LMK MCP: cross-merchant prices and price history for your AI app

Add LMK shopping search to Claude, ChatGPT or Cursor

1. 1Click Connect LMK free. There's no sign-in, so its tools are ready at once.
2. 2None of LMK's 13 tools place orders; they search and price. Switch off the demand-signal tools, `get_trending_products` and `get_popular_products`, if you want your AI app kept to search and price checks.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Ask your AI app whether a pair of noise-canceling headphones is at its 90-day low, then open Activity to see the `get_price_history` call.
