    MCP, A2A, and Beyond

    Understand MCP, A2A, and the protocol ecosystem that enables agent interoperability and tool integration.

    "MCP is the USB-C of AI—it lets any agent plug into any tool through a single standard interface."
    — AI Agent Automations

    The agent protocol landscape has standardized rapidly. MCP (Model Context Protocol) provides universal tool integration—"USB-C for AI"—backed by Anthropic, OpenAI, and Google via the Linux Foundation. A2A (Agent2Agent) enables agent-to-agent communication. Understanding when to use each, how they complement each other, and how to build or use MCP servers is essential for production agent systems.
