Installation

Quick Install with Claude Desktop

The easiest way to add this server to Claude Desktop:

claude mcp add gelato --env GELATO_API_KEY="your_gelato_api_key_here" -- uvx mcp-server-gelato

Replace your_gelato_api_key_here with your actual Gelato API key from the Gelato API Portal.

Alternative: You can install without the API key and configure it later:

claude mcp add gelato -- uvx mcp-server-gelato

Then use the configure_gelato tool within Claude to set up your API key.

Manual Installation

Option 1: Install from PyPI (Recommended)

# Install the package
uv install mcp-server-gelato
or
pip install mcp-server-gelato
Run the server
GELATO_API_KEY="your_api_key_here" uvx mcp-server-gelato
Or install as a tool
uv tool install mcp-server-gelato
GELATO_API_KEY="your_api_key_here" mcp-server-gelato

Option 2: Install from GitHub

# Install directly from GitHub
uvx --from git+https://github.com/madzarmaksim/mcp-server-gelato mcp-server-gelato
Or use uv tool install
uv tool install git+https://github.com/madzarmaksim/mcp-server-gelato

Option 3: Local Development

1. Clone this repository:

   git clone https://github.com/madzarmaksim/mcp-server-gelato.git
   cd mcp-server-gelato
   

2. Install dependencies:

   uv install

   # or

   pip install -e .

   

3. Set up your API key:

   cp .env.example .env

   # Edit .env and add your GELATO_API_KEY

   

Configuration

Create a .env file in the project root with your Gelato API key:

GELATO_API_KEY=your_gelato_api_key_here
Optional configuration
GELATO_BASE_URL=https://order.gelatoapis.com
GELATO_PRODUCT_URL=https://product.gelatoapis.com
TIMEOUT=30
MAX_RETRIES=3
DEBUG=false

Usage

Running the Server

After installation via uvx:

# Run the server directly
mcp-server-gelato
Or with environment variables
GELATO_API_KEY=your_key_here mcp-server-gelato

Local development:

# Direct execution
python main.py
Development mode with inspector
uv run mcp dev main.py
Install in Claude Desktop from local directory
uv run mcp install . --name "Gelato API"

Using the Tools and Resources

Search Orders

# Search for draft orders
search_orders(order_types=["draft"])
Search US orders from last month
search_orders(
    countries=["US"], 
    start_date="2024-01-01T00:00:00Z",
    end_date="2024-01-31T23:59:59Z"
)
Search by customer name
search_orders(search_text="John Smith", limit=10)

Get Order Details

Use the resource URI format to load order context:

orders://37365096-6628-4538-a9c2-fbf9892deb85

Or use the tool:

get_order_summary(order_id="37365096-6628-4538-a9c2-fbf9892deb85")

Explore Product Catalogs

catalogs://list          # List all catalogs
catalogs://posters       # Get poster catalog details
catalogs://summary       # Quick overview

Available Search Filters

The search_orders tool supports extensive filtering:

- order_types: ["order", "draft"] - Filter by order type
- countries: ["US", "DE", "CA"] - Filter by shipping country
- currencies: ["USD", "EUR", "GBP"] - Filter by currency
- financial_statuses: Payment statuses ("draft", "paid", "canceled", etc.)
- fulfillment_statuses: Fulfillment statuses ("created", "printed", "shipped", etc.)
- search_text: Search in customer names and order reference IDs
- start_date/end_date: Date range filtering (ISO 8601 format)
- channels: ["api", "shopify", "etsy", "ui"] - Filter by order channel
- limit/offset: Pagination control (max 100 results per request)

Key Design Features

- Type Safety: Full Pydantic models for all API interactions
- Error Handling: Comprehensive error handling with custom exceptions
- Async Support: All API calls are async for better performance
- Resource vs Tools: Clear separation between data exposure (resources) and operations (tools)
- Extensible: Easy to add new endpoints by following established patterns

Error Handling

The server includes robust error handling for common scenarios:

- Authentication errors: Invalid or missing API keys
- Rate limiting: Automatic retry with exponential backoff
- Network errors: Timeout and connection error handling
- API errors: Proper handling of Gelato API error responses
- Validation errors: Request/response data validation

Troubleshooting

"Failed to reconnect to gelato" Error

This error occurs when the server starts without a valid GELATO_API_KEY. Here are the solutions:

For Claude Desktop Installation:

# Install with API key (recommended)

claude mcp add gelato --env GELATO_API_KEY="your_actual_api_key" -- uvx mcp-server-gelato

Or install without API key and configure later
claude mcp add gelato -- uvx mcp-server-gelato
Then use the configure_gelato tool in Claude

For Local Development:

# Using PyPI package

GELATO_API_KEY="your_api_key_here" uvx mcp-server-gelato

Or using local code
export GELATO_API_KEY=your_api_key_here
python main.py
Or create .env file for local development
echo "GELATO_API_KEY=your_api_key_here" > .env
python main.py

Getting Your API Key

1. Visit the Gelato API Portal
2. Sign up or log in to your account
3. Generate an API key from your dashboard
4. Use the key in the installation command or environment variable

Common Issues

- Invalid API Key: Double-check your API key is correct and active
- Network Issues: Ensure internet connectivity and no firewall blocking
- Permission Issues: Make sure your API key has the necessary permissions

Development

Adding New Features

1. New Tools: Add to src/tools/ and register in server
2. New Resources: Add to src/resources/ and register in server
3. New Models: Add to src/models/ with proper Pydantic validation
4. New API Endpoints: Extend GelatoClient in src/client/

Testing

# Test connection with your API key
python -c "
import asyncio
from src.config import get_settings
from src.client.gelato_client import GelatoClient
async def test():

    settings = get_settings()

    async with GelatoClient(settings.gelato_api_key, settings) as client:

        catalogs = await client.list_catalogs()

        print(f'Found {len(catalogs)} catalogs')
asyncio.run(test())

"

Troubleshooting

Common Issues

1. API Key Error: Make sure GELATO_API_KEY is set correctly in your environment
2. Connection Timeout: Check your network connection and increase timeout in config
3. Rate Limiting: The server automatically retries with backoff, but you may need to slow down requests

Debug Mode

Enable debug logging:

DEBUG=true python main.py

Contributing

1. Follow the existing code structure and patterns
2. Add proper error handling for new endpoints
3. Include Pydantic models for data validation
4. Document new features in this README
