publish_collection · Shopify Graphql MCP: Risk & Policy

WHAT IT DOES

What publish_collection does on Shopify Graphql

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

WHY IT NEEDS A POLICY

Why publish_collection needs a policy

Publishing a collection changes its visibility and availability on sales channels, which is a data modification action. It is reversible (can be unpublished), so it does not meet the threshold for Destructive. It affects business operations (product discoverability) but does not move money (Financial) or execute arbitrary code (Execute).

From the tool's definition 'Publish a collection to sales channels' — the tool modifies the publication state of a collection, making it visible on specified sales channels. This is a reversible state change (collections can be unpublished).
