LemmeBuyIt is a remote MCP server that gives AI agents access to real-time product search and pricing across 86 major US retailers, Walmart, Target, Home Depot, Best Buy, Macy's, Nordstrom, Zappos, Sephora, Tractor Supply, and 77 more. Approximately 262M products are indexed and refreshed continuously.

Connect once with one-click OAuth (no API keys to copy) and the agent can:

  • Search any retailer's catalog by keyword, GTIN/UPC barcode, brand, or category
  • Look up a specific product by SKU and pull current price, stock status, reviews
  • Compare prices across retailers for the same item
  • Pull weekly price history (up to 2 years) for trend or deal analysis
  • Pull Amazon ASIN price + Buy Box history alongside the cross-retailer data

The server exposes 7 read-only tools. No write access, no destructive operations.

Free tier: search + product lookups. Paid tier: price-history tools.
