Model Context Protocol is the open standard AI assistants use to connect to outside tools and data. You add the Nice Catalogs server to your assistant once, and from then on it can call these tools whenever a question needs them.

Do I need an account?

Not to look things up. The public tools, which find businesses and read their live prices, need no sign-in at all. To manage your own catalog, your assistant sends you to a Nice Catalogs sign-in page the first time. It uses OAuth, so your password is never shared with the assistant.

How much does it cost?

Looking up businesses is free for anyone. Connecting an assistant to manage your own catalog is part of the Professional plan at $10/month, or $96/year, with a 7-day free trial and $0.00 due today.

Which assistants can connect?

Any assistant or tool that can connect to a remote MCP server over Streamable HTTP, including Claude, ChatGPT, Claude Code, Cursor and VS Code. Paste the server URL where it asks for one. The setup steps above cover the common ones.

Can an assistant delete my products?

Only if you ask it to. Deletion is permanent, so the server refuses unless the assistant passes an explicit confirmation, and the tool tells it to check the exact product with you first. Hiding a product is reversible and is the safer choice for anything sold out or seasonal.

Who shows up in the public directory?

Only businesses that switched on AI Index, which is off until the owner turns it on. They choose which catalogs are included, password-protected catalogs are never listed, and individual customer reviews are never shared.

How do I disconnect an assistant?

Open Settings and go to AI Index. Every assistant connected to your account is listed there with a button to disconnect it, which stops it working immediately.

I am a developer. How do I talk to it directly?

It speaks JSON-RPC over POST at the server URL. A plain GET, from a browser or curl, returns a short JSON description with the supported protocol versions and where the OAuth metadata lives.

Mark the almond croissant as sold out, and put the sourdough on sale for RD$199.

Found both on Pan de Ayer. Here is what I will change:

Almond croissant to out of stock
Sourdough loaf to a sale price of RD$199 (was RD$250)

Shall I go ahead?

Yes, go.

Done. Both changes are live on nicecatalogs.com/pandeayer.

In plain language

Ask the way you would ask a person

No syntax to learn. Your assistant picks the right tool and does the lookup.

Change your catalog

“Add a flat white at $4.50 under Coffee, and hide the pumpkin latte.”

Create, edit, reprice, hide and publish products without opening the dashboard.

Ask about your catalog

“Which of my products have no photo? What do I sell under 500?”

Your assistant reads your real products, hidden ones included, and answers from them.

Find local businesses

“Where can I get sourdough near El Conde, and how much is it?”

Live prices, hours and ratings from businesses that listed themselves. No sign-in needed.

11 tools

What your assistant can do

Two sets of tools behind one URL. The first is open to everyone. The second only appears once an owner has connected their account.

Public directory

No sign-in · read only

Find local businesses

nice_find_businesses

Search the directory by name, kind of business or place. Returns each match with its address, hours, rating and a link to its page.

Get a business profile

nice_get_business

Everything about one business: what it sells, how to find and contact it, opening hours for every day, its rating, and the catalogs it publishes.

Search products and menu items

nice_search_products

Look for a product or dish across every listed business, or within one. Prices and availability are live, kept up to date by each owner.

Read a full catalog or menu

nice_get_catalog

One complete catalog, grouped by category, with every published item, its price and whether it is in stock.

Your account

My account

nice_my_account

Your business, plan, whether AI Index is on, and every catalog you own, drafts included, with its slug and product count.

List my products

nice_my_products

Search the products in one of your catalogs, including the ones hidden from customers, with their prices, categories and visibility.

Create a product

nice_create_product

Add a product with a title, price, category, description and a photo, from a link or an upload. You see it before it goes live.

Asks you first

Update a product

nice_update_product

Change only what you name: price, sale price, stock status, photo, category or text. Everything else stays as it was.

Asks you first

Show or hide products

nice_set_product_visibility

The safe way to take products off the menu when they are sold out or out of season, one or several at a time. Nothing is deleted, and they come back with one message.

Asks you first

Publish or unpublish a catalog

nice_set_catalog_published

Put a whole catalog online, or take it offline at once, without touching its products.

Asks you first

Delete a product

nice_delete_product

Permanent, so it only runs after you confirm the exact product by name. Hiding is usually what you want instead.

Asks you first

What this label means

These tools change your live catalog. Each one tells your assistant to show you the exact change and wait for a yes before it goes through.

Built to be safe

A catalog is a shop window. You hold the keys.

You approve every change

The tools tell your assistant to show you the exact title, price and photo and wait for your yes before anything goes live. Deleting needs a separate, explicit confirmation.

One account, nothing else

A connection acts on the account you signed in with and no other. It cannot see or change anyone else’s catalogs.

Private stays private

Password-protected catalogs never appear in the public directory, and neither do individual customer reviews. Only a business’s overall rating is shared.

Disconnect any time

You sign in with OAuth, so your password is never shared. Every connected assistant is listed under Settings, AI Index, with a button to remove it.
