batch_create_draft_items · Playfab MCP: Risk & Policy

WHAT IT DOES

What batch_create_draft_items does on Playfab

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

WHY IT NEEDS A POLICY

Why batch_create_draft_items needs a policy

This is a Write operation: it creates or modifies data (draft catalog items) but does not irreversibly delete data or execute arbitrary code. The reversible nature of draft items (they are not published/live) places it in Write rather than Execute. The context of other destructive tools on the server (delete_item, delete_inventory_items) confirms this tool is non-destructive.

From the tool's definition Tool creates draft items in a catalog via 'batch_create_draft_items' — explicitly stated as 'Creates one or more draft items'. Draft items are reversible; they can be modified, deleted, or discarded without affecting live catalog items.
