Why lookup_zip is rated Low
This tool performs a simple geographic data retrieval operation with no side effects. It queries public ZIP code information and returns static reference data (city, state, coordinates). There is no data creation, modification, deletion, code execution, or financial transaction involved.

Attacks that exploit this kind of access
The rule that runs lookup_zip safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GoCreative Agent API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_zip, this is the rule to start with:
lookup_zip is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GoCreative Agent API, apply this rule, and every lookup_zip call is checked against it from then on.
