- Audio input/output devices on your system

## Installation

### Installing via Smithery

To install Audio Interface Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@GongRzhe/Audio-MCP-Server):

```bash
npx -y @smithery/cli install @GongRzhe/Audio-MCP-Server --client claude
```

### Manual Installation
1. Clone this repository or download the files to your computer:

```bash
git clone https://github.com/GongRzhe/Audio-MCP-Server.git
cd Audio-MCP-Server
```

2. Create a virtual environment and install dependencies:

```bash
# Windows
python -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt

# macOS/Linux
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
```

3. Or use the included setup script to automate installation:

```bash
python setup_mcp.py
```

## Configuration

### Claude Desktop Configuration

To use this server with Claude Desktop, add the following to your Claude Desktop configuration file:

- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "audio-interface": {
      "command": "/path/to/your/.venv/bin/python",
      "args": [
        "/path/to/your/audio_server.py"
      ],
      "env": {
        "PYTHONPATH": "/path/to/your/audio-mcp-server"
      }
    }
  }
}
```

Replace the paths with the actual paths on your system. The setup script will generate this configuration for you.
