Summary
Connects Claude to Yandex SpeechKit for Russian and multilingual speech operations. You get five tools: recognize and synthesize for direct STT/TTS with base64 audio, list_voices to browse available speakers with language filters, plus two convenience wrappers (skill_transcribe and skill_synthesize) that handle common cases with smart defaults. Requires a Yandex Cloud API key and folder ID. The skill tools auto-detect language from voice selection and return clean output without extra ceremony. Part of a broader Russian API MCP series. Useful if you're building voice interfaces or need programmatic access to Yandex's speech models without leaving your Claude workflow.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
