The rule that runs observeTokenPermission safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Agentek Eth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For observeTokenPermission, this is the rule to start with:
observeTokenPermission is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
