The Model Context Protocol (MCP) is quickly moving beyond its original role as a standardized way for AI applications to connect with external tools and data. The latest MCP specification makes the protocol stateless, cacheable, routable through standard HTTP infrastructure, and better suited for enterprise authorization, while the project's latest roadmap explicitly prioritizes agent identity and enterprise-ready security. For leaders, the more important development is what organizations are beginning to build around MCP. As MCP patterns become infrastructure for agentic systems, three useful architectural patterns are emerging: Tool Mesh, Agent Mesh, and Control Plane. These are not official MCP protocol classifications. They are practical architectural patterns for understanding how MCP can create value at increasing levels of complexity.AI & Data Science · Sep 16, 2026
