create_metaobject · AdminAgent MCP: Risk & Policy

WHAT IT DOES

What create_metaobject does on AdminAgent

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

WHY IT NEEDS A POLICY

Why create_metaobject needs a policy

The 'create_' prefix unambiguously indicates object creation, which is a reversible Write operation. In Shopify, metaobjects are custom data structures; creating them modifies the store's data model but is reversible via deletion. High severity assigned due to potential bulk scope (admin context) and Shopify integration.

From the tool's definition Tool name 'create_metaobject' indicates creation of data via 'create' verb. Empty description limits certainty.
