MCP 1.5 Architecture: How AI's Universal Protocol Redefines Enterprise Context Security

As autonomous AI agents embed deeper into enterprise infrastructures, bi-directional communication between LLMs and internal data stores demands a single standard. An in-depth analysis on how Model Context Protocol solves context window bloat and zero-trust edge authorization.

“Transitioning from custom API wrappers to a unified MCP specification slashes agent integration timelines by up to 70% in Enterprise environments.”
