LemMeBuyIt tutorial: live retail prices via one MCP URL
A 10-minute video shows connecting ChatGPT, Claude, Cursor and other MCP clients to live retail prices and price history via one URL.
New on our YouTube channel: a 10-minute, step-by-step tutorial on adding live retail prices to Claude, Cursor, Grok Bot, ChatGPT or any MCP agent. The short version: it's one URL. https://mcp.lemmebuyit.com/mcp • Claude: add it as a custom connector and sign in with OAuth • ChatGPT: LemMeBuyIt is an approved ChatGPT app • Cursor: five lines in mcp.json • Grok Bot and any other MCP client: same URL, same OAuth sign-in Why it matters: a model's prices are frozen at training time. This morning's Live Platform Pulse on http://lemmebuyit.com showed 292M+ ASIN mappings, 463M+ price-history records and 7.3M+ products refreshed in the last 24 hours, across 100+ US retailers. Once connected, that's what your agent answers from. The video also walks through five example queries, Free vs Standard vs Pro, and a mini price-compare agent you can build with a single instruction block.
