What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • get_training_requirements

    Use this before training an AI voice to confirm NiceVois input formats, duration and epoch limits, consent requirements, outputs, retention, and the exact upload workflow.

  • get_training_account

    Call before quoting or creating a training job. Returns the connected account's welcome-credit status, available and reserved balance, balance packs, and a private browser link that keeps checkout on this same agent identity.

  • quote_training

    Call after inspecting the audio and before creating a job. Returns the exact payable amount, current balance, welcome-credit effect, shortfall, feasibility, and the private balance-page link when more balance is needed.

  • create_training_job

    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

  • start_training

    Use this only after the source audio was successfully PUT to the upload URL returned by create_training_job. Starts the private cloud RVC training job.

  • get_training_job

    Use this to check truthful stage, completed epochs, ETA, and artifact readiness for one private NiceVois training job. Poll reasonably; do not call more often than every 15 seconds.

  • list_training_jobs

    Use this to find the authenticated user's recent NiceVois jobs before asking for a job ID they may not know.

  • get_conversion_requirements

    Use this when a user wants to convert vocals with RVC or compare a normal RVC result with NiceVois cleaned consonants and breaths. Returns the real input formats, model choices, workflow, current free-beta policy, and outputs.

  • list_voice_models

    Use this when the user wants to convert audio and you need to select one of their private NiceVois-trained or uploaded RVC voices. Do not ask for a model ID before calling this tool.

  • create_voice_model_import

    Use this when the user wants to convert with an existing private RVC .pth file or complete model ZIP instead of a voice trained in their NiceVois library. Returns a one-time PUT upload instruction. After uploading, call list_voice_models to select the imported voice.

  • create_voice_conversion

    Use this when the user has selected a private voice model and wants to convert one vocal recording. Returns a private upload instruction. Upload only the source vocal, then call get_voice_conversion with the same conversion ID. Creating it counts one of the account's conversions

  • get_voice_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 reque

  • download_voice_conversion_output

    Use after get_voice_conversion says the job is complete and the user wants the cleaned or standard output. Downloads are free; the conversion was counted once when it started. If the exact file was downloaded before, ask before retrying and then set confirmRepeat true.

  • list_free_audio_tools

    Use this to see NiceVois's free audio tools, which need no account, no API key and no sign-up: split a song into vocals and instrumental (vocal remover, acapella, karaoke instrumental), split lead vocals from backing vocals, remove background noise, remove reverb or echo, and enh

  • create_free_audio_job

    Split stems, isolate vocals, split lead from backing vocals, remove noise or reverb, or enhance a vocal. No account, API key or sign-up needed: one free use of each tool per network, of a file up to five minutes, as on the website. A connected account runs it on that account's pl

  • get_free_audio_job

    Use this after create_free_audio_job and the upload, no more than every 10 seconds, until the job is completed or failed. When it completes, it lists every output file (for example lead vocal, backing vocals, instrumental) with a download link.

  • create_audio_job

    Every NiceVois audio tool. With no account: split_stems, split_lead_backing, remove_noise, remove_reverb and enhance_vocal (one free use of each per network, up to five minutes) and convert_format (free). With a connected account every tool runs on that account's plan (a subscrib

  • get_audio_job

    Use after create_audio_job and the upload, until the job is completed or failed. When complete it lists each output; call get_audio_download for the ones the user wants.

  • get_audio_download

    Returns a short-lived link to one output of a completed audio job. Download it or give it to the user straight away.

Common questions

Is NiceVois safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 13 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, arr-mcp
