AI agents use complete-draft-order to create or update resources in Shopify MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify MCP Server environment.
Completing a draft order finalizes it into a real order, which is a significant write action that creates a binding purchase commitment. While it may involve financial implications (committing to a sale), it is primarily an order state transition (Write) rather than directly moving money.

"version": "1",
"default": "deny",

"complete-draft-order": {
"limits": [
{
"counter": "complete-draft-order_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
