Open-source MCP server that lets AI assistants shop via Google's UCP
Exposes the entire UCP shopping flow as discrete MCP tools (ucp_discover, checkout create/update/fulfillment/complete), which is smart because agents need typed, deterministic primitives not brittle browser hacks. It’s practical — pip installable with a CLI entrypoint and basic tests — so you can prototype agent-driven purchases fast. What would push it higher: richer merchant adapter examples, more end-to-end payment/edge-case docs, and clearer security/payment handling guidance.
