AI Video Generator MCP Server

This MCP (Model Context Protocol) server provides tools to generate videos from text prompts and images using AI image generation models.

Compatible Models

Luma Ray2 Flash - Luma's cutting edge image to video conversion model
Kling v1.6 Pro - Kling's high quality image to video conversion model

function

Video generation from text prompts
Video generation with start and/or end images
Control video parameters (aspect ratio, resolution, duration, loop)
Check the generation status
Choosing which AI model to use

install

Clone this repository
Install the dependencies:
npm install
Create a .env file and set your FAL.AI API key:
FAL_KEY=your_fal_key_here
You can get the API key from FAL.AI

Building the Server

npm run build

Running the Server

You can run the server directly:

npm start

Integration with Claude Desktop

To use this server with Claude Desktop, add the following to your claude_desktop_config.json file:

{
  "mcpServers": {
    "video-generator": {
      "command": "node",
      "args": ["your_install_path/fal-mcp-server/build/index.js"],
      "env": {
        "FAL_KEY": "your_fal_key_here"
      }
    }
  }
}

Available Tools

generate-video

It uses AI models to generate videos from text prompts and/or images.

Parameters:

prompt (required): A text description of the content of the video you want to generate.
image_url (optional): The starting image URL for the video (URL or base64 data URI).
end_image_url (optional): The end image URL for the video (URL or base64 data URI).
aspect_ratio (default "16:9"): Video aspect ratio ("16:9", "9:16", "4:3", "3:4", "21:9", "9:21")
resolution (default "540p"): Video resolution ("540p", "720p", "1080p")
duration (default "5s"): video length ("5s", "9s")
loop (default false): whether the video should loop
model (default "luma"): AI model to use ("luma"=Ray2, "kling"=Kling v1.6 Pro)

check-video-status

Check the status of your video generation request.

Parameters:

request_id (required): The request ID to check.
model (default "luma"): AI model used for the request ("luma"=Ray2, "kling"=Kling v1.6 Pro)

Claude usage example

猫が毛糸玉で遊んでいる動画を生成してください。縦向きモードでお願いします。Klingモデルを使用してください。

Claude calls the generate-video tool with the appropriate parameters and provides the resulting video URL.

Compare Models

Luma Ray2 Flash : Excellent for smooth motion and realistic physics, producing natural results.
Kling v1.6 Pro : Excellent for detailed textures and special effects, producing stylized results.

Depending on the prompt and the desired outcome, different models may work best.

Limitations

Video generation may take some time (especially at higher resolutions)
A valid FAL.AI API key and sufficient credits are required
Higher resolution and longer videos cost more credits
Both models consume FAL.AI credits (prices may vary per model)

troubleshooting

API Key Error

Make sure the FAL_KEY environment variable is set correctly, or you can set it directly in the Claude Desktop configuration file.

Video Generation Error

If an error occurs during video generation, a detailed error message will be logged. Common issues are:

Invalid or expired API key
Insufficient credits on your account
Inappropriate prompts or images
A temporary server-side issue

If the error persists, wait a while and try again or try changing the prompt.
