TL;DR AI
2 min readKey summary
A tutorial shows how to build an MCP-style routed AI agent from scratch.
It covers a modular tool server, dynamic tool discovery, and hybrid routing logic.
The system uses structured planning to choose safe tool calls and limit exposure.
Tool outputs are injected back into context so the final answer can synthesize results clearly.
The pattern aims to make agent systems safer, more scalable, and easier to interpret.
