🚀 Quick Start

Prerequisites (local installation)

Python 3.8+ - Download Python
FFmpeg - Install FFmpeg
uv (recommended) - Install uv or use pip

Installation

Option 1: Using Smithery (Easiest) ⭐

The simplest way to get started is through the Smithery MCP registry:

Clipboard-20250524-191433-493

Option 2: Using uv (Recommended for Development)

# Install uv if you haven't already
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone the repository
git clone https://github.com/misbahsy/video-audio-mcp.git
cd video-audio-mcp

# Install dependencies with uv
uv sync

# Verify FFmpeg installation
ffmpeg -version

Running the Server

# With uv (recommended)
uv run server.py

# Or with traditional python
python server.py

# Or with specific transport
python -c "from server import mcp; mcp.run(transport='stdio')"

🔧 Client Configuration

Claude Desktop (Recommended Configuration)

Add to your claude_desktop_config.json:

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

{
  "mcpServers": {
    "VideoAudioServer": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/your/video-audio-mcp",
        "run",
        "server.py"
      ]
    }
  }
}

Alternative (using Python directly):

{
  "mcpServers": {
    "VideoAudioServer": {
      "command": "python",
      "args": ["/path/to/video-audio-mcp/server.py"]
    }
  }
}

Cursor IDE (Recommended Configuration)

Open Cursor Settings: File → Preferences → Cursor Settings → MCP
Click "Add New Server"
Configure:
- Name: VideoAudioServer
- Type: command
- Command: uv --directory /path/to/your/video-audio-mcp run server.py

Alternative configuration:

Command: /path/to/python /path/to/video-audio-mcp/server.py

Windsurf

Add to your MCP configuration:

{
  "mcpServers": {
    "VideoAudioServer": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/your/video-audio-mcp",
        "run",
        "server.py"
      ],
      "env": {}
    }
  }
}

Why Use uv?

The uv command is recommended because it:

Automatically manages dependencies without needing to activate virtual environments
Faster installation and dependency resolution
Better isolation - each project gets its own environment automatically
More reliable - handles Python version and dependency conflicts better
Modern tooling - the future of Python package management

Using NPX (Alternative)

For easier distribution, you can also run via npx if packaged:

{
  "mcpServers": {
    "VideoAudioServer": {
      "command": "npx",
      "args": ["-y", "video-audio-mcp-server"]
    }
  }
}

    # Setup
    input_file = "path/to/test/file.mp4"
    output_file = os.path.join(OUTPUT_DIR, "test_output.mp4")
    
    # Execute
    result = your_new_function(input_file, output_file, parameters)
    
    # Validate
    assert "success" in result.lower()
    assert os.path.exists(output_file)
    
    # Optional: Validate output properties
    duration = get_media_duration(output_file)
    assert duration > 0

Continuous Integration

The test suite is designed to work in CI/CD environments:

# Example GitHub Actions workflow
- name: Install FFmpeg
  run: sudo apt-get install ffmpeg

- name: Install dependencies
  run: pip install -r requirements.txt pytest

- name: Run tests
  run: pytest tests/ -v

Performance Testing

Some tests include performance validation:

Duration Checks: Verify output video lengths match expectations
