Summary
By 2026, the AI agent ecosystem has converged on a layered protocol stack: MCP for tool access, A2A for agent-to-agent, WebMCP for web interaction, and OSI for semantics, with emerging standards for payments and human interfaces. This stack converts the N-times-M integration problem into N-plus-M, and data platforms are the primary consumers as agents query enterprise data. The historical lesson from data infrastructure is that neutral, layered standards win over proprietary ones.
