Execute Shopify Storefront GraphQL queries.

This tool allows execution of arbitrary GraphQL queries against a Shopify Storefront API. While GraphQL queries themselves may be read-only in some cases, the tool's design permits any valid query—including those that modify carts, process orders, or extract sensitive customer and product data.
From the tool's definition Tool explicitly performs 'Execute Shopify Storefront GraphQL queries' — a direct execution of arbitrary queries against a live Shopify API endpoint. The description confirms the tool runs queries (execute) rather than merely retrieving predefined data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Shopify Storefront MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for shopify_storefront_graphql:
{
"version": "1",
"default": "deny",
"tools": {
"shopify_storefront_graphql": {
"limits": [
{
"counter": "shopify_storefront_graphql_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} shopify_storefront_graphql stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
