create_draft_item · Playfab MCP: Risk & Policy

WHAT IT DOES

What create_draft_item does on Playfab

AI agents use create_draft_item 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 create_draft_item needs a policy

Creating draft items in a game catalog is a Write operation—it creates new data that can be modified or deleted later. It is not destructive (drafts are not live), does not execute arbitrary code, and does not involve financial transactions. Severity is medium because misuse could clutter the catalog or cause operational issues, but draft items have limited blast radius compared to published items.

From the tool's definition Tool name 'create_draft_item' and description indicate item creation. The deprecation notice references 'batch_create_draft_items', confirming this creates/modifies catalog items in draft state, which are reversible changes.
