Build a Shopify store chat agent with Shopify MCP and C1 by Thesys

Description

Build your own Shopify Store Agent with Shopify MCP and C1 by Thesys
This n8n template can setup a embeddable web chat widget for your Shopify store.
Check out a working demo of this template here.
What this workflow does
A user sends a message in the n8n Chat UI (public chat trigger).
The AI Agent interprets the request.
The agent calls CoinGecko Free MCP to fetch market data (prices, coins, trending, etc.).
The model responds through C1 by Thesys with a streaming, UI answer.
Example prompts you can try right away
Copy/paste any of these into the chat:
“What are the products in the catalog?”
"Purchase white shirt"
"Checkout my cart"
How it works
User sends a prompt
C1 model based on prompt will use Shopify MCP to fetch live catalog
C1 Model generates a UI Schema Response
Schema is rendered as UI using Thesys GenUI SDK on the frontend
Setup
Make sure you have the following:
1. Thesys API Key
You’ll need an API key to authenticate and use Thesys services.
Get your key here
2. Shopify MCP URL
You’ll need the URL of your Shopify Storefront MCP to access the catalog.
For more information, please refer to the Shopify MCP Docs.
What is C1 by Thesys?
C1 by Thesys is an API middleware that augments LLMs to respond with interactive UI (charts, buttons, forms) in real time instead of text.
