What rhino_dimension_linear does on Rhino
AI agents use rhino_dimension_linear 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_dimension_linear is rated Medium
This tool creates a new dimension object in the Rhino model, modifying the design document by adding geometry annotations. While this is reversible (dimensions can be deleted), it does alter the model state. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions, so Write is appropriate.
From the tool's definition Tool adds a linear dimension between two points to Rhino. The verb 'Add' combined with the description indicates object creation/addition to the model, which is a reversible write operation. Dimensions are model annotations that can be deleted or modified.
Attacks that exploit this kind of access
The rule that runs rhino_dimension_linear 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_dimension_linear, this is the rule to start with:
rhino_dimension_linear 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_dimension_linear call is checked against it from then on.
Questions about rhino_dimension_linear
Add a linear dimension between two points. 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_dimension_linear: 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_dimension_linear 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_dimension_linear 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_dimension_linear. 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_dimension_linear 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.
