Ffmpeg Mcp

FFmpeg MCP Server

A Model Context Protocol (MCP) server that provides video and audio manipulation tools powered by FFmpeg. This server enables AI assistants to perform media operations like cutting videos, converting formats, removing silence, and more.

Features

• Self-contained - Includes bundled FFmpeg binary via ffmpeg-static, no system installation required
• Format conversion - Convert between audio/video formats (mp4, mp3, wav, mov, etc.)
• Video editing - Cut segments, concatenate multiple videos, convert images to video
• Audio processing - Detect and remove silent segments automatically
• Local by default - Inputs and outputs stay inside a configured workspace

Available Tools

Installation

From npm (recommended)

npm install -g ffmpeg-mcp-server

From source

git clone https://github.com/PedroMarianoAlmeida/ffmpeg-mcpcd ffmpeg-mcpnpm installnpm run build

Configuration

Workspace and safety

Every input and output must be inside FFMPEG_MCP_WORKSPACE. If it is unset, the server's current working directory is used. The server resolves symlinks before reading and rejects URL schemes, traversal outside the workspace, and symlink outputs. Create output directories before running a tool.

ffmpeg_raw is deliberately restricted. It accepts local -i inputs, one final local output path, and a small set of codec and timing options. It does not accept filters, forced formats, or arbitrary FFmpeg flags because those options can load extra files or use network protocols.

For example, set a dedicated media directory in your MCP configuration:

{  "mcpServers": {    "ffmpeg": {      "command": "npx",      "args": ["ffmpeg-mcp-server"],      "env": {        "FFMPEG_MCP_WORKSPACE": "/absolute/path/to/media-workspace"      }    }  }}

Claude Desktop

Add to your claude_desktop_config.json:

{  "mcpServers": {    "ffmpeg": {      "command": "npx",      "args": ["ffmpeg-mcp-server"]    }  }}

Claude Code

Add to your Claude Code MCP settings:

{  "mcpServers": {    "ffmpeg": {      "command": "npx",      "args": ["ffmpeg-mcp-server"]    }  }}

Usage Examples

Cut a video segment

"Cut the first 30 seconds from video.mp4"→ Uses cut_video tool

Convert formats

"Convert video.mov to mp4""Extract audio from video.mp4 as mp3"→ Uses convert tool

Remove silence

"Remove silent parts from my podcast recording"→ Uses remove_silence tool (detects silence > 2s at -30dB by default)

Restricted raw operations

"Convert input.mp4 to output.mp4 using libx264"→ Uses ffmpeg_raw with local paths and supported codec options
