camera_translate · Open Brush MCP Server MCP: Risk & Policy

WHAT IT DOES

What camera_translate does on Open Brush MCP Server

AI agents invoke camera_translate to trigger actions in Open Brush 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.

WHY IT NEEDS A POLICY

Why camera_translate needs a policy

The tool moves the camera in the Open Brush 3D painting software. This is an external operation that changes the state of a running application, making it Execute category. The blast radius is low since it only affects the viewport/camera position and does not create, delete, or modify artwork data directly.

From the tool's definition 'Moves camera relatively' — triggers an external operation (camera movement) in the Open Brush application via HTTP API
