High-performance MCP server for FAL AI image and video generation with automatic downloads
Seamless bridge between FAL AI's powerful image and video generation capabilities and MCP-compatible clients like Claude. All generated content is automatically downloaded to your local machine while providing public URLs, data URLs, and local file paths.
- Get your FAL API key from fal.ai
- Add to Claude Desktop configuration:
{
"mcpServers": {
"fal-image-video": {
"command": "npx",
"args": ["-y", "fal-image-video-mcp"],
"env": {
"FAL_KEY": "YOUR-FAL-AI-API-KEY"
}
}
}
}- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%/Claude/claude_desktop_config.json - Linux:
~/.config/Claude/claude_desktop_config.json
{
"mcpServers": {

"args": ["-y", "fal-image-video-mcp"],
"env": {
"FAL_KEY": "YOUR-FAL-AI-API-KEY",
"DOWNLOAD_PATH": "/custom/download/path",
"ENABLE_DATA_URLS": "true",
"MAX_DATA_URL_SIZE": "1048576",
"AUTOOPEN": "false"
}
}
}
}Environment Variables:
FAL_KEY(required): Your FAL AI API keyDOWNLOAD_PATH(optional): Custom download directory (defaults to ~/Downloads)ENABLE_DATA_URLS(optional): Enable/disable data URLs (default: false, optimized for Claude Desktop)MAX_DATA_URL_SIZE(optional): Max file size for data URLs in bytes (default: 2MB)AUTOOPEN(optional): Automatically open generated files with default application (default: true, cross-platform)
- Visit fal.ai and create an account
- Navigate to your API keys section
- Generate a new API key
- Replace
YOUR-FAL-AI-API-KEYwith your actual key - Restart Claude Desktop
All generated content is automatically saved to your local machine!
- Images: Downloaded as
.jpgfiles - Videos: Downloaded as
.mp4files - Location:

}
}Why this works better for Claude Desktop:
- β Local file paths allow Claude to directly access downloaded images
- β No large data URLs that overwhelm the context
- β Auto-open files instantly display generated content in default applications
- β Public URLs available for sharing if needed
- β Size limits prevent context overflow

Yes! You can absolutely pass generated images back to Claude and use them for video generation. Here's how:
- Generate an image using any image model:
{
"tool": "imagen4",
"arguments": {
"prompt": "A majestic mountain landscape at sunset"
}
}- Use the returned image URL in any image-to-video model:
{
"tool": "kling_master_image",
"arguments": {
"image_url": "<URL_FROM_PREVIOUS_GENERATION>",
"prompt": "Gentle clouds moving across the sky",
"duration": 5
}
}This MCP server features comprehensive model access:
Use list_available_models to see all models in the registry:
{
"tool": "list_available_models",
"arguments": {
"category": "imageGeneration"
}
}Use execute_custom_model to run ANY FAL endpoint beyond our registry:
{
"tool": "execute_custom_model",
"arguments": {
"endpoint": "fal-ai/custom-model-name",
"input_params": {
"prompt": "Your custom prompt",
"custom_param": "value"
},
"category_hint": "image"
}
}- β 21 curated models from actual FAL AI platform
- β Universal execution for any FAL endpoint
- β Automatic downloading to ~/Downloads (configurable)
- β Triple URL support (public + data + local file URLs)
- β Automatic categorization by type
- β Dynamic tool generation for each model
- β Model-specific parameter handling
- Want to use a model not in our registry? Use
execute_custom_model - Need to see all available models? Use
list_available_models - Want both curated experience AND full flexibility? You got it!
The MCP server provides both public URLs and data URLs for maximum compatibility with Claude and other clients.
Both tools return structured JSON with:
- Public URL: Direct link to the generated content
- Data URL: Base64-encoded data URL for direct embedding
- Metadata: Generation parameters and dimensions
- Claude-compatible format: Ready for immediate use in conversations

}Start HTTP server for testing or integration:
# Start on auto-detected port (default: 3000)
npx -y fal-image-video-mcp --http
# Or specify port via environment
PORT=8080 npx -y fal-image-video-mcp --http
# With custom transport flag
MCP_TRANSPORT=http npx -y fal-image-video-mcpHTTP Endpoints:
GET /health- Server health checkGET /mcp- SSE endpoint for MCP communicationPOST /mcp- JSON-RPC message handling
Test the server:
# Health check
curl http://localhost:3000/health
# List available tools
