RECOMMENDED RULE

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

system_capabilities Allowed

system_capabilities is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "system_capabilities": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AutoCAD MCP Pro, apply this rule, and every system_capabilities call is checked against it from then on.
