Top customers ranked by total revenue or order count within a date range. Guests grouped by email/phone.
AI agents call top_customers to retrieve information from Sapo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves customer analytics (rankings, revenue metrics, order counts) without creating, modifying, deleting, or executing any operations. It is a read-only reporting/analysis function that has minimal security risk even if misused by an AI agent, as it only exposes existing aggregated business metrics.
From the tool's definition Tool description states it 'ranked by total revenue or order count within a date range' and 'grouped by email/phone' - purely retrieves and aggregates customer data with no modification or execution capabilities.
Documented attack patterns abuse exactly the kind of access top_customers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sapo, and nothing reaches the server without passing your rules. This is the rule we recommend for top_customers:
{
"version": "1",
"default": "deny",
"tools": {
"top_customers": {}
}
}top_customers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Top customers ranked by total revenue or order count within a date range. Guests grouped by email/phone. It is categorised as a Read tool in the Sapo MCP Server, which means it retrieves data without modifying state.
Register the Sapo MCP server in PolicyLayer and add a rule for top_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 Sapo. Nothing to install.
top_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 top_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 top_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.
top_customers is provided by the Sapo MCP server (nguyennguyenit/sapo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sapo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
