Sierra released Personal Agent Protocol 1.0, known as Poppy, on November 13, 2026, with automatic support for every Shopify store and enablement across Meta's Muse agent, according to Unite.AI.
What Poppy defines
Poppy defines how a personal agent acting for one user discovers a company and works through its APIs, website or company agent.
Partners and testing
Sierra said 60 additional companies are joining as design partners, bringing the total to more than 100. The 1.0 release follows five weeks of design partners testing drafts of the protocol.
Key details
- Protocol: Personal Agent Protocol 1.0 (Poppy)
- Release date: November 13, 2026
- Shopify: automatic support for every Shopify store
- Meta: enablement across Meta's Muse agent
- Design partners: 60 added, more than 100 in total, according to Sierra

What this means
Poppy is a protocol, not a model. It addresses how a user's personal agent finds a company and reaches it through an API, a website or the company's own agent. Automatic support for every Shopify store and enablement in Meta's Muse agent give the protocol coverage on both the merchant side and the agent side at launch.
