WHAT IT DOES

What rhino_twist does on Rhino

AI agents use rhino_twist 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.

RISK

Why rhino_twist is rated Medium

This tool modifies existing geometry by applying a twist transformation. It creates or modifies data (geometry) reversibly — the operation changes object state but the original could be restored. It does not delete data, execute arbitrary code, or involve financial transactions, so Write is the appropriate category.

RECOMMENDED RULE

The rule that runs rhino_twist safely

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

rhino_twist Rate-limited

rhino_twist stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
