Agentic AI Systems: Build Multi-Agent Workflows with LangChain, MCP, RAG & Ollama
(A Practical Guide to Local LLM Orchestration, Retrieval-Augmented Generation, and Autonomous Agents)

Unlock the power of local LLMs, agentic AI architectures, and multi-agent orchestration with this hands-on guide designed for developers, AI engineers, and system architects building intelligent applications beyond the cloud. In an era where data privacy, autonomous workflows, and cost-effective deployments are critical, this book offers a production-ready blueprint using LangChain, Model Context Protocol (MCP), Retrieval-Augmented Generation (RAG), and Ollama.

Whether you're designing AI copilots, deploying autonomous agents, or developing secure on-premise AI systems, this guide helps you go from concept to execution with confidence.

• Set up a complete agentic AI stack with LangChain, LangGraph, MCP, and Ollama

• Run private LLMs like Llama 3 and Mixtral with full control using Ollama

• Fine-tune models with LoRA/QLoRA for domain-specific applications

• Design and orchestrate multi-agent systems using LangGraph and graph-based coordination

• Build robust Retrieval-Augmented Generation pipelines using FAISS and Chroma

• Implement secure message-passing and streaming using MCP

• Handle authentication, observability, and compliance (GDPR, HIPAA, SOC 2)

• Deploy agents with Docker, Kubernetes, and scalable CI/CD pipelines

• AI engineers and backend developers working with LLMs and LangChain

• Security-conscious teams needing private and auditable AI workflows

• DevOps and MLOps professionals deploying containerized AI systems

• Researchers and tech leads building autonomous agent systems

• Anyone interested in real-world agentic AI with local deployment capabilities

Unlike cloud-reliant AI books or overly academic texts, Agentic AI Systems delivers actionable blueprints for building and deploying real systems on local infrastructure. You'll explore hands-on code, architecture diagrams, and reusable patterns that scale from laptops to clusters. No fluff-just proven strategies and reproducible workflows grounded in current LLM capabilities.
