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

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

## Why rhino_cone is rated Medium

This tool creates a new geometric primitive (cone) in the Rhino 3D modeling environment. Creating geometry is a reversible write operation—the created cone can be modified, moved, or deleted by subsequent operations. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions.

From the tool's own definition: "Tool description states 'Add a cone primitive', indicating creation of geometry objects in Rhino 8. The verb 'add' confirms data creation rather than retrieval or deletion."

## Use case

AI agents use rhino_cone to create or update resources in Rhino, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rhino environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Rhino:

```json

  "default": "deny",
  "tools": {
    "rhino_cone": {
