Practical tRPC and Vercel MCP Development: Build Modular, Testable Commands and Automations with TypeScript, Jest, Playwright, and Semantic Versioning

By Avis Gabe

Practical tRPC and Vercel MCP Development tackles a problem every modern team feels: automation sprawl. Scripts multiply. CLIs drift. ChatOps and AI agents call slightly different code paths-and bugs creep in. This book shows a faster, safer way to ship: define your command logic once, then expose it everywhere with TypeScript, tRPC, and Vercel MCP.

You'll learn a compact, production-ready system for building modular, testable commands that serve CLI, HTTP, ChatOps, and AI agents from the same source of truth. Using Zod for schemas, Jest and Playwright for tests, and tsup with semantic versioning for packaging, you'll create commands that are easy to discover, trust, and extend. Real labs walk you through a CI/CD helper (Octokit/GitHub Actions) and a ChatOps bot for Slack or Discord-both powered by the exact same tRPC procedures and MCP tools-then deploy cleanly to Vercel with monitoring and release automation.

What you'll gain

A repeatable architecture for type-safe commands that power CLI, ChatOps, and AI agent workflows via tRPC + Vercel MCP

Schema-first reliability with Zod: validated inputs/outputs, consistent errors, predictable responses

Packaging that scales: dual ESM/CJS builds with tsup, export maps, changelogs, and semantic versioning

Confidence at speed: unit tests (Jest), API/CLI tests (Playwright, execFileSync), and GitHub Actions gating

Operational clarity: TRPCError patterns, structured logging, observability, performance budgets, and profiling (0x, Node --cpu-prof, Benchmark.js)

Security and resilience: 2FA/provenance for npm, sane defaults for environments, and production-grade error handling

Hands-on practice: build a GitHub Actions CLI and a Slack/Discord ChatOps bot; schedule and orchestrate commands; host on Vercel

Team-friendly discoverability: self-documenting tools, rich help text, and MCP discovery metadata

If you want faster releases without sacrificing safety-if you need one consistent command surface for Node.js 20+, Next.js APIs, CI pipelines, Slack/Discord, or agent frameworks-this is the playbook. Build once. Ship everywhere. Get the architecture, patterns, and working examples that turn scattered scripts into a coherent, scalable system.
