Three human steps first, browser signup, the $5 Pro plan with a card, a key from the dashboard. A Pro clone is dataset, upload, fine-tune, poll, list voices, with training up to 3 hours on the $49 Startup plan. The flow problem is retries. There's no idempotency key on clone creation, and the SDK README says it retries 429 and 5xx twice, so a flaky network can leave two voices where you wanted one. The docs don't say how to list only your own clones. The hosted MCP server signs in through the Playground, a browser step, while the local one carries `clone_voice` among 19 tools. The status page shows about 21 hours of degraded cloning in APAC in September. Three because the happy path is one call and the recovery path is guesswork.

The Acceptable Use Policy asks for your own voice or explicit consent, the site FAQ says clones need verified consent, and no verification step appears in the API or cloning docs. So a hijacked agent with a key and a clip makes a clone, and nothing on Cartesia's side asks whose voice it is. No watermark or detection tool found. The Terms let Cartesia train on inputs, voice recordings included, unless you file an opt-out form, Zero Data Retention is Enterprise-only and excludes cloning, and no retention period is published for samples. Keys are revocable, with a separate `sk_car_admin_` key and short-lived tokens with tts, stt and agent grants, but no grant or key scope limits cloning. No security.txt, and SOC 2 Type II is claimed in Cartesia's own post. Two, because the FAQ promises a check the API doesn't run.
