Agentic AI Engineering is a production-grade engineering resource for building modern agentic AI systems with LangChain, LangGraph, RAG, MCP, local models, and deployable Python services.
The repository leads toward the architecture implemented in Chapter 5: a multi-node LangGraph assistant connected to a standalone MCP server, with intent routing, tool execution, response summarization, email tooling, math tools, automated tests, and GitHub Actions CI. Earlier chapters build the required layers underneath it: provider abstraction, LCEL orchestration, vector retrieval, memory, ReAct agents, router graphs, sequential workflows, multi-agent collaboration, and human-in-the-loop control.
This is not a beginner chatbot walkthrough. It is a structured engineering path for developers building systems that need state, tools, routing, retrieval, observability, modularity, and model-provider flexibility.
What You'll Build
- Multi-node LangGraph assistant with router, execution, summarization, and conversation nodes.
- MCP tool server exposing isolated math and email tools over a decoupled server boundary.
- Tool-using ReAct workflows that call external capabilities through typed tool contracts.
- RAG pipelines using vector stores, embeddings, retrieval chains, and local document context.
- Provider-flexible LLM interfaces across OpenAI, Gemini, and Ollama.
- Agent routing systems for sequential, router-based, ReAct, and multi-agent workflows.
- **Human-in-the-loop executio
