THE RISK

Low Risk

Why get_supplier needs a policy

This tool retrieves supplier information (contact details and address) without modifying, executing operations, or causing destructive changes. It is a read-only query operation with no side effects. Severity is low because exposure of supplier contact information carries minimal risk compared to other categories, though information disclosure should still be monitored in a security context.

From the tool's definition Get a single supplier by ID. Returns contact details and address.

POLICY

How to control get_supplier

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_supplier:

policy.json

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

get_supplier 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.
