What rhino_sweep1 does on Rhino
AI agents use rhino_sweep1 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_sweep1 is rated Medium
This tool creates new 3D geometry (a sweep surface) in Rhino, which is a reversible write/creation operation. It does not delete existing data, execute arbitrary code, or involve financial transactions. Misuse could clutter the scene with unintended geometry but is easily undone.
From the tool's definition 'Sweep profiles along a single rail' — creates new geometry in Rhino by sweeping profile curves along a rail curve
Attacks that exploit this kind of access
The rule that runs rhino_sweep1 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_sweep1, this is the rule to start with:
rhino_sweep1 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_sweep1 call is checked against it from then on.
Questions about rhino_sweep1
Sweep profiles along a single rail. 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_sweep1: 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_sweep1 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_sweep1 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_sweep1. 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_sweep1 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.
