FFmpeg Video Processor MCP server

This MCP FFmpeg Video Processor is a Node.js server that leverages FFmpeg to manipulate video files. It provides APIs for resizing videos to different resolutions (360p, 480p, 720p, 1080p) and extracting audio from videos in various formats (MP3, AAC, WAV, OGG).

Before running this application, you need to have the following installed:

1. Node.js (v14 or higher)
2. FFmpeg - This is required for video processing

Installing FFmpeg

On macOS:

brew install ffmpeg

On Ubuntu/Debian:

sudo apt update
sudo apt install ffmpeg

On Windows:

1. Download FFmpeg from the official website
2. Extract the files to a folder (e.g., C:\ffmpeg)
3. Add the bin folder to your PATH environment variable

Integration with Claude Desktop

Configuring Claude Desktop

To add this server to Claude Desktop, update your Claude Desktop configuration file:

1. Locate your Claude Desktop config file:

   • macOS: ~/.config/claude-desktop/config.json or ~/Library/Application Support/Claude Desktop/config.json
   • Windows: %APPDATA%\Claude Desktop\config.json
   • Linux: ~/.config/claude-desktop/config.json

2. Add the FFmpeg MCP server to the mcpServers section:

{
    "mcpServers": {
        "ffmpeg": {
            "command": "npx",
            "args": [
                "--yes",
                "/absolute/path/to/mcp-ffmpeg"
            ]
        }
    }
}

If you've published the package to npm:

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

3. Restart Claude Desktop for the changes to take effect.

Integration with Cursor

To install mcp-ffmpeg for Cursor:

1. Go to Settings -> Cursor Settings -> Features -> MCP Servers -> + Add
2. Select Type: command and paste the following:

npx -y @smithery/cli@latest run @bitscorp/mcp-ffmpeg

Using the Server

Once configured, you can use the server through Claude Desktop with natural language requests like:

Using the ffmpeg MCP server, please resize the video at /path/to/video.mp4 to 720p resolution.

Notes on Server Operation

• Uploaded videos are stored temporarily in the uploads directory
• Processed videos and audio files are stored in the output directory
• The server has a file size limit of 500MB for uploads

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
