Description

Agent Communication Protocol (ACP) is an open standard created to solve interoperability challenges between AI agents operating across different frameworks and platforms. The protocol establishes a common communication layer using REST-based APIs, enabling agents to exchange information through familiar HTTP patterns. Organizations can use ACP to connect agents regardless of the underlying technology stack, reducing the need for custom integrations and framework-specific connectors. It supports both real-time and asynchronous communication models, making it suitable for simple requests as well as long-running workflows. ACP accommodates a wide variety of content types through MimeType-based messaging, allowing agents to share text, multimedia, and specialized data formats. The protocol also enables agent discovery, including scenarios where agents are offline or operating in disconnected environments. Developers can interact with ACP using standard HTTP tools or leverage official Python and TypeScript SDKs for faster implementation. By standardizing communication, ACP simplifies the development of multi-agent systems that collaborate across applications, departments, and organizations. The project is governed as an open initiative within the Linux Foundation ecosystem, encouraging community-driven innovation and broad industry adoption.

Description

Google has introduced the Agent Payments Protocol (AP2), a collaborative open protocol developed with over 60 diverse companies in payments, fintech, and technology, including Mastercard, PayPal, Adyen, Coinbase, and Etsy, aimed at facilitating secure transactions led by agents across various platforms. This new protocol builds upon previous open standards such as Agent2Agent (A2A) and the Model Context Protocol (MCP) to ensure that when an AI agent processes a payment on behalf of a user, it adheres to three essential criteria: authorization, to confirm that the user has explicitly consented to the specific transaction; authenticity, to verify that the purchase intended by the agent aligns with the user's actual intent; and accountability, to maintain transparent audit trails and assign responsibility in the event of any errors or fraudulent activities. In order to uphold these standards, the protocol incorporates mandates, which are cryptographically signed digital contracts that are supported by verifiable credentials, ensuring a high level of security and trust in agent-led transactions. The implementation of AP2 represents a significant advancement in the realm of digital payments, aiming to enhance user confidence in automated financial interactions.
