List all named views in the document plus the currently active view.
AI agents call list_views to retrieve information from GOLEM-3DMCP-Rhino- without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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.
Documented attack patterns abuse exactly the kind of access list_views gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GOLEM-3DMCP-Rhino-, and nothing reaches the server without passing your rules. This is the rule we recommend for list_views:
{
"version": "1",
"default": "deny",
"tools": {
"list_views": {}
}
}list_views is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all named views in the document plus the currently active view. It is categorised as a Read tool in the GOLEM-3DMCP-Rhino- MCP Server, which means it retrieves data without modifying state.
Register the GOLEM-3DMCP-Rhino- MCP server in PolicyLayer and add a rule for list_views: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GOLEM-3DMCP-Rhino-. Nothing to install.
list_views is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_views rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_views. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_views is provided by the GOLEM-3DMCP-Rhino- MCP server (thekinghippopotamus/golem-3dmcp-rhino-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GOLEM-3DMCP-Rhino-, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
