## Documentation & README

# Marmo UI

**The AI agentic designer.** Point the agent you already use — Claude Code, Codex, Cursor, Gemini CLI — at Marmo and it builds production dashboards and apps in minutes: real components, real props, your own style. No AI slop.

**Platform, docs & pricing → [marmoui.com](https://www.marmoui.com)**

```bash
npx marmoui init     # connect your agent (free, no account)
npm i @marmoui/ui    # the component library (MIT)
```

Then just ask your agent: *"Build a billing dashboard with Marmo UI."*

## How it works

- **[`@marmoui/ui`](https://github.com/mahmoudilyan/marmoui/blob/HEAD/packages/ui)** — an open-source React 19 design system (MIT, public npm). Tables, charts, forms, app shells — everything a product UI needs, light + dark from one token set.
- **The Marmo MCP** — a hosted knowledge server your agent connects to. Instead of guessing from training data, the agent reads live component APIs, composition patterns, and generation rules, and validates its output (`review_generated_code`) before reporting done. Wrong imports and invented props get caught and fixed before you ever see them.
- **[Claude Code plugin](https://github.com/mahmoudilyan/marmoui/blob/HEAD/tools/claude-plugin)** — `/plugin marketplace add mahmoudilyan/marmoui` → `/plugin install marmo-ui@marmoui-plugins`. Bundles the MCP plus the `marmo-ui` skill and `/marmo-ui:*` commands (`init`, `design-md`, `build`) that enforce the find → generate → validate workflow.

## Light and dark from one token set

Every component ships both themes off the same semantic tokens (`bg`, `panel`, `ink`, `primary-*`) — no parallel dark stylesheet, no hardcoded hex.

## Free vs Pro

| | Free | [Pro — $9.99/mo, 14-day free trial](https://www.marmoui.com/pricing) |
| --- | --- | --- |
| React components (`@marmoui/ui`, MIT) | ✓ | ✓ |
| Core MCP — live props, validation, default Marmo styling | ✓ | ✓ |
| Docs, Figma library | ✓ | ✓ |
| **On-brand generation** — your [`DESIGN.md`](https://www.marmoui.com/docs/tools/design-md) (colors, type, tokens, component overrides) drives every screen any connected agent generates | | ✓ |
| Composition patterns library (app shells, dashboards, forms) | | ✓ |
| Pro blocks, generated straight into your repo | | ✓ |
| Personal MCP token + hosted, brand-themed design-system page | | ✓ |

**Pro mode in one sentence:** the free tier makes your agent *correct*; Pro makes it *yours* — run `/marmo-ui:init` (or write a `DESIGN.md` by hand), upload it at [marmoui.com/connect](https://www.marmoui.com/connect), and every agent on your account generates UI in your brand instead of the Marmo defaults. Generation always happens in **your** agent with **your** LLM tokens; the code lands in your repo and you own it fully.

## Monorepo structure

```
├── apps/
│   └── design-system-docs/    # marmoui.com — docs + marketing site
├── packages/
│   ├── ui/                    # @marmoui/ui — publishable component library
│   └── cli/                   # marmoui — npx marmoui init
└── tools/claude-plugin/       # Claude Code plugin + marketplace
```

The hosted MCP server and platform services live in a private repository; this repo talks to them only through the hosted MCP at `mcp.marmoui.com`.

## Using `@marmoui/ui` directly

Works as a regular component library too — no agent required:

```tsx
import '@marmoui/ui/style.css'; // once, in your app entry
import { Button, DataTable } from '@marmoui/ui';
```

React 19 + `react-dom` are peer dependencies. Component APIs and examples: [marmoui.com/docs](https://www.marmoui.com/docs/introduction/get-started).
