RECOMMENDED RULE

The rule that runs system_preferences_set safely

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

system_preferences_set Rate-limited

system_preferences_set 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.
