Overview

AI-generated overview

A local MCP server that guides an assistant through an eight-phase, spec-driven development workflow with traceability and quality gates.

What it does
Vision Driven Design (VDD) is a spec-driven development MCP server. It structures work into eight phases, maintains bi-directional traceability between artifacts, and enforces seven quality gates. It runs locally over stdio and exposes its workflow to the assistant as MCP tools.
When to use it
Use it when you want an assistant to follow a disciplined, phase-based specification process for a software project, rather than ad-hoc coding. It suits teams that need traceability from requirements to implementation and explicit quality checkpoints.
Requirements
A local runtime with Node.js, since it is distributed as the npm package @simonmak-ascent/mcp and run with npx over stdio. It is desktop-only; no authentication, environment variables, or headers are declared.
Before you install
The registry description gives no detail on what the tools write or where project data is stored, so review the tool behavior before pointing it at a real repository. No credentials, payments, or third-party data flows are declared.

Installation
