RECOMMENDED RULE

The rule that runs invite_user safely

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

invite_user Rate-limited

invite_user 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.
