Which app do you use?

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http shelfatlas-catalog https://api.shelfatlas.com/api/v1/mcp --header 'Authorization: your-value'Fill in the empty values before running it.
Or copy the settings yourself

Common questions
Is Shelfatlas Catalog safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, Date Math

ShelfAtlas MCP server
Danish grocery catalog and shelf data as MCP tools. Ask *"where is Pepsi Max cheapest right now?"* and get live, structured answers: current offers across every major Danish chain, nearest-store geo search, product name and EAN lookup, and a purpose-built find_cheapest_offers tool. Community shelf-stock signals are included where approved, with confirmation counts.
- Endpoint:
https://api.shelfatlas.com/api/v1/mcp(Streamable HTTP) - Auth:
Authorization: Bearer sa_live_— create a free key at https://app.shelfatlas.com - Docs: https://shelfatlas.com/docs (tools, quotas, error codes)
Tools
| Tool | What it answers |
|---|---|
search_products | Resolve a product name to id + EAN before calling other tools |
get_product_by_ean | Look up a product by EAN-13 barcode |
find_cheapest_offers | "Where is this product cheapest right now?" — live offers, cheapest first, chain resolved |
search_catalog_offers | Catalog offers with price and validity window (live-only by default; chain/EAN/product filters) |
get_stores | Paginated store list, or nearest-first geo search |
list_chains | All retail chains (id, slug, name) |
Claude Desktop
Claude Desktop reaches remote servers through mcp-remote:
{"mcpServers": { "shelfatlas": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.shelfatlas.com/api/v1/mcp"], "env": { "MCP_REMOTE_HEADER_AUTHORIZATION": "Bearer sa_live_ " } } } }
Clients with native Streamable HTTP support connect directly to the endpoint with the Authorization header.
Run locally (stdio)
For clients that only speak stdio, this repository is also a small local server that serves the hosted tools over stdio (Node.js 20+):
git clone https://github.com/SlambertDK/shelfatlas-mcp && cd shelfatlas-mcpnpm ci SHELFATLAS_API_KEY=sa_live_ node index.js
Or with Docker: docker build -t shelfatlas-mcp . and docker run -i --rm -e SHELFATLAS_API_KEY=sa_live_ shelfatlas-mcp.
Listing the tools works without a key; calling them needs SHELFATLAS_API_KEY. server.json is the manifest for the official MCP registry.
