These buttons fire the same WebMCP tools an external agent would invoke. Use them while connected agents are unavailable.

WebMCP diagnostics

document.modelContext

0 / 10

Discovery check: agents call document.modelContext.getTools(); the browser invokes registered tools by name.

How WebMCP works here

  1. ShopMate calls document.modelContext.registerTool() on mount.
  2. Ten tools are exposed: search_products, filter_products, get_product_details, compare_products, check_stock, add_to_cart, remove_from_cart, update_cart, calculate_cart_total, build_bundle.
  3. An AI agent connected to the page can discover them via document.modelContext.getTools() and call them via executeTool().
  4. Mutating tools pause for the human before changing the cart.
  5. Every call is logged in the Agent Activity panel for visibility.
