What is Voicevox MCP Server?

Voicevox MCP Server is a Model Context Protocol (MCP) compliant server that uses the Voicevox Engine for speech synthesis. It converts text into audio and plays the result, providing endpoints callable from AI tools such as Cursor and Cline.

How to use Voicevox MCP Server?

Install dependencies with uv sync, start the Voicevox Engine via Docker, then configure the server in your MCP client (e.g., Cline, Roo code) using the provided JSON settings. The server runs as a stdio-based MCP tool and can be invoked with synthesizeAndPlay(message="..."). Optional arguments include --host, --port, and --speaker (default speaker ID is 3).

FAQ from Voicevox MCP Server

What are the prerequisites?

Python 3.10 or higher is required, along with a running Voicevox Engine (local or remote). The recommended way to run the engine is via Docker (CPU or GPU image).

How does it handle English text?

By default, English letters are spoken one character at a time. Workarounds include converting the text to katakana before input or using a custom dictionary (custom dictionary creation is not yet implemented).

Which transport protocol does it use?

It uses JSON‑RPC over stdio, which is the standard MCP transport.

Is Claude Desktop supported?

Claude Desktop has not been tested yet.

What is the default speaker ID?

The default speaker ID is 3. It can be changed with the --speaker option; a list of available speaker IDs is referenced from the Voicevox VVM repository.
