🗄 Репозиторий заархивирован

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-mcp is 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.
