fal-ai-media

name	fal-ai-media
description	Unified media generation via fal.ai MCP — image, video, and audio. Covers text-to-image (Nano Banana), text/image-to-video (Seedance, Kling, Veo 3), text-to-speech (CSM-1B), and video-to-audio (ThinkSound). Use when the user wants to generate images, videos, or audio with AI.

fal.ai Media Generation

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 ~/.codex.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 keyword
• find — Get model details and parameters
• generate — Run a model with parameters
• result — Check async generation status
• status — Check job status
• cancel — Cancel a running job
• estimate_cost — Estimate generation cost
• models — List popular models
• upload — Upload files for use as inputs

Image Generation

Nano Banana 2 (Fast)

generate(
  model_name: "fal-ai/nano-banana-2",
  input: {
    "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(
  model_name: "fal-ai/nano-banana-pro",
  input: {
    "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(
  model_name: "fal-ai/nano-banana-2",
  input: {
    "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(
  model_name: "fal-ai/seedance-1-0-pro",
  input: {
    "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(
  model_name: "fal-ai/kling-video/v3/pro",
  input: {
    "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(
  model_name: "fal-ai/veo-3",
  input: {
    "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(
  model_name: "fal-ai/seedance-1-0-pro",
  input: {
    "prompt": "camera slowly zooms out, gentle wind moves the trees",
    "image_url": "<uploaded_image_url>",
    "duration": "5s"
  }
)

Video Parameters

Param	Type	Options	Notes

ElevenLabs (via API, no MCP)

For professional voice synthesis, use ElevenLabs directly:

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(model_name: "fal-ai/nano-banana-pro", input: {...})

Model Discovery

Find models for specific tasks:

search(query: "text to video")
find(model_name: "fal-ai/seedance-1-0-pro")
models()

Tips

• Use seed for 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_cost before running expensive video generations
