A2A, MCP, Kafka and Flink: The New Stack for AI Agents
A2A, MCP, Kafka, and Flink form a foundational stack for scalable, collaborative AI agent ecosystems. A2A standardizes how agents communicate with one another, while MCP defines how they access tools and external context. Kafka acts as the event-driven messaging backbone, and Flink enables real-time processing of those events—together enabling agents to interact, reason, and act with resilience and coordination across complex systems.
