Video Editor MCP Server

A powerful video editing MCP server that leverages FFmpeg to perform video editing operations through natural language commands.

Components

Tools

The server implements one main tool:

• `execute_ffmpeg`: Executes FFmpeg commands with progress tracking
  • Takes a command string as input
  • Validates and executes FFmpeg operations
  • Reports real-time progress during processing
  • Handles errors and provides detailed feedback
  • Supports all FFmpeg operations including:
    • Trimming/cutting
    • Merging videos
    • Converting formats
    • Adjusting speed
    • Adding audio tracks
    • Extracting audio
    • Adding subtitles
    • Basic filters (brightness, contrast, etc.)

Configuration

Prerequisites

1. FFmpeg must be installed and accessible in your system PATH

2. Python 3.9 or higher

3. Required Python packages:

mcp
   httpx

Installation

1. Install FFmpeg if not already installed:

# On macOS with Homebrew
   brew install ffmpeg

   # On Windows with Chocolatey
   choco install ffmpeg

   # On Ubuntu/Debian
   sudo apt install ffmpeg

2. Install the video editor package:

uv add video-editor

Claude Desktop Integration

Configure in your Claude Desktop config file:

On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`

On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

{
  "mcpServers": {
    "video-editor": {
      "command": "uv",
      "args": ["run", "video-editor"]
    }
  }
}

Development

Building and Publishing

1. Sync dependencies:

uv sync

2. Build package:

uv build

3. Publish to PyPI:

uv publish

Note: Set PyPI credentials via:

• Token: `--token` or `UV_PUBLISH_TOKEN`
• Or username/password: `--username`/`UV_PUBLISH_USERNAME` and `--password`/`UV_PUBLISH_PASSWORD`

Debugging

For the best debugging experience, use the MCP Inspector:

npx @modelcontextprotocol/inspector uv --directory /path/to/video_editor run video-editor

Example Usage

Once connected to Claude Desktop, you can make natural language requests like:

1. "Trim video.mp4 from 1:30 to 2:45"

2. "Convert input.mp4 to WebM format"

3. "Speed up video.mp4 by 2x"

4. "Merge video1.mp4 and video2.mp4"

5. "Extract audio from video.mp4"

6. "Add subtitles.srt to video.mp4"

The server will:

1. Parse your request

2. Generate the appropriate FFmpeg command

3. Execute it with progress tracking

4. Provide feedback on completion

Error Handling

The server includes robust error handling for:

• Invalid input files
• Malformed FFmpeg commands
• Runtime execution errors
• Progress tracking issues

All errors are reported back to the client with detailed messages for debugging.

Security Considerations

• Only processes files in explicitly allowed directories
• Validates FFmpeg commands before execution
• Sanitizes all input parameters
• Reports detailed error messages for security-related issues
