AI agents call customers to retrieve information from Saleor MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves customer data from a Saleor Commerce instance through a read-only API. It has no side effects, cannot modify or delete data, and presents no destructive or financial risk. The server's read-only design and the tool's position among other retrieval functions (orders, products, stocks, warehouse_details) confirm this is a data query operation.
From the tool's definition Server description explicitly states 'read-only GraphQL API integration' and 'fetch data about products, customers, and orders'. Tool name 'customers' aligns with fetching customer data.
Documented attack patterns abuse exactly the kind of access customers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Saleor MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for customers:
{
"version": "1",
"default": "deny",
"tools": {
"customers": {}
}
}customers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

customers. It is categorised as a Read tool in the Saleor MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Saleor MCP Server MCP server in PolicyLayer and add a rule for customers: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Saleor MCP Server. Nothing to install.
customers is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the customers rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for customers. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
customers is provided by the Saleor MCP Server MCP server (saleor/saleor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Saleor MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
