WHAT IT DOES

What rhino_text does on Rhino

AI agents use rhino_text 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.

RISK

Why rhino_text is rated Medium

This tool creates and adds text annotations to a Rhino 3D model, which is a reversible write operation. It modifies the model state by introducing new geometry, but the changes can be undone (unlike destructive operations). The severity is medium because misuse could clutter or obscure a model with unwanted annotations, but the impact is localized and reversible.

From the tool's definition Tool name 'rhino_text' and description 'Add 3D text annotation' indicate creation of new geometric objects in Rhino that persist in the model.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs rhino_text 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_text, this is the rule to start with:

rhino_text Rate-limited

rhino_text 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.

FAQ

Questions about rhino_text

What does the rhino_text tool do? +

Add 3D text annotation. Bridge mode honours the active dim style; standalone uses text-dot fallback. 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.

How do I enforce a policy on rhino_text? +

Register the Rhino MCP server in PolicyLayer and add a rule for rhino_text: 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.

What risk level is rhino_text? +

rhino_text is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit rhino_text? +

Yes. Add a rate_limit block to the rhino_text 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.

How do I block rhino_text completely? +

Set action: deny in the PolicyLayer policy for rhino_text. 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.

What MCP server provides rhino_text? +

rhino_text 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.
