## Why gh_template_list is rated Low

This tool performs a read-only operation that lists available templates and their specifications. It has no side effects, does not execute code, does not modify data, and does not involve financial operations. The operation is informational only, making it a straightforward Read category with low severity.

From the tool's own definition: "Tool name 'gh_template_list' and description 'List bundled Grasshopper templates with their parameter contracts' indicate a query operation that retrieves and displays template metadata without modifying any data."

## Use case

AI agents call gh_template_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": {
    "gh_template_list": {}
  }
}
```
