MCP-FFmpeg

FFmpeg video & audio editing tools via Model Context Protocol (MCP)

Python 3.10+ License: MIT MCP Compatible FFmpeg

Give your AI assistant the power to edit video and audio — trim, transcode, overlay, compose, and more.

Quick Start · Tools · Configuration · Architecture


Why MCP-FFmpeg?

AI assistants are great at understanding what you want to do with media files, but they can't actually do it — until now. MCP-FFmpeg bridges the gap by exposing 30+ FFmpeg operations as MCP tools that any compatible AI assistant can call directly.

You: "Trim this video from 00:30 to 02:00, add a fade-in, and convert to 720p"
AI:  Calls trim_video → add_basic_transitions → set_video_resolution → Done!

Quick Start

Prerequisites

Requirement

Version

Purpose

Python

3.10+

Runtime

FFmpeg

Any recent

Media processing engine

uv

Latest

Python package manager (recommended)

Install & Run

git clone https://github.com/kevinten-ai/mcp-ffmpeg.git
cd mcp-ffmpeg
uv sync
uv run python main.py

MCP Client Configuration

Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "ffmpeg-tools": {
      "command": "uv",
      "args": ["--directory", "/path/to/mcp-ffmpeg", "run", "python", "main.py"]
    }
  }
}

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "ffmpeg-tools": {
      "command": "uv",
      "args": ["--directory", "/path/to/mcp-ffmpeg", "run", "python", "main.py"]
    }
  }
}

Cursor / Other MCP Clients

Use the same server configuration — any client that supports MCP's stdio transport will work.
