Top selling products by revenue or quantity within a date range, walking line_items across all matching orders.
AI agents call top_products 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 performs analytics/reporting on existing data (sales figures, order line items) within a specified date range. It has no side effects, does not modify data, execute code, delete records, or involve financial transactions. It is a straightforward data retrieval and aggregation operation, fitting the Read category with low severity since unauthorized access would only expose historical sales metrics.
From the tool's definition The tool description states it retrieves 'top selling products by revenue or quantity within a date range' through 'walking line_items across all matching orders.' The verbs 'retrieves' and 'walking' (iterating through data) indicate data querying without…
Documented attack patterns abuse exactly the kind of access top_products 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_products:
{
"version": "1",
"default": "deny",
"tools": {
"top_products": {}
}
}top_products is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Top selling products by revenue or quantity within a date range, walking line_items across all matching orders. 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_products: 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_products 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_products 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_products. 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_products 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.
