Architecting Agentic MLOps: A Layered Protocol Strategy with A2A and MCP
"Robust, interoperable agent automation systems can be engineered by layering an Model Context Protocol (MCP) with Agent-To-Agent (A2A). These protocols can be used for automating an MLOps workflow using agents. A2A provides the communication bus, and MCP acts as a universal language for agent capabilities. A layered agent-based approach leads to more extensible systems, where new capabilities can be added without changing the core communication logic in the agentic era."
"The reusable template presented in the article used a multi-agent system design approach, providing an architectural pattern for decoupling orchestration logic from execution logic, a principle used in scalability. This pattern provides a deliberate structure for moving beyond simple, monolithic agents toward collaborative systems. Using a layered A2A-MCP pattern is not confined to MLOps. Its principles extend across any domain where dynamic collaboration and adaptable access to capabilities are crucial for building the next generation of intelligent systems, enabling AI agents to move from isolated tasks to coordinated intelligence and unlocking unprecedented levels of automation and adaptability."
"As the software industry enters the agentic era, developers and architects face a familiar challenge. Just as the rise of microservices required standardized communication patterns, such as REST and gRPC, the proliferation of specialized AI agents requires a robust framework for them to discover, communicate, and collaborate effectively."
Layering Agent-to-Agent (A2A) with Model Context Protocol (MCP) creates a communication bus paired with a universal capability language, enabling interoperable agent automation. A layered agent architecture decouples orchestration logic from execution, allowing new capabilities to be added without changing core communication pathways. A reusable multi-agent design template supports scalable systems by separating coordination from task execution and encouraging collaboration among specialized agents. These principles apply beyond MLOps to any domain requiring dynamic collaboration and adaptable capability access, enabling transition from monolithic systems to coordinated, evolving agent-driven operations.
