Choose a provisional Character voice

character_voice_autoselect: permissions and generated input/output contracts.

character_voice_autoselect · Gateway release 0.8.3

Choose and save a suitable existing workspace voice from a brief preference, without asking the user for a voice ID or claiming anyone listened to a preview. Saves the actual Character default and synchronizes its Bible; the choice is provisional and can be changed later in Studio. Preserves an already-saved default. No cloning, importing, speech generation or billing. Retry only the same operationId; uncertain assignment is reconciled using its MCP-linked audit revision, never silently repeated. Use this for delegated automatic creation; character_voice_assign retains its manual preview-review requirement.

Required scopes: account:read, studio:write. Changes saved state or requests work; review the operation’s effects.

Availability depends on runtime configuration and the permissions granted to this connection. Use live MCP discovery as the authority.
