Common questions

Is Marmo UI safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 4 months ago, and the latest version (1.1.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

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)

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`](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](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.

Light	Dark

Free vs Pro

	Free	Pro — $9.99/mo, 14-day free trial
React components (`@marmoui/ui`, MIT)	✓	✓
Core MCP — live props, validation, default Marmo styling	✓	✓
Docs, Figma library	✓	✓
On-brand generation — your `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, 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

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:

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.

Development

Node 20+, pnpm 9.

git clone git@github.com:mahmoudilyan/marmoui.git

cd marmo-ui pnpm install pnpm dev # UI package + docs site (localhost:3002)

Command	Description
`pnpm dev:ui`	Develop the UI package only
`pnpm build`	Build all packages and apps
`pnpm lint`	Run ESLint across the monorepo
`pnpm type-check`	Run TypeScript type checking
`pnpm changeset`	Add a semver changeset
