Configuration

Environment Variables

Set your fal.ai API key as an environment variable:

export FAL_KEY="your_fal_api_key_here"

You can get your API key from fal.ai.

MCP Client Configuration

Add this server to your MCP client configuration. For example, in Claude Desktop's config file:

{
  "mcpServers": {
    "fal-minimax-image-01": {
      "command": "npx",
      "args": ["-y", "https://github.com/PierrunoYT/fal-minimax-image-01-mcp-server.git"],
      "env": {
        "FAL_KEY": "your_fal_api_key_here"
      }
    }
  }
}

If the package is published to npm, you can use:

{
  "mcpServers": {
    "fal-minimax-image-01": {
      "command": "npx",
      "args": ["fal-minimax-image-01-mcp-server"],
      "env": {
        "FAL_KEY": "your_fal_api_key_here"
      }
    }
  }
}

Alternatively, if you've cloned the repository locally:

{
  "mcpServers": {
    "fal-minimax-image-01": {
      "command": "node",
      "args": ["/path/to/fal-minimax-image-01-mcp-server/build/index.js"],
      "env": {
        "FAL_KEY": "your_fal_api_key_here"
      }
    }
  }
}

Available Tools

1. minimax_generate

Generate images using the standard synchronous method.

Parameters:

• prompt (required): Text prompt for image generation (max 1500 characters). Longer text prompts will result in better quality images.

• aspect_ratio (optional): Aspect ratio of the generated image (default: "1:1")

• num_images (optional): Number of images to generate (1-9, default: 1)

• prompt_optimizer (optional): Whether to enable automatic prompt optimization (default: false)

Example:

{
  "prompt": "Man dressed in white t shirt, full-body stand front view image, outdoor, Venice beach sign, full-body image, Los Angeles, Fashion photography of 90s, documentary, Film grain, photorealistic",
  "aspect_ratio": "16:9",
  "num_images": 2,
  "prompt_optimizer": true
}

2. minimax_generate_queue

Submit a long-running image generation request to the queue.

Parameters: Same as minimax_generate plus:

• webhook_url (optional): URL for webhook notifications

Returns: A request ID for tracking the job

3. minimax_queue_status

Check the status of a queued request.

Parameters:

• request_id (required): The request ID from queue submission

• logs (optional): Include logs in response (default: true)

4. minimax_queue_result

Get the result of a completed queued request.

Parameters:

• request_id (required): The request ID from queue submission

API Information

• Endpoint: https://fal.run/fal-ai/minimax/image-01

• Model ID: fal-ai/minimax/image-01

• Category: text-to-image

• Kind: inference

• Tags: stylized, realism

Aspect Ratios

The MiniMax model supports the following aspect ratios:

• 1:1: Square format (default)

• 16:9: Widescreen landscape

• 4:3: Standard landscape

• 3:2: Classic photo landscape

Prompt Optimization

Enable prompt optimization to enhance your text prompts for better results:

{
  "prompt_optimizer": true
}

When enabled, the AI will automatically improve your prompt to generate higher quality images. This is disabled by default.

Output

Generated images are automatically downloaded to a local images/ directory with descriptive filenames. The response includes:

• Local file paths

• Original URLs

• Image dimensions (when available)

• Content types

• File sizes

• Generation parameters used

• Request IDs for tracking

Error Handling

The server provides detailed error messages for:

• Missing API keys

• Invalid parameters

• Network issues

• API rate limits

• Generation failures

• Prompt length violations (max 1500 characters)

Tips for Better Results

1. Use Detailed Prompts: Longer, more descriptive prompts generally produce better quality images

2. Enable Prompt Optimization: Use prompt_optimizer: true for enhanced results

3. Choose Appropriate Aspect Ratios: Match the aspect ratio to your intended use case

4. Be Specific: Include details about style, lighting, composition, and quality level

5. Use Style Keywords: Terms like "photorealistic", "cinematic", "detailed", "high resolution" can improve output
