RECOMMENDED RULE

The rule that runs create_calendar safely

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

create_calendar Rate-limited

create_calendar 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.
