Core Concepts - A2A (Agent2Agent) enables AI agents to collaborate without sharing internal data, thoughts, or tools [1][2] - MCP provides agents with access to tools, while A2A facilitates agent-to-agent communication and teamwork [1] - A2A agents can be modeled as MCP resources using AgentCards [2] Functionality and Benefits - A2A supports secure collaboration, task and state management, UX negotiation, and capability discovery [3] - A2A allows agents from different frameworks to work together [3] - Remote Agents supporting A2A must publish a JSON Agent Card detailing their capabilities and authentication [2] Industry Implications - Standardizing Agent-to-Agent collaboration is beneficial, similar to MCP's role in Agent-to-tool interaction [3] - Clients can use Agent Cards to find the best agent for a task [3]
