Voiceroid Daemon Mcp

Voiceroid Daemon Mcp is an MCP server that connects Claude Desktop and other Model Context Protocol clients to VOICEROID2 via the voiceroid_daemon service. Software developers, digital content creators, and Japanese language enthusiasts use it to trigger speech synthesis directly through conversational AI prompts. The server enables an AI agent to verify daemon network connectivity, convert standard Japanese text into phonetic kana representations, and generate spoken audio output with customized voice settings. Users can configure sound parameters such as volume, playback speed, pitch, and emphasis, allowing precise adjustment over how synthetic speech sounds. Operating across macOS, Windows, and Linux, the server plays speech audio locally through the host system using native media tools such as afplay, PowerShell SoundPlayer, or aplay. By bridging large language models to local VOICEROID2 installations, it facilitates real-time spoken responses, accessibility reading tools, and automated media production workflows without requiring manual clipboard copying or switching between multiple applications.
