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

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:

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
