The first time you run a tool requiring user authentication, you'll be prompted to authorize your app through your web browser. You're granting permission to your own registered app, not to any third party.
Installation
Option 1: Using uvx with Claude Desktop (Recommended)
Once published to PyPI, you can use uvx to run the package directly without cloning the repository:
Edit Claude Desktop's configuration file:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json
Benefits of this method:
- Automatically installs the package from PyPI if needed
- Creates an isolated environment for running the server
- Makes it easy to stay updated with the latest version
- Doesn't require maintaining a local repository clone
Option 2: Using uv with a Local Clone
First, clone locally:
Then, edit Claude Desktop's configuration file:
Option 3: Installing From PyPI
Option 4: Installing From Source

🧰 Local-Only Cart Tracking
Since the Kroger API doesn't provide cart viewing functionality, this server maintains local tracking:
Local Cart Storage
- File:
kroger_cart.json - Contents: Current cart items with timestamps
- Automatic: Created and updated automatically
Order History
- File:
kroger_order_history.json - Contents: Historical orders with placement timestamps
- Usage: Move completed carts to history with
mark_order_placed
🚧 Kroger Public API Limitations
- View Only: The
remove_from_cartandclear_current_carttools ONLY affect local tracking, not the actual Kroger cart - Local Sync: Use these tools only when the user has already removed items from their cart in the Kroger app/website
- One-Way: Items can be added to the Kroger cart but not removed through the Public API. The Partner API would allow these things, but that requires entering a contract with Kroger.
| API | Version | Rate Limit | Notes |

| Authorization | 1.0.13 | No specific limit | Token management |
