Beyond MCP: Why Simplicity Is Winning the AI Agent Integration War

MCP promised a unified protocol standard for AI agents but faces fundamental challenges with context bloat and reliability that simpler approaches overcome.

This shift signals that operational simplicity and token efficiency matter more than architectural elegance in the AI era.
