Integrate AI with Rohlik Grocery Services

Rohlik MCP Server

Enhance your favourite LLM with capabilities to buy groceries.

This is a Model Context Protocol (MCP) server that enables AI assistants to interact with the Rohlik Group's online grocery delivery services across multiple countries. This server provides tools for searching products, managing shopping carts, and accessing account info.

Supported Services:

• 🇨🇿 Rohlik.cz - Czech Republic
• 🇩🇪 Knuspr.de - Germany
• 🇦🇹 Gurkerl.at - Austria
• 🇭🇺 Kifli.hu - Hungary
• 🇷🇴 Sezamo.ro - Romania
• 🇮🇹 Sezamo.it - Italy (planned)
• 🇪🇸 Sezamo.es - Spain (planned)

Example LLM prompts that work very well with the Rohlik MCP:

🛒 Regular Shopping:

• Add ingredients for apple pie to the cart. Only gluten-free and budget-friendly.
• Or actually, instead of apple pie I want to make pumpkin pie. Change the ingredients.
• What are the items in my cart?
• Add the items in the attached shopping list photo to the cart.
• Add the bread I marked as favorite in Rohlik to my cart.

🤖 Smart Shopping:

• "Add breakfast items I typically order"
• "Show me lunch suggestions for this week"
• "What do I usually buy for dinner?"
• "I need snacks - suggest what I normally order"
• "Show my top 20 most purchased items"
• "What can I do with Rohlik MCP?"

💰 Deals & Discounts:

Testing

Unit Tests

The project includes unit tests for smart shopping data transformation logic:

# Run all tests

npm run test:coverage

What's tested:

• Frequency analysis algorithms (get_frequent_items)
• Meal suggestion filtering and ranking (get_meal_suggestions)
• Price averaging and calculations
• Category filtering and grouping
• Edge cases (empty data, missing fields, etc.)

See tests/README.md for detailed testing documentation.

Testing with Claude Desktop

Add this to configuration:

{
  "mcpServers": {
    "rohlik-local": {
      "command": "node",
      "args": ["/path/to/rohlik-mcp/dist/index.js"],
      "env": {
        "ROHLIK_USERNAME": "your-email@example.com",
        "ROHLIK_PASSWORD": "your-password",
        "ROHLIK_BASE_URL": "https://www.rohlik.cz"
      }
    }
  }
}

Debug Mode

If you're experiencing authentication issues, enable debug mode to see detailed logs:

{
  "mcpServers": {
    "rohlik-local": {
      "command": "node",
      "args": ["/path/to/rohlik-mcp/dist/index.js"],
      "env": {
        "ROHLIK_USERNAME": "your-email@example.com",
        "ROHLIK_PASSWORD": "your-password",
        "ROHLIK_BASE_URL": "https://www.rohlik.cz",
        "ROHLIK_DEBUG": "true"
      }
    }
  }
}

Debug logs will appear in ~/Library/Logs/Claude/mcp-server-rohlik-local.log (macOS) or %APPDATA%/Claude/logs/mcp-server-rohlik-local.log (Windows).

Testing with MCP Inspector

You can test the MCP server using the official MCP Inspector (https://modelcontextprotocol.io/legacy/tools/inspector):

npm run inspect

In the Inspector, set the ROHLIK_USERNAME and ROHLIK_PASSWORD envs.

API Validation Tool

To validate that all Rohlik API endpoints are working correctly and diagnose authentication issues:

npm run validate-api

This will:

• Test all 11 API endpoints used by the MCP server
• Show detailed HTTP request/response logs in the console
• Generate a JSON report: tests/validation-results.json
• Generate a beautiful HTML report: tests/validation-report.html

The validator automatically loads credentials from your Claude Desktop config or environment variables. Open the HTML report in your browser for an easy-to-read summary of all tests.

Troubleshooting

Common Issues

Claude Desktop does not see the MCP server (on Windows)

For your config file, instead of %APPDATA%/Claude/claude_desktop_config.json use C:\Users\[YOUR WINDOWS USER]\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json

"Login failed" Error

Possible causes:

1. Wrong username/password in configuration
2. Rohlik API changed or is temporarily unavailable
3. Network connectivity issues

Solutions:

1. Verify credentials in your claude_desktop_config.json
2. Enable debug mode: "ROHLIK_DEBUG": "true" in env section
3. Check logs: ~/Library/Logs/Claude/mcp-server-rohlik*.log (macOS) or %APPDATA%\Claude\logs\mcp-server-rohlik*.log (Windows)
4. Run API validator: npm run validate-api to test all endpoints

"No order history found"

Cause: Your account has no past orders, or orders are not accessible

Solution: Ensure you have at least one completed order on Rohlik before using smart shopping features (get_meal_suggestions, get_frequent_items)

Slow response times

Causes:

• Analyzing too many orders (smart shopping features)
• Network latency to Rohlik servers
• API rate limiting

Solutions:

• For smart shopping: reduce number of orders analyzed (try 10 instead of default 20)
• Use fewer requests or add delays between bulk operations
• Check your network connection

Products not found or search returns no results

Causes:

• Product out of stock or discontinued
• Product ID changed in Rohlik system
• Spelling mistake in search query

Solutions:

• Search by partial name instead of full product name
• Try alternative spellings or broader search terms
• Verify product exists on Rohlik website directly

Server fails with spawn npx ENOENT

Under Claude Desktop, fails with:

spawn npx ENOENT
Server disconnected. Transport closed unexpectedly.

Solutions:

• Change config to use absolute path to npx as /Users/adam/.local/share/mise/installs/node/22.14.0/bin/npx)
• See more info: https://github.com/tomaspavlin/rohlik-mcp/issues/6

Enabling Debug Mode

Add ROHLIK_DEBUG to your configuration to see detailed logs:

{
  "mcpServers": {
    "rohlik-local": {
      "command": "node",
      "args": ["/path/to/rohlik-mcp/dist/index.js"],
      "env": {
        "ROHLIK_USERNAME": "your-email@example.com",
        "ROHLIK_PASSWORD": "your-password",
        "ROHLIK_BASE_URL": "https://www.rohlik.cz",
        "ROHLIK_DEBUG": "true"
      }
    }
  }
}

View logs:

# macOS
tail -f ~/Library/Logs/Claude/mcp-server-rohlik-local.log

# Windows
type %APPDATA%\Claude\logs\mcp-server-rohlik-local.log

Using the API Validation Tool

If you encounter authentication or API issues, run the validator:

npm run validate-api

This will:

• Test all 11 API endpoints used by the MCP
• Show detailed HTTP request/response information
• Generate validation-results.json with test results
• Create validation-report.html for easy viewing in browser
• Help identify which specific endpoints are failing
