Sierra Releases Poppy 1.0 With Shopify and Meta Muse Support

What happened
On November 13, 2026, Sierra launched Personal Agent Protocol 1.0, named Poppy. This protocol enables personal AI agents to interact with companies through APIs and websites. Poppy now has automatic support for all Shopify stores and is integrated with Meta's Muse agent. Over 100 companies, including Cisco, Delta Air Lines, Intuit, Salesforce, Twilio, and Zoom, are participating as design partners.
Key details
- Poppy requires companies to publish a poppy.json file at /.well-known/poppy.json over HTTPS.
- Shopify stores in more than 175 countries now automatically support Poppy, with no extra work for merchants.
- Meta's Muse agent checks for Poppy on every site it visits and can use it if present.
- User IDs in Poppy are unique per company and cannot be matched across businesses.
- The implementation kit for companies requires Node 22.18 or later and includes a validator tool.
Why it matters
Shopify merchants and companies using Meta's Muse agent can now offer AI-driven interactions with minimal setup, potentially streamlining customer service and transactions. Businesses can control which capabilities and channels are available to agents, and users retain approval over sensitive actions. Companies adopting Poppy will need to ensure their systems comply with the protocol's requirements, including security rules and user privacy protections.
