## Changes things (1)

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

### `text_to_speech`

- The description's first verb is "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Convert text to speech with YarnGPT. Pass text (required, max 2000 characters) and voice (required). response_format defaults to mp3 (mp3, wav, opus, or flac). Use list_voices to discover voices. API key comes from global_variables.
```

## Only reads (1)

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

### `list_voices`

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

Description, as the server wrote it:

```untrusted-server-text
List all available YarnGPT voices with names and descriptions. Use before text_to_speech when the user asks which voices exist or which voice to pick. Voices: Idera, Emma, Zainab, Osagie, Wura, Jude, Chinenye, Tayo, Regina, Femi, Adaora, Umar, Mary, Nonso, Remi, Adam.
