blender_import_asset · ClaudeKit Blender MCP: Risk & Policy

WHAT IT DOES

What blender_import_asset does on ClaudeKit Blender MCP

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

WHY IT NEEDS A POLICY

Why blender_import_asset needs a policy

This tool performs a Write operation: it imports and inserts 3D assets into a Blender scene, creating new scene objects. While reversible (assets can be deleted), the modification is material enough to warrant Write classification.

From the tool's definition "Import external 3D assets into Blender scene" and "Import confirmation with object details" — the tool creates or adds new objects/data to the Blender scene, modifying its state reversibly.
