storedata

storedata is a small local bridge to the hosted HasData Shopify MCP server, which returns public Shopify storefront data as JSON. Point it at a storefront URL and it lists that store's collections — id, title, handle, description and image for each one — and it pulls the store's products, optionally narrowed to a single collection by handle. Both reads page with a limit (up to 250) and a page number.

The bridge keeps no catalogue of its own. It answers the tool list locally, exactly as captured from the live endpoint, and forwards each tool call upstream, returning whatever comes back untouched. The captured surface is two read-only fetches over public storefronts: there is no cart, checkout, order or payment tool in it, and no store-owner contact data is returned.

Tools

• hasdata_shopify_collections_getCollections — list a storefront's collections. Required: url (the Shopify store URL). Optional: limit and page for pagination. Returns each collection's id, title, handle, description, image and timestamps. The returned handles feed the products tool when you want one category at a time.
• hasdata_shopify_products_getProducts — pull a storefront's products. Required: url. Optional: collection (a collection handle to filter by), plus limit and page. Returns product id, title, handle, vendor, product type, tags, body HTML, images, variants with prices, SKUs and inventory status, and timestamps.

Configuration

• HASDATA_SHOPIFY_MCP_URL (optional) — override the upstream endpoint. Defaults to https://mcp.hasdata.com/mcp?apis=shopify. (The override hook is this rebuild's own labelled reconstruction.)
• HASDATA_API_KEY (optional) — when set, every upstream request carries an x-api-key: <key> header, for the caller's own HasData API key. When it is not set, no key header is sent. (The header name and the env name are pinned by the original's registry record; forwarding the key from this env var is a labelled reconstruction — the original surface was captured keyless.)

Forwarding mechanics

On the first tool call the client opens a streamable HTTP session upstream: a JSON-RPC initialize request (protocolVersion 2025-03-26, clientInfo name storedata), then a notifications/initialized notification, then the tools/call request carrying the caller's arguments unchanged. When the upstream answers initialize with an Mcp-Session-Id header, that value rides on every later request of the session, which is reused for the life of the process. Replies may arrive as plain JSON or as server-sent events; both are read.

Successful upstream results pass through verbatim, including any isError flag the upstream sets. Failures — a JSON-RPC error, a non-2xx status, an unreadable response, or a request that cannot be completed — come back as an isError result whose text starts with storedata error: (this rendering is this rebuild's own labelled reconstruction).

CLI

Each tool is also a subcommand taking one JSON argument string:

npx @reneturcios/storedata hasdata_shopify_collections_getCollections '{"url":"https://b2bdemoexperience.myshopify.com"}'
npx @reneturcios/storedata hasdata_shopify_products_getProducts '{"url":"https://b2bdemoexperience.myshopify.com","collection":"frontpage"}'
npx @reneturcios/storedata --version

Exit codes: 0 on success, 1 on an isError result, 2 on a usage error.

MCP server

npx -y @reneturcios/storedata mcp

MCP client config:

{
  "mcpServers": {
    "storedata": {
      "command": "npx",
      "args": ["-y", "@reneturcios/storedata", "mcp"]
    }
  }
}

Docker

docker run -i ghcr.io/cloudcorprecords/storedata
docker run --rm ghcr.io/cloudcorprecords/storedata --version

The container's default command is mcp, so the first form is a stdio MCP server; any other arguments reach the CLI normally.

Development

npm install
npm run build
npm test
npm run dev

The test suite runs entirely against a stubbed JSON-RPC upstream — no live network calls.
