𝗧𝗵𝗲 𝗡𝗲𝘄 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹 𝗪𝗮𝗿𝘀: 𝗪𝗵𝘆 𝗠𝗖𝗣 𝗮𝗻𝗱 𝗔𝟮𝗔 𝗠𝗮𝘁𝘁𝗲𝗿 𝗡𝗼𝘄 We're at a strategic inflection point in AI infrastructure. Two protocols—𝗠𝗖𝗣 and 𝗔𝟮𝗔—are quietly redrawing the map of how tools, data, and agents interact. If you’re building, investing, or betting on where the AI stack goes next, pay attention. Why? Because just like the protocol wars of the late '90s, what looks like low-level plumbing today will shape who owns the user, the interface, and the economic power tomorrow. 𝗣𝗿𝗶𝗺𝗲𝗿: 𝗠𝗖𝗣 𝘃𝘀 𝗔𝟮𝗔 (📌 𝗦𝗮𝘃𝗲 𝘁𝗵𝗶𝘀) 𝗠𝗖𝗣 (𝗠𝗼𝗱𝗲𝗹 𝗖𝗼𝗻𝘁𝗲𝘅𝘁 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹) Think: “HTTP for AI agents” Designed for: Agent ↔️ Tool interaction Format: Structured, stateful function calls Use case: Plugging AI into existing apps, data, APIs Analogy: Like Zapier for AI, but smarter and runtime-aware 𝗔𝟮𝗔 (𝗔𝗴𝗲𝗻𝘁-𝘁𝗼-𝗔𝗴𝗲𝗻𝘁) Think: “TCP/IP for multi-agent systems” Designed for: Agent ↔️ Agent communication Format: Natural language prompts + shared context Use case: Choreographing workflows across domains Analogy: Microservices, but everyone speaks English They’re not rivals. They’re layered. And together, they’re creating a stack where agents can call tools (MCP) or collaborate with other agents (A2A)—a foundational shift in how work gets done. Google just joined the A2A bandwagon. OpenAI, Anthropic, and others have embraced MCP. We're watching consolidation around de facto standards. That alone is enough to raise eyebrows. 𝗙𝗶𝗻𝗮𝗹 𝗧𝗵𝗼𝘂𝗴𝗵𝘁: 𝗔𝗣𝗜𝘀 𝗔𝗹𝗹 𝘁𝗵𝗲 𝗪𝗮𝘆 𝗗𝗼𝘄𝗻 “𝘉𝘦 𝘤𝘢𝘳𝘦𝘧𝘶𝘭 𝘸𝘩𝘢𝘵 𝘺𝘰𝘶 𝘦𝘹𝘱𝘰𝘴𝘦—𝘢𝘯𝘥 𝘸𝘩𝘢𝘵 𝘺𝘰𝘶 𝘥𝘰𝘯’𝘵.” — Uri Maoz, WireMock If your app has an API, it’s already on the menu for agents. The decision is whether you serve it up intentionally—or let someone else mediate that access and own the experience. This is bigger than features. This is about control.
