Description

This MCP server receives instructions from Claude Code and generates speech audio via the VOICEVOX Engine running in Docker. It plays the synthesized voice locally using ffplay, enabling developers to receive auditory feedback in natural Japanese. The server can automatically start the VOICEVOX Engine Docker container if it is not running, simplifying setup and usage.
