THE RISK

Low Risk

Why get_product_info needs a policy

This tool retrieves and queries product information from the grocery store database without creating, modifying, deleting, or executing any operations. It has no capability to alter cart state, process payments, or trigger external actions. The data returned is public product metadata. This is a straightforward Read operation with minimal security risk.

From the tool's definition Tool description explicitly states it 'Gets detailed info' for products including nutritional values, weight, ingredients, and price. The verb 'Gets' and the nature of the data (static product information) indicate a retrieval operation with no side effects.

POLICY

How to control get_product_info

PolicyLayer is an MCP gateway — it sits between your AI agents and Frisco MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_product_info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_product_info": {}
  }
}

get_product_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Frisco MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
