Nacos 3.2 expands beyond a micro‑service registry to become a unified AI asset governance platform, introducing AI Registry, MCP Registry, a three‑layer Skill security sandbox, Copilot assistance, and A2A protocol integration for seamless enterprise AI adoption.
This article explains the challenges of traditional point‑to‑point AI agent communication, introduces the A2A protocol and its limitations, and details how combining A2A with MQTT via Tencent Cloud TDMQ creates a dynamic, loosely‑coupled, and scalable solution with practical SDK examples and real‑world case studies.
The article explores Google’s A2A protocol and the MCP framework, comparing their roles as complementary gears that enable AI agents to collaborate, extend capabilities, and interact with external resources, illustrated with a smart‑customer‑service scenario and future outlooks.
Google’s open‑source A2A (Agent‑to‑Agent) protocol, unveiled at Google Cloud Next 2025, defines a standardized, secure, Web‑based framework that lets heterogeneous AI agents discover each other, negotiate interactions, and manage cross‑agent tasks, supporting multimodal communication, long‑running jobs, and push notifications.
