Apify MCP Servers — by dizzyvinci

Name: Shopify Catalog Monitor
Author: dizzyvinci

Two production-ready Apify Actors available as MCP servers via the Apify MCP Gateway. Free tier users can call them directly from any MCP client (Claude, Cursor, Windsurf, etc.); pay-per-event pricing means you only pay for what you use.

Servers

1. Shopify Catalog Monitor

Track price drops, stock-outs, restocks, and new/removed products across any public Shopify store.

MCP endpoint:

https://mcp.apify.com?tools=dizzyvinci/shopify-catalog-monitor

Apify Store: https://apify.com/dizzyvinci/shopify-catalog-monitor

Tools exposed: shopify-catalog-monitor — polls stores and returns only the diffs (price changes, stock changes, product adds/removes). On first call per store, captures a baseline; subsequent calls return what changed.

Use cases: competitor price intelligence, dropship product research, brand MAP enforcement, restock alerts.

2. US Building Permit Aggregator

Apify Store: https://apify.com/dizzyvinci/building-permit-aggregator

Tools exposed: building-permit-aggregator — returns permits from Chicago, LA, Austin, SF, Seattle, DC, Nashville, Philadelphia, and Boston. All data from official government open-data APIs (Socrata, ArcGIS, Carto, CKAN).
