PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For compare_savings, this is the rule to start with:

compare_savings Allowed

compare_savings is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
