WHAT IT DOES

What rhino_display_mode_set does on Rhino

AI agents invoke rhino_display_mode_set to trigger actions in Rhino. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why rhino_display_mode_set is rated High

This tool drives Rhino's UI by switching the display mode of the active viewport. It is not a simple data read or write; it triggers an external operation in a running application (Rhino 8), affecting the visual state of the environment. While the effect is reversible (you can switch back), it constitutes an Execute-level action as it manipulates an external application's state rather than just data.

From the tool's definition 'Switch the active viewport's display mode' — triggers an external operation in Rhino that changes the active viewport rendering state

RECOMMENDED RULE

The rule that runs rhino_display_mode_set 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_display_mode_set, this is the rule to start with:

rhino_display_mode_set Rate-limited

rhino_display_mode_set stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "counter": "rhino_display_mode_set_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Rhino, apply this rule, and every rhino_display_mode_set call is checked against it from then on.

FAQ

Questions about rhino_display_mode_set

What does the rhino_display_mode_set tool do? +

How do I enforce a policy on rhino_display_mode_set? +

Register the Rhino MCP server in PolicyLayer and add a rule for rhino_display_mode_set: 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_display_mode_set? +

rhino_display_mode_set is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit rhino_display_mode_set? +

Yes. Add a rate_limit block to the rhino_display_mode_set 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_display_mode_set completely? +

Set action: deny in the PolicyLayer policy for rhino_display_mode_set. 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_display_mode_set? +
