Conversational AI Shopping Assistant

WisWes is an AI shopping-assistant platform: a chat widget that drops onto your storefront, talks to shoppers in natural language, and acts on their behalf — searching the catalog, adding to cart, looking up orders, and completing checkout.

The WisWes integration for Magento connects your store to the WisWes assistant over the Model Context Protocol. Shoppers chat in their own words; the assistant calls real Magento APIs through a stateless /mcp endpoint served by your existing web server. Every action — cart updates, order placement, customer profile changes — routes through Magento's standard service contracts, so price rules, sales rules, stock reservations, and your other extensions all fire exactly as they would from the storefront UI.

The integration ships 22 typed tools the assistant can call across catalog, cart, checkout, customer, sales, and wishlist. A one-click admin handshake mints a shared secret and ships it to your WisWes workspace — merchants never see or copy a token. A nightly catalog push populates the WisWes vector index for semantic product search, with an on-demand button for bulk-update days.

Customer-scoped tools (cart, customer profile, orders) forward Magento's standard customer bearer token, so logged-in shoppers see only their own data and anonymous shoppers cannot read carts or orders. Tools throw LocalizedException with shopper-safe messages — internal stack traces never reach the AI. The module passes phpcs --standard=Magento2 with zero errors.

Features

• 22 typed AI tools spanning catalog search, category browse, cart add / update / remove, full checkout (address, shipping, payment, place order), customer profile and addresses, wishlist, and order status
• Stateless /mcp HTTP endpoint served by your existing Magento web server — no extra process or daemon to operate
• One-click admin handshake mints and ships the shared secret automatically; the merchant never handles the token
• Nightly catalog push to the WisWes vector index for semantic product search, with on-demand re-push from the admin or CLI
• Customer-aware: logged-in shoppers' carts, orders, and addresses are private to them
• Drop-in custom tools via the #[McpTool] PHP attribute — no fork required
• Bearer-auth on every request, LocalizedException boundary on every tool — no leaked stack traces
• Compatible with default themes and Hyvä-themed stores out of the box
• Open source under GPL-3.0-or-later — full source on GitHub
• Free forever; no in-extension paywall

Account and Pricing

The integration requires a WisWes account, which you can create at WisWes. The account is not created automatically during install — sign up first, then run the one-click handshake from Magento admin to connect the two.

The Magento integration itself is free and open source. WisWes itself comes with a 14-day free trial — no credit card required. After the trial:

Basic — $39.99/month — 1,000 conversations, plug-and-play widget

Pro — $179.99/month — 10,000 conversations, custom MCP with cart, product, and customer flows

Enterprise — from $499/month — unlimited conversations, A/B testing on prompts and flows, dedicated success manager, 99.9% uptime SLA

Model usage fees (Anthropic, OpenAI, etc.) are pass-through. Typical stores see $15–80/month on Basic, $60–250 on Pro, $200–800 on Enterprise. Bring your own API key to pay providers directly.

Why Model Context Protocol

Model Context Protocol is the open standard for giving AI agents structured access to systems of record — originated by Anthropic, adopted by OpenAI, Google, and most major LLM vendors. WisWes connects to Magento through MCP, so the same integration also works with any future MCP-aware AI tool. Your investment is not locked to a single vendor.
