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.

• 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
