Kroger

What the kroger MCP server does

The kroger MCP server gives an MCP client access to common Kroger grocery workflows. Agents can authenticate a Kroger account, select a preferred store by ZIP code or store ID, search products by name, brand, or category, and retrieve product details such as nutrition information.

Shopping workflows cover adding products to a cart, reviewing cart contents and totals, changing quantities, and removing items. The server also exposes digital coupon actions, including listing available coupons and clipping selected coupons to a Kroger Plus card. Fuel-points tools return the account balance and available rewards.

For fulfillment, agents can request delivery or pickup time slots and proceed to checkout. Order-history and reorder tools support reviewing recent purchases and placing repeat orders. The connector also supports Kroger-owned banners listed in the README, including Ralphs, Fred Meyer, King Soopers, Fry's, Smith's, QFC, and Harris Teeter.

How it works

Each capability is available as a named MCP tool. A typical flow starts with kroger_login, followed by kroger_set_store and kroger_search_products. The agent can inspect product details, add selected product IDs to the cart, apply coupons, and review totals before requesting fulfillment slots and calling checkout.

Pickup and delivery are separate slot queries, so the agent can choose the fulfillment method before checkout. The server also supports an alternate workflow in which an agent reads order history and uses kroger_reorder for a previous purchase.

Setup and configuration

Install the package with npm:

npm install @striderlabs/mcp-kroger

Register it in the MCP client configuration as a command-based server:

{
  "mcpServers": {
    "kroger": {
      "command": "npx",
      "args": ["@striderlabs/mcp-kroger"]
    }
  }
}

The documented runtime requirement is Node.js 18 or newer. The account requirement is a Kroger account with a Kroger Plus card. No environment variables are specified in the provided configuration.
