acl_list_peer_tools Allowed

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

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

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