Insurify Joins Sierra-Led Poppy Protocol for AI Agents
Insurify, a leading online insurance marketplace, announced it is joining Sierra and other technology leaders as an early design partner for the AI Personal Agent Protocol, known as Poppy. Insurify will help shape standards for shopper consent, coverage transparency, and carrier protections within the protocol. The company aims to ensure that AI agents used for insurance shopping preserve critical coverage information, such as limits, deductibles, and eligibility requirements, while maintaining privacy and security. Insurify already offers personalized car insurance quotes via a ChatGPT plugin, and this partnership advances its objective of trustworthy AI-powered insurance shopping. The protocol, initiated by Sierra, seeks to establish a framework where consumers approve agent access, agents identify themselves, and companies set boundaries. Insurify will advocate for insurance-specific protections to prevent unauthorized automated quoting and ensure carrier attribution.
- Insurify joins Sierra and other tech leaders as early design partner in the Poppy protocol.
- Poppy is a proposed AI Personal Agent Protocol for consumer-agent interactions.

Meta, Walmart, Sierra launch personal agent protocol
Meta and Sierra, led by chairman Bret Taylor, have announced the Personal Agent Protocol (PAP) for AI-agent interactions with businesses, with initial partners including Walmart, Shopify, Stripe, Genesys, Rocket, and Instinct. PAP defines three access levels (guest, read-only, and write access) built on OAuth and places businesses in charge of vouching for consumer AI agents, differentiating it from rival designs by Visa, Mastercard, and AI platforms. The protocol aims to control customer data and liability in agentic commerce, with future implications for agentic payments. However, PAP is still in early stages: no specification, license, or governing body exists, and payments are not yet supported. Version 0.1 is expected this month, with payments and fine-grained permissions planned later. Notably, Amazon, Google, and OpenAI are absent, reflecting Meta's competitive positioning, especially after Amazon blocked Meta's Muse agent. The protocol competes with OpenAI's Agentic Commerce Protocol and Google's Universal Commerce Protocol.
- Meta and Sierra announced the Personal Agent Protocol (PAP) on October 6, with initial partners including Walmart, Shopify, Stripe, Genesys, Rocket, and Instinct.
- PAP defines three access levels—guest, read-only, and write access—built on OAuth.
- PAP places businesses in charge of vouching for consumer AI agents, differentiating it from rival designs by Visa and Mastercard.
