What is Poppy 1.0?
Sierra has released version 1.0 of the Personal Agent Protocol, or Poppy, a standard that defines how personal AI agents communicate with companies. The goal is a common language for agents when they access a site or service.
Who has adopted it?
Shopify has turned the protocol on for every store. Meta's Muse agent now looks for it on every site. According to Sierra, more than 100 companies have signed up.
Why it matters
AI agents increasingly act on users' behalf, from shopping to information requests. A shared protocol aims to prevent every company from building separate integrations for agents and to route this traffic through a single standard. Poppy reaching 1.0 shows the standard is moving from experimental to commercial use.
