RECOMMENDED RULE

The rule that runs add_timeline_marker safely

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

add_timeline_marker Rate-limited

add_timeline_marker 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.
