RECOMMENDED RULE

The rule that runs compare_notes safely

compare_notes Allowed

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

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