Master the Next Generation of Autonomous AI Agents with TypeScript, MCP, and Computer Use!

The era of simple, text-only AI chatbots is over. Modern enterprise applications require autonomous, environment-aware agents capable of querying enterprise databases, executing complex workflows, and navigating web interfaces visually like a human user.

In Volume 25 of the Intelligent Apps with JavaScript & TypeScript series, author Edgar Milvus delivers a masterclass in architecting production-grade agentic systems using Anthropic’s Model Context Protocol (MCP), Playwright, Zod, LangGraph.js, and Next.js.

What You Will Discover Inside:

Model Context Protocol (MCP) Fundamentals: Learn how to build type-safe MCP servers and clients using @modelcontextprotocol/sdk over Stdio and Server-Sent Events (SSE).
Dynamic Tool Discovery & Runtime Validation: Bridge probabilistic LLM reasoning with deterministic code using Zod schema enforcement, stopping model hallucinations before they touch your production database.
Vision-Driven Computer Use: Drive headless browser automation using Multimodal Vision LLMs. Master screen-to-coordinate mapping, Device Pixel Ratio (DPR) scaling, and elementFromPoint hit-testing.
Conquering Complex Web Interfaces: Pierce Shadow DOM boundaries, interpret HTML5 Canvas render buffers using vision models, and traverse deeply nested iFrames seamlessly.
Federated Multi-Agent Systems: Architect Supervisor-Worker agent hierarchies managed by LangGraph.js, complete with parallel tool execution and consensus-building mechanisms.
Enterprise Database Gateways: Connect PostgreSQL, Redis, and Neo4j to AI agents securely through dedicated MCP microservices with parameterized execution and read-only enforcement.
Isolated Code Execution Sandboxes: Safely run untrusted, agent-generated scripts using Node.js V8 execution contexts and hardened, ephemeral Docker containers.
Security & EU AI Act Compliance: Implement real-time PII/screenshot redaction, Human-in-the-Loop (HITL) approval gateways, and tamper-evident, cryptographically signed audit ledgers.

Complete, Production-Grade TypeScript Code

Unlike books that rely on pseudo-code or simplified snippets, this volume provides fully working, enterprise-ready TypeScript code, complete with line-by-line architectural breakdowns, common pitfalls, and practical exercises with detailed instructor solutions.

Build the future of secure, autonomous AI software today.
