Sierra releases Poppy 1.0 as Shopify enables AI agent protocol across stores
Meta’s Muse checks for Poppy first when visiting websites, while Sierra says participation has grown to more than 100 companies.
Sierra announced the release of Poppy 1.0, a standard governing how personal AI agents interact with companies, with Shopify enabling it for every store on its platform. Meta has also made the protocol the first option its Muse agent checks when visiting a website.
Formally named Personal Agent Protocol, Poppy allows businesses to tell agents which company they are dealing with and which tasks are permitted. Customers log in using standard methods and determine their agents’ access, which can cover activities such as order checks and flight bookings.
Sierra said participation had increased by 60 companies to more than 100, including Intuit, Zoom, Salesforce and Delta Air Lines. More than 10 million people have set up Muse.
Merchants on Shopify need not take any steps. Poppy covers an agent’s arrival and self-identification, leaving carts and checkout to Shopify’s existing shopping protocol. Certain actions require permission from the shopper.
At Mercury, agents can retrieve account balances and initiate payments, though account approval requirements still apply. Turkish Airlines supports searches for fares and business-class upgrades; customers must approve upgrades before making payment.
Despite the 1.0 label, Poppy’s specification remains a draft, with revisions permitted that could make existing implementations stop working. The protocol was initially introduced by Sierra and Meta in October.
