Origin & history

first known use2026

Sierra and Meta announced Personal Agent Protocol on October 6, 2026 with Genesys, Instinct, Rocket, Shopify, Stripe, and Walmart as development partners. On October 9, Sierra published draft version 0.1 under the nickname Poppy and named 35 additional design partners, including OpenAI, Visa, Mastercard, PayPal, Bank of America, Cloudflare, Okta, Target, United Airlines, Walmart, and 1Password.

Usage note

Poppy is still a draft rather than a finished, widely deployed standard, so its details and adoption may change. A company publishes a discovery document at /.well-known/poppy.json describing its organization, sign-in methods, APIs, website access, and company agent. The protocol uses OAuth-related standards, scoped session tokens, and DPoP so the company can identify the personal agent and limit what it may read or change. It can expose OpenAPI, MCP, web, or agent-to-agent interfaces under one session. PAP addresses the relationship and authorization between a consumer's agent and a business; MCP connects models to tools, while commerce protocols may focus more narrowly on checkout and payment. PAP can also mean Principal Agent Protocol, an unrelated individual Internet-Draft for cryptographically delegated agent transactions, so the full name matters.
