Implementation Reference
- src/voicevox.ts:15-31 (handler)The getVoices() method that implements the core logic for list_voices. It fetches speakers from the VOICEVOX API, iterates through them and their styles, and returns an array of Voice objects with character, name, and id.
async getVoices(): Promise<Voice[]> { const response = await fetch(`${this.baseUrl}/speakers`); const speakers = await response.json() as any[]; const voices: Voice[] = []; for (const speaker of speakers) { for (const style of speaker.styles) { voices.push({ character: speaker.name, name: style.name, id: style.id, }); } } return voices; } - src/index.ts:191-201 (handler)The case handler for list_voices tool in the main switch statement. It calls voicevox.getVoices() and returns the result as JSON-formatted text content.
