RECOMMENDED RULE

The rule that runs calendar_create_event safely

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

calendar_create_event Rate-limited

calendar_create_event 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Dialogbrain, apply this rule, and every calendar_create_event call is checked against it from then on.
