WHAT IT DOES

What rhino_sun_path does on Rhino

AI agents use rhino_sun_path 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_sun_path is rated Medium

The tool creates geometry (polylines) in the Rhino environment. This is a Write operation as it creates new visual/geometric data in the scene. It does not delete existing data and can be undone, making it reversible. Misuse could clutter the scene with unwanted geometry but has limited blast radius.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs rhino_sun_path 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_sun_path, this is the rule to start with:

rhino_sun_path Rate-limited

rhino_sun_path 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.
