Claude AI for Developers: API, Agents, MCP & Code

Every tutorial on building AI agents skips the one part where it actually breaks once real users show up.You can copy a working demo in an afternoon, but shipping something real to production is an entirely different story. The moment you actually need persistent memory, real tool calls, and a genuine production deployment, most guides go completely quiet.Claude AI for Developers is the technical guide that finally picks up right where the official documentation always stops. Eighteen chapters walk you from your first API call to production ready agents built on the Agent SDK and MCP. Claude Code receives a full, dedicated treatment as well, covering everything from a first install to CI/CD automation at scale.Inside this hands-on, practical guide written specifically for working engineers, you will learn exactly how to: - Send your first Claude Messages API call and understand exactly what happens inside the tool use loop- Write custom MCP servers your entire engineering team can safely connect to, reuse, and actually trust- Configure Claude Code with memory, fine-grained permissions, and hooks that genuinely hold up under real use- Deploy autonomous agents behind real sandboxing and credential proxies actually built for serious production traffic- Coordinate subagents and full agent teams on real projects without ever losing control of your cost- Automate code review, testing, and pull requests using headless mode and real CI/CD pipelines end to end- Scale Claude safely across your entire engineering organization with gateways, spend limits, and real governanceStop talking about AI agents in your next standup and finally become the developer who actually ships them into production.
