WHAT IT DOES

What list_views does on Aos

AI agents call list_views to retrieve information from Aos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_views is rated Low

This tool queries and returns information about views in a Rhino document without creating, modifying, deleting, or executing any operations. It has no side effects and falls squarely into the Read category with low severity since it only exposes metadata about the document state.

From the tool's definition Tool name is 'list_views' and description states 'List all named views in the document plus the currently active view.' The verb 'list' and action of retrieving/querying view metadata with no modifications indicate a read-only operation.

RECOMMENDED RULE

The rule that runs list_views safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_views, this is the rule to start with:

list_views Allowed

list_views is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_views": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every list_views call is checked against it from then on.
