Shopstr / Nostr marketplace MCP server

Let your AI create and update your Shopstr or Nostr marketplace shop and product listings for you.

This is a small helper that lets your AI set up and update a shop on Shopstr, a marketplace built on Nostr where people sell things for Bitcoin over Lightning. You describe your shop and your products in plain words, and the AI turns that into the right listings. It is handy if you sell things online and would rather not click through a storefront dashboard by hand.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to Shopstr and to Nostr relays, which are the shared servers where marketplace listings live. Once it is connected, you can ask your AI to publish or update your shop and products, and it will do the actual posting for you.

What this MCP server does

You tell your AI what you want, for example a new shop profile or a product with a name and a price. The AI uses this helper to build the right kind of listing behind the scenes. The helper signs the listing with your Nostr identity and sends it out to the relays your audience reads from. For Shopstr, it also nudges Shopstr's own database so your listing actually shows up on the storefront, not just on the relays. Then you get back a short confirmation with the listing's ID and which relays accepted it.

What you can do with it

Create or update your shop profile on Shopstr
Publish a product listing with a title, price, images and categories
Add several photos and category tags to a product so it shows up in search
Create or update a stall and products in the older NIP-15 format for other clients
List your own existing stalls and products so you can see what is published
Turn on a two-step confirm so nothing goes live until you approve it
Set a rate limit or a read-only mode to keep publishing under control

What it gives back to you

You get back a short confirmation in the chat. It usually includes the listing's ID, the type of listing it created, and a list of the relays that accepted it. For Shopstr listings it also tells you whether the storefront update worked. If you ask it to list your items, it gives you a readable rundown of your stalls and products.

Before you start

What you need

The addresses of the Nostr relays you want to publish to
An internet connection that can reach shopstr.store if you want your listings to show up there

Good to know

This server can publish and change your live shop listings, so check what your AI is about to post before you confirm, especially if you turn off the confirm step.
