What rhino_text_dot does on Rhino
AI agents use rhino_text_dot 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.
Why rhino_text_dot is rated Medium
This tool creates a new text annotation object (a text dot) in Rhino, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The blast radius is minimal—worst case, unwanted text labels clutter the 3D scene and can be easily deleted. This is a standard geometric/annotation creation operation.
From the tool's definition Tool name 'rhino_text_dot' and description 'Add a small label that always faces the camera in Rhino' indicates creating/adding a visual annotation object in the Rhino 3D environment.
Attacks that exploit this kind of access
The rule that runs rhino_text_dot 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_text_dot, this is the rule to start with:
rhino_text_dot 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Rhino, apply this rule, and every rhino_text_dot call is checked against it from then on.
