import_generated_asset · Blender MCP: Risk & Policy

WHAT IT DOES

What import_generated_asset does on BlenderMCP

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

WHY IT NEEDS A POLICY

Why import_generated_asset needs a policy

Importing an asset into a Blender scene creates new objects/data in the project—a reversible Write operation. It modifies the scene state but does not execute arbitrary code (Execute), delete data (Destructive), or move funds (Financial). Severity is medium because uncontrolled asset imports could bloat scenes or introduce unwanted models, but the operation is reversible via undo.

From the tool's definition Tool name 'import_generated_asset' indicates creating/adding assets to a Blender scene. Description is empty, limiting certainty.

import_generated_asset Rate-limited

import_generated_asset 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.
