| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `redo_stem`

- 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:

```untrusted-server-text
Make one stem of a finished song again (new drums, say), with the other four exactly as they are; the mix becomes the new part with the rest. Counts as one song. Takes about a minute; the player shows it. undo_stem puts the old part back.
```

### `undo_stem`

- The description's first verb is "put": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Put a song's version back to how it was before its last redo_stem: the old part plays again, and the mix with it. Costs nothing. Only the last redo can be undone.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_song`

- The name "create_song" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Make an original instrumental song from a description: genre, mood, instruments, tempo, what it's for. Returns it queued; the player in the chat shows it rendering and plays it when it's done (about a minute), with MP3 and WAV downloads and its five stems (drums, bass, guitar, keys, other) as FLAC. Where there's no player, get_song gives those links once it's done. No artist names: describe the sound instead. Royalty-free, for commercial games and videos.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_song`

- The name "get_song" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Where a song made with create_song stands: its place in line, or, once done, each version's MP3 and WAV links and its five stems' FLAC links (a few seconds after the mix), and any part being made again with redo_stem.
```

### `get_songs_left`

- The name "get_songs_left" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How many songs the person has made this month and how many they can make (no limit on some accounts), and when the count starts again.
```

### `list_songs`

- The name "list_songs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The songs on the person's Daydream account, newest first: each one's id, words, length, tempo and how many versions. Use get_song with an id to play one.
```
