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.)

Development

Building and Publishing

1. Sync dependencies:

   Copy

   uv sync

2. Build package:

   Copy

   uv build

3. Publish to PyPI:

   Copy

   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

Configuration

Prerequisites

1. FFmpeg must be installed and accessible in your system PATH
2. Python 3.9 or higher
3. Required Python packages:
   Copy

   mcp
