Layered Agent Architecture Enables Interoperable MLOps

This article proposes layering the Agent-to-Agent (A2A) protocol with the Model Context Protocol (MCP) to build interoperable, extensible multi-agent systems for MLOps workflows. It demonstrates an Orchestrator, Validation, and Deployment agent pattern that decouples orchestration from execution and uses Agent Cards and MCP-discoverable tools. The approach aims to reduce vendor lock-in and allow teams to add capabilities without rewriting core communication logic.
