Local AGENTIC AI with OLLAMA: Build Private Agents LLMs, Tool Use, RAG, MCP, Memory, and Automation

What if your AI agents could run locally, work with your own data, use real tools, and operate without sending every interaction to a cloud service?Local Agentic AI with Ollama is a practical guide to building private, tool-using AI agents with local language models.Starting with the fundamentals of agent architecture, you'll learn how to turn a local LLM into a system that can reason through tasks, call tools, retrieve information, maintain memory, interact with files and APIs, and execute controlled workflows.Inside the book, you'll learn how to: - Run and manage local LLMs with Ollama - Build the core agent loop and execution state - Implement tool calling and function execution - Validate model-generated arguments and control tool permissions - Build short-term and long-term agent memory - Create Retrieval-Augmented Generation (RAG) systems - Give agents controlled access to files, web resources, and APIs - Connect agents to external capabilities with MCP - Build multimodal local AI agents - Design multi-agent systems and specialized agent workflows - Automate multi-step tasks with bounded autonomy - Protect agents against prompt injection and unsafe tool execution - Add testing, logging, observability, and performance monitoring - Build a complete private local AI workspaceRather than treating an AI agent as simply a chatbot with a larger prompt, this book approaches agentic AI as a software engineering problem. You'll learn how models, tools, state, memory, retrieval, permissions, and execution controls fit together to create reliable systems.Whether you are experimenting with local LLMs, building AI-powered applications, or looking for greater control over your AI workloads and data, this book provides a hands-on path from a basic local model to a practical agentic AI system.
