What rhino_panelize_surface does on Rhino
AI agents use rhino_panelize_surface 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_panelize_surface is rated Medium
This tool modifies geometry by creating a panelized version of a surface—a reversible transformation that adds new objects to the model. It does not execute arbitrary code, delete data, or cause financial impact. While it alters the state of the Rhino document, the changes can be undone (standard CAD undo), placing it in the Write category.
From the tool's definition Tool description states it will 'Subdivide a surface into panels', which creates new geometric data in Rhino. The sibling tools include 'gh_bake_to_rhino' indicating persistence of modifications to the Rhino model.
Attacks that exploit this kind of access
The rule that runs rhino_panelize_surface 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_panelize_surface, this is the rule to start with:
rhino_panelize_surface 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_panelize_surface call is checked against it from then on.
Questions about rhino_panelize_surface
Subdivide a surface into panels (quad, triangle, or diamond). It is categorised as a Write tool in the Rhino MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Rhino MCP server in PolicyLayer and add a rule for rhino_panelize_surface: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Rhino. Nothing to install.
rhino_panelize_surface 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_panelize_surface 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.
Set action: deny in the PolicyLayer policy for rhino_panelize_surface. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
rhino_panelize_surface is provided by the Rhino MCP server (easehee/rhino-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
