Agent2Agent (A2A) Protocol is an open protocol developed by Google to facilitate collaboration among AI agents, allowing them to work together while retaining autonomy and privacy. Unlike the Model Context Protocol (MCP) by Anthropic, A2A emphasizes agent collaboration across different tasks, such as managing emails or maintaining systems like Salesforce. It integrates with existing IT standards and includes security features aligned with OpenAPI, supporting long-running tasks and various communication modes like text, audio, and video streaming. A2A has garnered support from over 50 technology partners and service providers, enhancing its market presence. It employs a three-prong communication system to manage tasks, enabling agents to advertise capabilities, complete tasks with defined outputs, and collaborate effectively. Credal, an AI product, is A2A-ready, offering a comprehensive environment for AI governance and multi-agent workflows, positioning itself as more robust than Google’s own Google Agentspace by focusing on custom, first-party agent development.
