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

1. Clone this repository

2. Install the dependencies:

   npm install

3. 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

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

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.
