WHAT IT DOES

What rhino_light_add does on Rhino

AI agents use rhino_light_add 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_light_add is rated Medium

This tool creates new light objects in a Rhino document, which is a reversible write operation. While it modifies the document, the changes can be undone and don't involve deletion, financial transactions, or arbitrary code execution.

From the tool's definition Tool adds lights to the Rhino document via 'Add a point / spot / directional / rectangular / linear light to the document', which creates geometric/lighting objects that persist in the document state.

The rule that runs rhino_light_add safely

rhino_light_add Rate-limited

rhino_light_add 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.
