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
