adjust_mixChanges 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.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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).

set_stem_labelsSets what is on each stem from what the person says about their files (stem ids and file names come from get_song_status).No findings
Why it is in this group
- The name "set_stem_labels" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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.

Why it is in this group

- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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. The studio shows the progress and plays the new master, which replaces an earlier master made in the chat (downloaded ones stay).

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
