• WebSocket Support: Real-time bidirectional communication
• Context Management: Maintain conversation context for improved transcription accuracy
• Multiple Audio Formats: Support for various audio formats with automatic conversion
• Language Detection: Automatic language detection and confidence scoring
• Event Detection: Identify speech and non-speech audio events

Installation

1. Clone the repository:

git clone https://github.com/aromanstatue/MCP-Elevenlab-Scribe-ASR.git
cd MCP-Elevenlab-Scribe-ASR

2. Create and activate a virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

pip install -e .

4. Create a .env file with your ElevenLabs API key:

ELEVENLABS_API_KEY=your-api-key-here

Usage

Starting the Server

python -m elevenlabs_scribe_mcp_server.main

The server will start on port 8000 by default (or the next available port).

Using the Example Client

1. File Transcription:

python examples/client_example.py --file path/to/audio.wav

2. Microphone Transcription:

python examples/client_example.py --mic

API Endpoints

1. REST API:

• POST /transcribe: Upload an audio file for transcription
• GET /health: Health check endpoint

2. WebSocket API:

• ws://localhost:8000/ws/transcribe: Real-time audio transcription

MCP Protocol

The server implements the Model Control Protocol (MCP) with the following message types:

1. INIT: Initialize a new transcription session
2. START: Begin audio streaming
3. AUDIO: Send audio data
4. TRANSCRIPTION: Receive transcription results
5. ERROR: Error messages
6. STOP: End audio streaming
7. DONE: Complete session
