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.

Разработка переехала в theYahia/YaAll — сборку, где весь яндексовский слой лежит в одном месте: свои MCP-серверы, скиллы Claude Code и материалы официальных наборов Яндекса.
Актуальная версия того, что лежало здесь:
mcp/yandex-speechkit-mcp/Пакет в npm прежний —
@theyahia/yandex-speechkit-mcp, ставится и работает как раньше. Здесь больше ничего не обновляется. Задачи и pull request'ы — в YaAll.Archived — development moved to theYahia/YaAll, a single repository bundling the whole Yandex stack. The current version of this package now lives at
mcp/yandex-speechkit-mcp/. The npm package@theyahia/yandex-speechkit-mcpis unchanged. Please open issues and pull requests there.
Этот сервер входит в сборку theYahia/YaAll — весь яндексовский слой в одном репозитории: десять MCP-серверов, скиллы Claude Code под SEO и валидацию спроса, плюс материалы официальных серверов Яндекса. Здесь он живёт отдельно, там — рядом с остальными:
mcp/yandex-speechkit-mcp/Part of theYahia/YaAll — the whole Yandex stack in one repo.
