RECOMMENDED RULE

The rule that runs execute_message_pin 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 execute_message_pin, this is the rule to start with:

execute_message_pin Rate-limited

execute_message_pin 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.
