WHAT IT DOES

What viewport_focus_object does on Blender Copilot MCP Server

AI agents invoke viewport_focus_object to trigger actions in Blender Copilot MCP Server. 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 viewport_focus_object is rated High

This tool triggers a viewport action in Blender (zooming/focusing the camera view), which is an external application operation rather than a simple data read. It doesn't read, write, or delete data, but executes a UI/viewport action in Blender. Severity is low as misuse has minimal blast radius.

RECOMMENDED RULE

The rule that runs viewport_focus_object safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Blender Copilot MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For viewport_focus_object, this is the rule to start with:

viewport_focus_object Rate-limited

viewport_focus_object 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.

          "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 Blender Copilot MCP Server, apply this rule, and every viewport_focus_object call is checked against it from then on.
