🛠️ Available MCP Tools

augment_image

Apply image augmentations based on natural language prompt or preset.

# Example usage in MCP client
augment_image(
    image_b64="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQ...",
    prompt="add blur and increase contrast",
    seed=42  # Optional for reproducible results
)

Parameters:

• image_b64 (str): Base64-encoded image data
• prompt (str): Natural language description of desired augmentations
• seed (int, optional): Random seed for reproducible results
• preset (str, optional): Use preset instead of prompt ("segmentation", "portrait", "lowlight")

Returns: Base64-encoded augmented image

list_available_transforms

Get list of supported transforms with descriptions and parameters.

# Returns comprehensive list of available transforms
list_available_transforms()

Returns: List of transform objects with names, descriptions, and parameter ranges

set_default_seed

Set default seed for consistent reproducibility across all augment_image calls.

# Set default seed for all future operations
set_default_seed(seed=42)

# Clear default seed
set_default_seed(seed=None)

Usage Examples

Basic Image Augmentation

# Simple blur and rotation
result = augment_image(
    image_b64=your_image_b64,
    prompt="add blur and rotate 15 degrees"
)

# Multiple transforms
result = augment_image(
    image_b64=your_image_b64,
    prompt="increase brightness, add noise, and flip horizontally"
)

# Reproducible results
result = augment_image(
    image_b64=your_image_b64,
    prompt="add blur and rotate",
    seed=42  # Same seed = same result
)

Using Presets

# Optimized for segmentation tasks
result = augment_image(
    image_b64=your_image_b64,
    preset="segmentation"
)

# Portrait photography enhancements
result = augment_image(
    image_b64=your_image_b64,
    preset="portrait"
)

# Low-light image improvements
result = augment_image(
    image_b64=your_image_b64,
    preset="lowlight"
)

Natural Language Parsing

The parser understands various ways to describe transforms:

• Blur: "add blur", "make blurry", "gaussian blur"
• Rotation: "rotate 15 degrees", "turn clockwise", "rotate left"
• Brightness: "increase brightness", "make brighter", "brighten"
• Contrast: "add contrast", "increase contrast", "make more contrasty"
• Noise: "add noise", "make noisy", "gaussian noise"
• Flipping: "flip horizontally", "mirror", "flip vertical"
• Cropping: "crop center", "random crop", "crop 224x224"

🐛 Troubleshooting

Common Issues

MCP Server Not Starting

# Check if uv is installed
uv --version

# Ensure dependencies are installed
uv sync

# Run with debug logging
MCP_LOG_LEVEL=DEBUG uvx albumentations-mcp

Image Processing Errors

• Ensure image is valid Base64-encoded data
• Check image format is supported (JPEG, PNG, WebP, etc.)
• Verify image size is reasonable (< 10MB recommended)

Natural Language Parsing Issues

• Use simple, clear descriptions: "add blur" vs "make it blurry"
• Check available transforms with list_available_transforms
• Validate prompts with validate_prompt before processing

File Saving Issues

• Hook system creates session directories but file saving may fail
• MCP tools return base64 images correctly (core functionality works)
• CLI demo shows file paths but actual file creation is in development

MCP Client Integration

• Verify MCP client supports stdio transport
• Check configuration file syntax (JSON formatting)
• Ensure uvx command is available in PATH

Getting Help

1. Check the Issues page
2. Run with debug logging: MCP_LOG_LEVEL=DEBUG
3. Test with CLI demo to isolate MCP vs processing issues
4. Review the comprehensive test suite for usage examples
