fal.ai Media Generation
Drift-prone skill. fal.ai model IDs, pricing, inputs, and MCP tool names change quickly. Search or fetch the current model metadata before promising a specific model, parameter, output format, or cost.
Generate images, videos, and audio using fal.ai models via MCP.
When to Activate
- User wants to generate images from text prompts
- Creating videos from text or images
- Generating speech, music, or sound effects
- Any media generation task
- User says "generate image", "create video", "text to speech", "make a thumbnail", or similar
MCP Requirement
fal.ai MCP server must be configured. Add to ~/.claude.json:
"fal-ai": {
"command": "npx",
"args": ["-y", "fal-ai-mcp-server"],
"env": { "FAL_KEY": "YOUR_FAL_KEY_HERE" }
}
Get an API key at fal.ai.
MCP Tools
The fal.ai MCP provides these tools:
search— Find available models by keywordfind— Get model details and parametersgenerate— Run a model with parametersresult— Check async generation statusstatus— Check job statuscancel— Cancel a running jobestimate_cost— Estimate generation costmodels— List popular modelsupload— Upload files for use as inputs
Image Generation
Nano Banana 2 (Fast)
Best for: quick iterations, drafts, text-to-image, image editing.
generate(
app_id: "fal-ai/nano-banana-2",
input_data: {
"prompt": "a futuristic cityscape at sunset, cyberpunk style",
"image_size": "landscape_16_9",
"num_images": 1,
"seed": 42
}
)
Nano Banana Pro (High Fidelity)
Best for: production images, realism, typography, detailed prompts.
generate(
app_id: "fal-ai/nano-banana-pro",
input_data: {
"prompt": "professional product photo of wireless headphones on marble surface, studio lighting",
"image_size": "square",
"num_images": 1,
"guidance_scale": 7.5
}
)
Common Image Parameters
| Param | Type | Options | Notes |
|---|---|---|---|
prompt |
string | required | Describe what you want |
image_size |
string | square, portrait_4_3, landscape_16_9, portrait_16_9, landscape_4_3 |
Aspect ratio |
num_images |
number | 1-4 | How many to generate |
seed |
number | any integer | Reproducibility |
guidance_scale |
number | 1-20 | How closely to follow the prompt (higher = more literal) |
Image Editing
Use Nano Banana 2 with an input image for inpainting, outpainting, or style transfer:
# First upload the source image
upload(file_path: "/path/to/image.png")
# Then generate with image input
generate(
app_id: "fal-ai/nano-banana-2",
input_data: {
"prompt": "same scene but in watercolor style",
"image_url": "<uploaded_url>",
"image_size": "landscape_16_9"
}
)
Video Generation
Seedance 1.0 Pro (ByteDance)
Best for: text-to-video, image-to-video with high motion quality.
generate(
app_id: "fal-ai/seedance-1-0-pro",
input_data: {
"prompt": "a drone flyover of a mountain lake at golden hour, cinematic",
"duration": "5s",
"aspect_ratio": "16:9",
"seed": 42

### Kling Video v3 Pro
Best for: text/image-to-video with native audio generation.
generate( app_id: "fal-ai/kling-video/v3/pro", input_data: { "prompt": "ocean waves crashing on a rocky coast, dramatic clouds", "duration": "5s", "aspect_ratio": "16:9" } )
### Veo 3 (Google DeepMind)
Best for: video with generated sound, high visual quality.
generate( app_id: "fal-ai/veo-3", input_data: { "prompt": "a bustling Tokyo street market at night, neon signs, crowd noise", "aspect_ratio": "16:9" } )
### Image-to-Video
Start from an existing image:
generate( app_id: "fal-ai/seedance-1-0-pro", input_data: { "prompt": "camera slowly zooms out, gentle wind moves the trees", "image_url": "<uploaded_image_url>", "duration": "5s" } )
### Video Parameters
| Param | Type | Options | Notes |
|-------|------|---------|-------|
| `prompt` | string | required | Describe the video |
| `duration` | string | `"5s"`, `"10s"` | Video length |
| `aspect_ratio` | string | `"16:9"`, `"9:16"`, `"1:1"` | Frame ratio |
| `seed` | number | any integer | Reproducibility |
| `image_url` | string | URL | Source image for image-to-video |

## Audio Generation
### CSM-1B (Conversational Speech)
Text-to-speech with natural, conversational quality.
generate( app_id: "fal-ai/csm-1b", input_data: { "text": "Hello, welcome to the demo. Let me show you how this works.", "speaker_id": 0 } )
### ThinkSound (Video-to-Audio)
Generate matching audio from video content.
generate( app_id: "fal-ai/thinksound", input_data: { "video_url": "<video_url>", "prompt": "ambient forest sounds with birds chirping" } )
### ElevenLabs (via API, no MCP)
For professional voice synthesis, use ElevenLabs directly:
```python
import os
import requests
resp = requests.post(
"https://api.elevenlabs.io/v1/text-to-speech/<voice_id>",
headers={
"xi-api-key": os.environ["ELEVENLABS_API_KEY"],
"Content-Type": "application/json"
},
json={
"text": "Your text here",
"model_id": "eleven_turbo_v2_5",
"voice_settings": {"stability": 0.5, "similarity_boost": 0.75}
}
)
with open("output.mp3", "wb") as f:
f.write(resp.content)
VideoDB Generative Audio
If VideoDB is configured, use its generative audio:
# Voice generation
audio = coll.generate_voice(text="Your narration here", voice="alloy")
# Music generation
music = coll.generate_music(prompt="upbeat electronic background music", duration=30)
# Sound effects
sfx = coll.generate_sound_effect(prompt="thunder crack followed by rain")
Cost Estimation
Before generating, check estimated cost:
estimate_cost(
estimate_type: "unit_price",
endpoints: {
"fal-ai/nano-banana-pro": {
"unit_quantity": 1
}
}
)
Model Discovery
Find models for specific tasks:
search(query: "text to video")
find(endpoint_ids: ["fal-ai/seedance-1-0-pro"])
models()
Tips
- Use
seedfor reproducible results when iterating on prompts - Start with lower-cost models (Nano Banana 2) for prompt iteration, then switch to Pro for finals
- For video, keep prompts descriptive but concise — focus on motion and scene
- Image-to-video produces more controlled results than pure text-to-video
- Check
estimate_costbefore running expensive video generations
