Google Agent2Agent + (MCP to Tool) in Multi-Agent AI
Google's Agent-to-Agent (A2A) protocol works in harmony with the Model Context Protocol (MCP) to create powerful multi-agent AI systems. While MCP connects AI models to external data and tools through client-server architecture, A2A enables complex multi-turn dialogues between intelligent agents. The new Agent Development Kit (ADK) brings these technologies together, with cross-ecosystem compatibility across 50+ partner companies. This architecture allows agents to communicate autonomously, making independent decisions while maintaining seamless integration with existing systems through agent cards for dynamic discovery.
