Sierra shipped Poppy 1.0 and Shopify turned it on for every store.
Every Shopify store now publishes a Poppy file with no extra setup, according to Sierra. Shopify powers businesses in more than 175 countries, Sierra said, and every store already supports Universal Commerce Protocol by default. The split is clean. UCP runs find, cart and checkout while Poppy handles identity, permissions and store to agent chat through UCP Ask. Shopify co-authored the commerce extension, which lets shoppers check out as guests or signed in and forces the agent to ask before sensitive moves.
Muse now looks for Poppy first on every site it visits.
That default matters because Meta owns Muse, and Sierra said Poppy is now on for everyone who uses it. The Next Web calls Sierra the startup behind the standard, a useful reminder that a vendor is driving what is pitched as open. Sierra added 60 design partners for a total of more than 100, including Affirm, Delta Air Lines, Intuit, Salesforce and Zoom, according to the company.
Mercury lets banking customers check balances, review transactions, categorize spending and start payments inside approval policy, Sierra said. Synchrony is testing financing and rewards inside agent shopping across more than 500,000 merchant locations. Turkish Airlines lets agents check fares, flight status and bookings by reference and surname, plus Miles&Smiles business upgrades with customer approval. Full purchase inside the chat is still to come.
Poppy 1.0 is built on MCP, OpenAPI and UCP with OAuth for user control, Sierra said. Companies can adopt in stages and validate with Sierra implementation kit. That matters because scraping breaks at login, checkout and consent, and Poppy moves those steps into declared permissions. That sell-to-bots shift now has a default path into checkout.
If you run on Shopify, you are already live whether you planned for agent traffic or not.
