What rhino_create_uv_grid does on Rhino
AI agents use rhino_create_uv_grid 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_create_uv_grid is rated Medium
The tool creates new point geometry on a surface at specified UV intervals. This is a reversible modification to the Rhino model (points can be deleted), but not an irreversible destructive action. It does not execute arbitrary scripts, move money, or perform external operations.
From the tool's definition Tool description states 'Create a point grid on a surface' — the verb 'create' indicates generation of new geometry/data within Rhino.
Attacks that exploit this kind of access
The rule that runs rhino_create_uv_grid 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_create_uv_grid, this is the rule to start with:
rhino_create_uv_grid 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_create_uv_grid call is checked against it from then on.

rhino_create_uv_grid is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the rhino_create_uv_grid 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.
