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

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

## Why blender_list_tools is rated Low

The tool name contains 'list', which is a classic Read operation that retrieves information about available Blender tools without modifying, executing, or destroying anything. The empty description prevents higher confidence, but the naming pattern is clear. This would typically be used for discovery purposes only.

From the tool's own definition: "Tool name 'blender_list_tools' indicates enumeration/listing of available tools. No description provided, but the 'list' verb strongly suggests data retrieval without side effects."

## Use case

AI agents call blender_list_tools to retrieve information from Blender 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 Blender:

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