One connection in front, every store behind it
AI assistants can only use the tools you connect. Connecting every store one by one does not scale, so Nexva One does it once for you.
Your assistant
Claude, ChatGPT, Cursor or any MCP client. It knows one address: the Nexva One connector.
Nexva One
Searches every listed store at once, keeps one cart across stores and shows results as cards you can browse.
The stores
Each store answers with its own live products, prices and stock, and runs its own checkout.
Who does what
| Question | Answer |
|---|---|
| Who is the seller? | The store. It sells, ships and is the seller of record. |
| Where do I pay? | On the store’s own checkout. A cart with several stores is paid one store at a time. |
| Who handles refunds and returns? | The store that sold the item. Nexva One can show you its order page. |
| Where do I sign in? | On the card inside your assistant. Never type a password or card number into the chat. |
| Is a listing an endorsement? | No. Some stores are partners; others are public storefronts we list independently. |
Open standards
Nexva One is built on the Model Context Protocol (MCP), the open standard AI assistants use to connect to tools. It reads stores that publish open commerce endpoints such as Shopify’s storefront catalog and the Universal Commerce Protocol, and it will add WebMCP sites as browsers ship that standard.
