AivisSpeech MCP Server

This is an implementation of the Model Context Protocol (MCP) server for AivisSpeech. This server works with the AivisSpeech Engine to provide an interface for speech synthesis. Through the MCP protocol, it becomes easy to use AivisSpeech's speech synthesis function from applications such as AI assistants.

overview

AivisSpeech MCP Server provides the following features:

MCP protocol compliant API endpoints
High-quality voice synthesis in cooperation with AivisSpeech Engine
Type-safe design with TypeScript
Easy to configure and highly scalable architecture

Prerequisites

Node.js 18.x or higher
npm 9.x or higher
AivisSpeech Engine (requires separate installation)

install

# リポジトリをクローン
git clone https://github.com/kentaro/aivis-speech-mcp.git
cd aivis-speech-mcp

# 依存関係のインストール
npm install

# ビルド
npm run build

# 環境変数の設定
cp .env.sample .env
# .envファイルを編集して、必要な設定を行ってください

# Cursor MCPの設定
cp .cursor/mcp.json.sample .cursor/mcp.json
# mcp.jsonファイル内の"/path/to/aivis-speech-mcp/dist/index.js"を
# 実際のプロジェクトパスに書き換えてください
# 例: "C:/Users/username/path/to/aivis-speech-mcp/dist/index.js"

Environment settings

In your .env file, set the following:

# AivisSpeech API Configuration
AIVIS_SPEECH_API_URL=http://localhost:10101  # AivisSpeech EngineのAPIエンドポイント

# Speaker Configuration
AIVIS_SPEECH_SPEAKER_ID=888753760  # デフォルトのスピーカーID

Cursor MCP Settings

In .cursor/mcp.json file, configure the following:

{
  "mcpServers": {
    "AivisSpeech-MCP": {
      "command": "node",
      "args": ["/path/to/aivis-speech-mcp/dist/index.js"]
    }
  }
}

Replace /path/to/aivis-speech-mcp/dist/index.js with the path to your project. For Windows, escape the backslashes or use forward slashes. For example: "C:/Users/username/path/to/aivis-speech-mcp/dist/index.js"

How to use

Development Mode

During development you can start the server with hot reloading with the following command:

npm run dev

Build

To build for production run the following command:

npm run build

Production Mode

npm start

test

To run the tests use the following command:

npm test

architecture

AivisSpeech MCP Server consists of the following components:

MCP Service : Provides a server that complies with the Model Context Protocol and processes requests from clients.
AivisSpeech Service : Communicates with the AivisSpeech Engine API and performs speech synthesis.

API Specifications

We provide API endpoints that comply with the MCP protocol. The main features are as follows:

Speech synthesis (generating speech from text)
Get speaker information
Audio style settings

For detailed API specifications, please refer to AivisSpeech Engine API Specification .

Integration with MCP protocol

This server implements the Model Context Protocol (MCP) and can be used seamlessly with applications such as AI assistants. For more information about the MCP protocol, see the official MCP documentation .

troubleshooting

Common issues and solutions:

Can't connect to AivisSpeech Engine : Check if AIVIS_SPEECH_API_URL in .env file is set correctly
No sound : Check your system's audio settings and make sure the correct audio device is selected
Speaker ID not found : Make sure AivisSpeech Engine is running properly and check for available speaker IDs.
