Overview

AI-generated overview

A remote Apify MCP server that monitors public Shopify stores and reports price changes, stock-outs, restocks, and added or removed products.

What you can do
Monitor Shopify store catalogs for price changes, stock-outs, restocks, and new or removed products or variants, reporting only the differences between runs after an initial baseline snapshot.
When to use it
Useful for competitor price monitoring, dropshipping and product research, minimum-advertised-price enforcement, and deal or restock alerts on public Shopify stores.
Requirements
A remote endpoint at mcp.apify.com with OAuth authentication. An Apify account is implied by the pay-per-event pricing. Target stores must expose a public products.json endpoint.
Before you install
Priced pay-per-event: you pay for stores checked and changes detected, with no subscription. Stores that disable products.json are skipped. The first run only captures a baseline, so changes appear from the second run onward.

Installation

In SourceWeft

  1. Open Shopify Catalog Monitor in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.dizzyvinci%2Fshopify-catalog-monitor/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Shopify Catalog Monitor — Price & Stock Change Alerts

Track price drops, stock-outs, restocks, and new or removed products across any public Shopify store. Schedule it daily or hourly and get only the diffs — not a giant dump you have to compare yourself.

Who uses this

  • Competitor price monitoring — watch rivals' Shopify stores and react to every price move.
  • Dropshipping & product research — catch new product launches and bestseller restocks early.
  • Brand / MAP enforcement — detect when a reseller breaks minimum-advertised-price.
  • Deal & restock alerts — know the moment a sold-out item is back in stock.

How it works

The Actor reads each store's public /products.json endpoint (no login, no scraping of rendered pages), stores a snapshot, and on every subsequent run reports what changed since last time:

Change typeMeaning
price_changedA variant's price moved (includes from / to)
out_of_stockA variant went unavailable
back_in_stockA variant became available again
product_addedA new product appeared in the catalog
product_removedA product disappeared from the catalog
variant_addedA new variant (size/color) was added

Input

FieldTypeDescription
storesarray of stringsStore domains or URLs, e.g. gymshark.com
maxProductsPerStoreintegerCap on products fetched per store per run (default 5000)
onlyReportChangesbooleanOutput only diffs (default true)

Output

Each detected change is one dataset record:

json
{ "store": "https://gymshark.com", "detectedAt": "2026-06-01T12:00:00.000Z",  "type": "price_changed", "productId": "123", "handle": "training-shorts",  "variant": "M / Black", "from": "38.00", "to": "30.00" }

The first run of a store captures a baseline (no diffs); changes start on the second run — so schedule it and let it work.

Notes

  • Only works on stores that keep /products.json public (most do; some large brands disable it — those are skipped with a notice).
  • Priced pay-per-event: you pay for stores checked and changes detected. No subscription.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
