent can only view existing layer information.

From the tool's own definition: "Tool name 'rhino_layer_list' and description 'List all layers with their properties' indicate a query/retrieval operation with no modification capability."

## Use case

AI agents call rhino_layer_list to retrieve information from Rhino 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 Rhino:

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