RECOMMENDED RULE

The rule that runs link_device_pin safely

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

link_device_pin Rate-limited

link_device_pin stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
