WHAT IT DOES

What model_icosa_import does on Open Brush MCP Server

AI agents use model_icosa_import 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 model_icosa_import needs a policy

Importing a 3D model into a painting application creates new data structures in the document and modifies the scene. This is a reversible operation (the imported model can be deleted or undone) so it falls under Write rather than Destructive. While it executes an operation, the outcome is primarily data creation/modification rather than code execution with unpredictable effects, distinguishing it from Execute.

From the tool's definition Tool name 'model_icosa_import' and description 'Imports a model from Icosa Gallery' indicate the tool creates or adds new content (3D models) into Open Brush's canvas/scene.
