RECOMMENDED RULE

The rule that runs use_portal_magic safely

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

use_portal_magic Rate-limited

use_portal_magic 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.
