Architecture Deep Dive: MCP-Style Routed AI Agents

New open-source blueprint for building modular AI agents with:
• Tool Server — Central registry exposing tool metadata
• Hybrid Router — Keyword heuristics + LLM reasoning for dynamic tool selection
• Planner — Breaks tasks into executable steps
• Executor — Runs tool calls with context injection

Key metrics: 75% cost reduction vs monolithic models. Dynamic capability exposure improves both efficiency and safety.

Stack: The tutorial uses gpt-4.1-mini but is model-agnostic. Open source. MIT-licensed approach.
