No check matched anything in these tool definitions.


## Changes things (8)

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

### `build_cart`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Turn chosen songs and licenses into one link that opens the person's Starchild cart with everything already added. Checkout happens on starchild.music. Use license ids from license_options (e.g. song-only, song-instrumental, royalty-free, exclusive-license).
```

### `change_style`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Hear a Starchild song in a different production style (for example Country, Acoustic Indie, Electro Rock, Latin Salsa, Piano Ballad Orchestral). Returns a link that opens the song on starchild.music set to that style, with the original vocal. Lists the available styles if the requested one isn't made for this song.
```

### `check_transform`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
For a connected Starchild member: progress and listening links for a transform started with transform_song.
```

### `how_to_sell_songs`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
For songwriters and catalog owners: how to list original songs on Starchild, what it costs, how licensing earnings are paid, and who keeps the rights.
```

### `license_options`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
What licensing a Starchild song costs. With a song, returns exactly which licenses and add-ons that song offers and their prices. Without one, returns the standard price list. All prices are one-time, in US dollars.
```

### `play_song`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Play a Starchild song: shows an in-chat player with the original recording and every production style made for it (same vocal; switch styles mid-song), plus starchild.music links for each style.
```

### `transform_song`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
For a connected Starchild member: render NEW versions of a catalog song in chosen production styles, keeping the original vocal, using their credits (2 per style, 3 per style for songs over 3:30). Optional creative direction in plain words. Takes a few minutes; returns a job id for check_transform. Results also save to the member's Gen library on starchild.music. Use change_style first for styles that already exist (free).
```

### `verify_certificate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check whether a Starchild license certificate number (format SC-2026-123456) is genuine, and which song and license it covers.
```

## Only reads (3)

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

### `account_status`

- The name "account_status" says "status": a word for reading.

Description, as the server wrote it:

```

### `get_song`

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

Description, as the server wrote it:

```untrusted-server-text
Full details for one Starchild song: writers, genres, moods, key, tempo, every production style, sounds-like, similar songs, and which licenses are available. Accepts the song id, its starchild.music link, or its exact title.
```

### `search_songs`

- The name "search_songs" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search Starchild's catalog of original songs by meaning: describe the song in plain words (e.g. 'uplifting country ballad about starting over, female vocal'). Optional filters narrow by genre, mood, vocal or tempo. Shows an in-chat browser where every result plays, in every production style, with more results on request (use offset).
```
