What rhino_clipping_plane does on Rhino
AI agents use rhino_clipping_plane 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_clipping_plane is rated Medium
This tool creates (adds) a new clipping plane object in the Rhino 3D environment and applies it to viewports. This is a reversible write operation — clipping planes can be deleted or modified. It does not delete data (not Destructive), execute arbitrary code (not Execute), nor involve financial transactions (not Financial).
From the tool's definition Tool performs 'Add a clipping plane to all viewports' — a viewport-modifying operation that creates and applies a new clipping plane object across multiple viewports.
Attacks that exploit this kind of access
The rule that runs rhino_clipping_plane 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_clipping_plane, this is the rule to start with:
rhino_clipping_plane 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_clipping_plane call is checked against it from then on.
Questions about rhino_clipping_plane
Add a clipping plane to all viewports. 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_clipping_plane: 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_clipping_plane 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_clipping_plane 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_clipping_plane. 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_clipping_plane 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.
