AI agents call get-customers to retrieve information from Shopify MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves customer data from Shopify without modifying, creating, or deleting records. While classified as Read (lowest category), the severity is high because customers list may include PII (names, emails, addresses, phone numbers, purchase history) that could be exposed to an AI agent without proper access controls.
From the tool's definition Tool name 'get-customers' and description 'Get shopify customers with pagination support' indicate data retrieval with no modification or deletion. The verb 'get' is a read operation.
Documented attack patterns abuse exactly the kind of access get-customers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Shopify MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get-customers:
{
"version": "1",
"default": "deny",
"tools": {
"get-customers": {}
}
}get-customers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
