What rhino_curve_length does on Rhino
AI agents call rhino_curve_length to retrieve information from Rhino without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why rhino_curve_length is rated Low
This tool only retrieves geometric properties (parametric domain and length) of an existing curve. It has no side effects and does not modify, create, or delete any data.

Attacks that exploit this kind of access
The rule that runs rhino_curve_length 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_curve_length, this is the rule to start with:
rhino_curve_length is read-only, so it stays allowed. 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_curve_length call is checked against it from then on.
Questions about rhino_curve_length
Return the curve's parametric domain and approximate length. It is categorised as a Read tool in the Rhino MCP Server, which means it retrieves data without modifying state.
Register the Rhino MCP server in PolicyLayer and add a rule for rhino_curve_length: 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_curve_length is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the rhino_curve_length 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_curve_length. 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_curve_length 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.
