Demo I built 5 months ago: https://www.youtube.com/watch?v=02O2OaNsLIk This exposes ecommerce specific tool calls as regular javascript functions as it is more lightweight than going the MCP route.

It's great they are working on standardizing this so websites don't have to integrate with LLMs. The real opportunity seems to be able to automatically generate the tool calls / MCP schema by inspecting the website offline - I automated this using PLayright MCP.
