### Description (declared)

# Web UI Component Specification — MCP Server

An MCP (Model Context Protocol) server that gives AI coding assistants direct access to the Web UI Component Specification — a comprehensive behavioral reference for web UI component libraries covering component specs, test scenarios, accessibility requirements, and a step-by-step build guide.

---

## What this does

Instead of pasting spec content into prompts manually, this server lets your
AI assistant query exactly what it needs, when it needs it:

- **Building a component?** → Fetch its full spec on demand
- **Writing tests?** → Get just the test scenarios
- **Starting a library?** → Get a curated component list for your project type
- **Reviewing an implementation?** → Validate it against the spec automatically

---

## Read the specification

Prefer the human-readable version? Download the full spec as a PDF:

**[Web UI Component Specification (v1.0) — PDF](https://github.com/gcsebas99/web-ui-component-spec-mcp/raw/main/exports/v1.0/Web_UI_Component_Specification_v1.0.pdf)**

All exported versions live under [`exports/`](exports/).
