camera_move · Open Brush MCP Server MCP: Risk & Policy

WHAT IT DOES

What camera_move does on Open Brush MCP Server

AI agents use camera_move to create or update resources in Open Brush MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Open Brush MCP Server environment.

WHY IT NEEDS A POLICY

Why camera_move needs a policy

This tool repositions the camera to a specific location in the 3D scene. It modifies state (camera position) but is reversible by moving the camera back. No data is deleted, no code is executed, and there are no financial implications. The blast radius is low as it only affects the viewport/camera position within a 3D painting application.

Verdict

camera_move Rate-limited

camera_move 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.
