RECOMMENDED RULE

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

viewport_delete Hidden

viewport_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
