How to Set Up and Use Kroger MCP
Kroger MCP Server is a Python FastMCP server that gives AI assistants like Claude access to Kroger's full grocery shopping platform via the official Kroger API. It enables finding stores by zip code, searching products with pricing data, managing shopping carts, and completing purchases — all through natural-language requests. The server uses OAuth2 for user authentication, so cart and purchase operations act on behalf of a real Kroger account, making it a practical tool for AI-assisted grocery planning and shopping automation.
Prerequisites
- Python 3.10 or higher with uv or pip
- Free Kroger Developer API credentials (Client ID, Client Secret, Redirect URI) from https://developer.kroger.com
- A Kroger customer account (required for cart and purchase operations)
- An MCP-compatible client such as Claude Desktop
Register for Kroger API credentials
Visit https://developer.kroger.com/manage/apps/register, create a developer account, register a new application, and record your Client ID, Client Secret, and the Redirect URI you configure (typically http://localhost:8000/callback).
Install the package
Install kroger-mcp from PyPI using uv (recommended) or pip. macOS users must clone the repo and use Option 2 with a local uv run command.
# Linux / Windows — install from PyPI:
uv pip install kroger-mcp
# macOS — clone and run locally:
git clone https://github.com/CupOfOwls/kroger-mcp
cd kroger-mcp
uv syncConfigure environment variables
Create a .env file in the project root or pass credentials via the MCP client config. KROGER_USER_ZIP_CODE sets the default location for store searches.
KROGER_CLIENT_ID=your_client_id_here
KROGER_CLIENT_SECRET=your_client_secret_here
KROGER_REDIRECT_URI=http://localhost:8000/callback
KROGER_USER_ZIP_CODE=90274Add to Claude Desktop configuration
Add the kroger-mcp server entry to claude_desktop_config.json. Use uvx for PyPI-installed packages (Linux/Windows) or the local uv run form for macOS clones.

}
}
}
}Authorize your Kroger account on first use
The first time you invoke a cart or purchase tool, the server will open a browser window asking you to log in to Kroger and authorize your registered developer app. This grants the server access to act on your behalf.

Natural-language shopping prompts that exercise the store search, product search, and cart management tools.
- "Find the closest Kroger store to zip code 90274."
- "Search for organic whole milk and show me the prices at my preferred store."
- "Add two gallons of 2% milk and a dozen eggs to my cart."
- "Show me what's currently in my cart."
- "Find a recipe for chicken stir fry and add all the ingredients to my cart."Troubleshooting Kroger MCP
macOS users get an error when using the uvx installation method
The README explicitly states that macOS users must use Option 2: clone the repository locally and configure with 'uv run' pointing to the cloned directory. The uvx method is not supported on macOS.
OAuth authorization page never opens, or the callback returns a redirect error
Ensure KROGER_REDIRECT_URI in your .env or MCP config exactly matches the redirect URI registered in your Kroger Developer Portal app settings, including the http/https scheme and port number.
Product searches return empty results
Confirm KROGER_USER_ZIP_CODE is set to a valid US zip code served by Kroger. Use the search_locations tool first to verify stores exist in your area before searching products.
