VerifiedSTDIODesktop onlyBrowser AutomationBusiness & Commerce

Overview

AI-generated overview

Connects an AI assistant to H-E-B grocery stores so it can search stores and products, manage a cart, and clip digital coupons.

What you can do
  • Find H-E-B stores by address or zip code and set a preferred store
  • Search products with pricing and availability, in batches too, and read ingredients, nutrition, allergens and dietary attributes
  • View, add, bulk-add and remove cart items, with confirmation required for changes
  • List, search, clip and review digital coupons
  • Check, refresh, save credentials for and clear the H-E-B session
When to use it
Useful when you shop at H-E-B and want an assistant to look up products and prices, check ingredients or allergens, build a cart, or collect coupons through conversation instead of the website.
Requirements
Runs locally as a Python package (pip install texas-grocery-mcp); the optional browser extra plus Playwright Chromium enables fast session refresh. Cart operations and session management also need the Playwright MCP server installed via npm. Optional environment variables HEB_DEFAULT_STORE, REDIS_URL and LOG_LEVEL. An H-E-B account is needed for cart and coupon actions.
Before you install
Uses unofficial web APIs and browser automation against HEB.com and is not affiliated with H-E-B, so usage may conflict with the site's terms. Cart and coupon tools change real account data, and coupon_clip and cart_add take a confirm flag. session_save_credentials stores your H-E-B email and password in the system keyring for automatic login. H-E-B bot detection expires sessions roughly every 11 minutes.

Installation

In SourceWeft

  1. Open Texas Grocery in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
