RECOMMENDED RULE

The rule that runs plan_announcement_subscription safely

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

plan_announcement_subscription Rate-limited

plan_announcement_subscription 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.
