Why get_customer needs a policy

This tool retrieves customer information and metadata (address list, order count) without creating, modifying, deleting, or executing any operations. It is a straightforward query operation with no side effects, fitting the Read category.

From the tool's definition Tool name 'get_customer' and description 'Get a single customer by ID, including their address list and order count' explicitly indicate retrieval of customer data with no modification or deletion.

POLICY

How to control get_customer

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 get_customer:

policy.json

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

get_customer 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 Sapo — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
