The Model Context Protocol (MCP) is quickly becoming the standard interface between AI agents and external capabilities. But building production-grade MCP servers today still requires gluing together transports, validation, error handling, observability, and auth — all from scratch.

Vurb.ts changes that.

Why Vurb.ts

Vurb.ts is the AI-First Developer Experience for the Model Context Protocol. It introduces the MVA (Model-View-Agent) architectural pattern — a paradigm designed specifically for agentic workloads — alongside a rich toolkit that lets you ship production-ready MCP servers in minutes instead of days.

What you get out of the box

Capability	What it does
Presenters	A deterministic View layer for AI agents — structure perception, consolidate actions, and apply cognitive guardrails.
Zod-first tools	Define tool schemas with Zod; input validation, type inference, and documentation are derived automatically.
Middleware pipeline	Auth, rate-limiting, logging, and custom logic — composable and reusable.
Error self-healing	Structured error responses that guide the agent to fix and retry, rather than fail silently.
Governance	Capability lockfiles, contract diffing, blast-radius analysis, and zero-trust attestation.

The MVA Pattern

Traditional MVC was designed for human-driven request cycles. Agent-driven workflows have fundamentally different needs:

• Agents don't render HTML — they consume structured perception packages.
• Agents don't click buttons — they select affordances exposed by the server.
• Agents can hallucinate — cognitive guardrails are a first-class concern.

The Model-View-Agent pattern addresses all three. The Presenter replaces the controller+view responsibilities and acts as the deterministic bridge between your business logic and the non-deterministic agent.

Getting started

Install the framework and create your first server in under a minute:

npx mcp-fusion init my-server
cd my-server
npm run dev

Then connect it to Claude Desktop, Cursor, Windsurf, or any MCP-compatible client.
