AI Agent Protocols Explained: MCP vs A2A vs ACP and the Agent Interoperability Stack

MCP and A2A are not rivals — they are complementary layers of the same stack: MCP connects an agent to tools and data, A2A connects agents to each other. Here is the whole interoperability landscape, with ACP, ANP, and AGNTCY put in their place.
