The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
adjust_mix Change the mix ~173
Changes a song mixed from stems the way the person asks after listening: a stem louder or quieter, muted or back in, more or less reverb, or placed left, center or right. One call takes all the changes for a song. Bandmixr then makes the mix and the master again with the changes (about as long as the first mix); the studio shows the progress and plays the new version, which replaces the earlier version made in the chat (downloaded versions and mixes made on the website stay). Stem ids, file names and the current settings come from get_song_status.
| Name | Type | Req | Description |
|---|---|---|---|
| changes | array | yes | – |
| preset | string | – | Mastering style for the new master; the current one if not given. |
| songId | string | yes | The song id from list_songs or create_song. |
No output schema declared.
No examples provided.
check_mix Check a mix ~177
Opens the Bandmixr Mix Analyzer in the chat. It checks a mix or master in the browser (the file is not uploaded): loudness (LUFS), true peak, clipping, stereo image and tonal balance, with a verdict for each and a 30-second mastered preview.

create_song Create a song ~263
Creates a new song in Bandmixr for mixing stems and opens the studio with its upload box. The genre and the mastering style are the ones the person names (other and streaming when they name none). Mixing and mastering are part of it: they start by themselves once the stems are uploaded and the person has confirmed the labels in the studio.
| Name | Type | Req | Description |
|---|---|---|---|
| genre | string | – | Genre of the song. rock_indie = rock / indie; pop = pop; acoustic = acoustic, singer-songwriter; hip_hop_grime = hip hop, rap, trap, grime; electronic = electronic, EDM, house, techno; reggae_dub = r… |
| mix | boolean | – | false = upload now, mix later (default true: mix once the labels are confirmed). |
| preset | string | – | Mastering style. streaming = optimized for Spotify and Apple Music; optimal = balanced ("Standard"); loud = maximum punch and loudness. |
| title | string | – | The song's name, as the person calls it. |
No output schema declared.

get_account Show my Bandmixr account ~42
Shows the connected Bandmixr account's plan and its limits (stems per song, song length, storage). Needs the person to connect their Bandmixr account.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_analyzer_session Get studio session ~61
Returns a 30-minute ticket and the address of the Bandmixr preview service, which the studio in the chat uses for the 30-second mastered preview. The studio calls this tool on its own; the assistant does not need to call it directly.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_song_session Start a studio session for a song ~89
Returns a 15-minute ticket for one of the person's songs, which the studio in the chat uses to upload stems, show the label check and the progress, and play the original, the mix and the master. The studio calls this tool on its own; the assistant does not need to call it directly.
| Name | Type | Req | Description |
|---|---|---|---|
| songId | string | yes | The song id from list_songs or create_song. |
No output schema declared.

master_song Master a song ~218
Opens the Bandmixr studio in the chat to master or enhance a finished song (a stereo mix). The song is checked in the browser for loudness, peaks, stereo image and tonal balance, and a 30-second mastered preview plays next to the original. Mastering the full song needs a Bandmixr account.
| Name | Type | Req | Description |
|---|---|---|---|
| genre | string | – | Genre of the song. rock_indie = rock / indie; pop = pop; acoustic = acoustic, singer-songwriter; hip_hop_grime = hip hop, rap, trap, grime; electronic = electronic, EDM, house, techno; reggae_dub = r… |

No output schema declared.
No examples provided.
mix_and_master Mix and master a song ~201
Mixes an existing song's stems and masters the mix in one go (draft, final mix, master), for example to mix it again with another genre or mastering style; a song made with create_song is already set up for this. It waits for the uploads, the analysis and the person's "Labels are correct" in the studio, then starts by itself. The mastering style is the one the person names (streaming when they name none). The studio shows the progress and plays the result; a new mix replaces the earlier version made in the chat (downloaded versions and mixes made on the website stay).
| Name | Type | Req | Description |
|---|---|---|---|
| master | boolean | – | false = mix only, without a master (default true). |
| preset | string | – | Mastering style. streaming = optimized for Spotify and Apple Music; optimal = balanced ("Standard"); loud = maximum punch and loudness. |

open_song_studio Open a song in the studio ~84

|---|---|---|---|
| songId | string | yes | The song id from list_songs or create_song. |
No output schema declared.
No examples provided.
prepare_full_master Prepare mastering of the full song ~188
Creates a new song named after the file the person checked in the studio and returns a short-lived ticket for uploading it, so the studio can upload and master the full song. The studio calls this tool when the person chooses to master the full song; the assistant does not need to call it directly.
| Name | Type | Req | Description |
|---|---|---|---|
| genre | string | – | Genre of the song. rock_indie = rock / indie; pop = pop; acoustic = acoustic, singer-songwriter; hip_hop_grime = hip hop, rap, trap, grime; electronic = electronic, EDM, house, techno; reggae_dub = r… |
| title | string | yes | – |
No output schema declared.
No examples provided.
set_stem_labels Set stem labels ~87
Sets what is on each stem from what the person says about their files (stem ids and file names come from get_song_status). It does not confirm the labels: the person still confirms them with "Labels are correct" in the studio before anything is mixed.
| Name | Type | Req | Description |
|---|---|---|---|
| labels | array | yes | – |
| songId | string | yes | The song id from list_songs or create_song. |
No output schema declared.

start_mastering Master a mixed song ~125
Masters the song's finished mix, or masters it again in another style (for example "louder": loud). The song needs a finished mix, from mix_and_master or an uploaded mix.
