RECOMMENDED RULE

The rule that runs generate_password safely

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

generate_password Rate-limited

generate_password 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.
