What this MCP does

Splits and cleans audio, trains private RVC voice models, imports models, and performs vocal conversion with downloadable outputs.

create_free_audio_job
Split or clean up audio for free
Split stems, isolate vocals, or remove noise or reverb. No account needed. All four audio tools share 10 free minutes per rolling 24 hours; subscribers have unlimited use. Returns an upload URL, then use get_free_audio_job.

create_training_job
Create an RVC training upload
Creates a private NiceVois job and returns a one-time PUT upload URL. Do not ask for consent before the first attempt because NiceVois remembers the current standing account agreement. If the server returns CONSENT_REQUIRED, ask for one acceptance of the linked standing agreement and retry once with acceptsStandingAgreement=true. This allocates a private training slot but does not start GPU work until the audio is uploaded and start_training is called.

get_voice_conversion
Check an RVC vocal conversion
Use this when checking one private NiceVois conversion. Poll no more than once every 10 seconds. Report the returned stage without inventing progress. When complete, present the NiceVois cleaned version first and use download_voice_conversion_output for the version the user requests.
