Attacks that exploit this kind of access
The rule that runs edit_voice_settings safely

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