WHAT IT DOES

What stage_upload does on Kockatoos Shopify MCP Server

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

WHY IT NEEDS A POLICY

Why stage_upload needs a policy

This tool facilitates file uploads to Shopify's staging area as the first step of a multi-step upload process. It does not delete or irreversibly destroy data (not Destructive), execute arbitrary code or commands (not Execute), or move money (not Financial). It prepares for data creation/modification rather than immediately executing arbitrary operations.

From the tool's definition stage_upload generates a pre-signed staged upload target for a file, enabling file uploads to Shopify. While uploads themselves are non-destructive and reversible, they can create data in the system and modify file storage state.
