Agentic Web Protocol Scout

Open standard letting websites and web apps expose tools and data to AI agents in the browser — bringing MCP-style integrations to the open web.

Universal open standard for agentic commerce developed by Google with Shopify, Etsy, Wayfair, Target, Walmart and 20+ industry partners.

First agentic commerce protocol co-developed by OpenAI and Stripe, enabling AI agents to complete purchases seamlessly through ChatGPT.

Cryptographic identity for AI agents on the open web. Agents sign requests with HTTP Message Signatures (RFC 9421) so sites can tell a legitimate agent from a scraper — the gate every agent passes before it can reach a merchant.

Open standard for agents built by different vendors to discover each other, delegate tasks and coordinate work. Announced by Google, donated to the Linux Foundation in June 2025; UCP builds on it.

Identity and consent for personal agents acting on a customer's behalf. Agents sign every request so a business knows which agent is calling; customers approve scoped permissions on the business's own login page. Open-sourced by Decagon; builds on A2A.
