Nodaro MCP music tools — generate_music and the Suno tools for songs, covers, stems and extensions

Create songs and instrumentals with Suno and other music models, then extend, cover, mash up, edit, split and convert them with Nodaro's MCP music tools.

The music tools let an assistant make and edit music in Nodaro. generate_music creates a track from a prompt, or follows a reference track with MiniMax Music. The suno_ tools use Suno's full feature set: songs with your own lyrics, covers, extensions, mashups, section replacement, stems, WAV files and music videos. Every tool needs the workflows:execute permission and returns a job id.

The tools that edit a Suno song need the Nodaro job id of a song made with Suno, passed as audio_asset_id. The Suno ids they need are looked up on the server.

`generate_music`

Creates a music track from a prompt. With a Suno model, the default, it works like the Suno Create Music node. With minimax, it runs MiniMax Music like the Generate Music node, and it needs a reference track.

Permission: workflows:execute. Credits: 33 with a Suno model, 198 with MiniMax.

Parameter	Type	Notes
`prompt`	string	The music you want, up to 2,000 characters. Required unless a preset supplies it.
`model`	string	`suno-v6` (default, rich detail and natural vocals), `suno-v6_wild` (bolder, less predictable), `suno-v6_mini` (faster), `suno-v5_5`, `suno-v5`, `suno`, or `minimax` (MiniMax Music), which follows a reference track. `suno-v5-5` is also accepted for `suno-v5_5`.
`reference_audio_url`	string	With `minimax`: the public URL of the song, voice or instrumental that MiniMax Music follows.
`reference_audio_asset_id`	string	With `minimax`: the Nodaro job id of an audio result to follow. It is used when `reference_audio_url` is not set.
`lyrics`	string	The exact words to sing, up to 2,000 characters, with section tags such as `[Verse]` and `[Chorus]` on their own lines. Lyrics switch Suno to custom mode, where they are sung as written. Without lyrics, the model writes its own.
`title`	string	The song title, up to 80 characters. Custom mode needs one; without it, the title is "Untitled".
`instrumental`	boolean	Music without vocals.
`genre`, `mood`	string	The genre and the mood.
`duration`	number	The length of a short track, up to 30 seconds. Without it, the model chooses the length. For a set length of up to 360 seconds, use `suno_generate`. With Suno, `duration` works only in custom mode on a V6 model, and a length under 10 seconds is raised to 10. On an `instrumental` track, a `title` or a `duration` turns on custom mode by itself. MiniMax Music ignores it.
`presetId`	string	A preset such as Lo-fi Study, Cinematic Trailer or EDM Drop.

With minimax, pass reference_audio_url or reference_audio_asset_id. Without a reference, the tool returns an error that asks for one, and no job starts. The Suno models need no reference and ignore both parameters.

Returns: a job id.

`suno_generate`

Creates an original song with Suno, with every Suno control. It works like the Suno Create Music node. The job output holds the Suno ids that the other suno_ tools use.

It works like the Suno Separate node.

Permission: workflows:execute. Credits: 44 with separate_vocal, 143 with split_stem, 88 with split_stem_advanced. A run that falls back to Demucs is charged the Audio Separation price instead.

Parameter	Type	Notes

Frequently asked questions

What is the difference between generate_music and suno_generate?

generate_music is the simple tool for a track from a prompt, with Suno V6 by default. Its minimax model, MiniMax Music, follows a reference track that you pass as reference_audio_url or reference_audio_asset_id. suno_generate exposes Suno's own controls, such as custom mode with your lyrics and style, weirdness, style weight and negative styles.

How much does a Suno song cost?

33 credits per generation, on every Suno version. Lyrics, style boost, WAV conversion and music videos cost 11 credits, and replacing a section costs 22.

Can I split any song into stems?

Yes. suno_separate_stems takes any audio, a Suno song, an upload or a link, up to 20 MB. Suno refuses commercially released recordings. For those, use separate_audio, which runs Demucs, or set fallback_to_demucs.

How do I make a song with my own lyrics?

Call suno_generate with custom_mode set to true, your lyrics with section tags such as [Verse] and [Chorus], and a style. With generate_music, passing lyrics switches to the same custom mode.
