RECOMMENDED RULE

The rule that runs lib_add_pins safely

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

lib_add_pins Rate-limited

lib_add_pins 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.
