Ignite UI Theming MCP

Ignite UI Theming - from Infragistics

The Ignite UI Theming repository collects a set of Sass mixins, functions, and variables used to create themes for a variety of UI frameworks built by Infragistics. The theming package makes it super easy to create palettes, elevations and typography styles for your projects.

Repository Structure

This repository is an npm workspaces monorepo with two packages:

Package Name Description packages/theming igniteui-theming Sass source, JSON build artifacts, published to npm packages/mcp igniteui-theming-mcp MCP server sources, built into packages/theming/dist/mcp/

The igniteui-theming package is the only published artifact — it includes both the Sass theming library and the MCP server binary.

Common commands from the repo root:

npm install # install all workspace dependencies
npm run build # build theming + MCP in dependency order
npm test # run all tests across both packages
npm run lint # lint all packages

Palettes

We provide four predefined palettes - material, bootstrap, fluent and indigo that have all the necessary colors along with diffent variants of those colors to make it even easier picking the right one for your case. Here's what they look like:

To access any of the colors in the palettes, you can use the color function:

background: color($light-material-palette, 'primary', 500);

You can take a further look on what color functions and mixins the package contains and how to use them in the Colors Wiki Page

Typography

Another valuable module of our theming package is the typography, helping you have consistency all over your project. There are again four typography presets for the four themes that we provide out of the box.

You can set any of the typefaces by using the typography mixin, which accepts 2 arguments(font-family and type-scale). By default the typography is using the material typeface and type-scale.

@include typography($font-family: $material-typeface, $type-scale: $material-type-scale);

Learn more about the typography module in the package by checking out the Typography Wiki Page

Elevations

The theming package is providing one preset of shadows that can be used to give your components a lift. They're super helpful using with buttons, cards, navigation bars, etc.

You can set elevations 0-24, by using the elevation function, which accepts the elevation level as an argument:

box-shadow: elevation(12);

Learn more about elevations and their abilities in the Elevations Wiki Page

Linting and Testing

To scan the project for linting errors, run

npm run lint

To run the suite of tests, run

npm run test

Testing and Debugging

Preview Palettes

Run from packages/theming. Pass the palette (material, bootstrap, fluent, indigo) and variant (light or dark).

npm run preview:palette -- --palette=material --variant=light

MCP Server (AI-Assisted Theming)

The Ignite UI Theming package includes a Model Context Protocol (MCP) server that enables AI assistants to generate production-ready theming code for your Ignite UI applications. This MCP server is part of the larger AI-assisted development toolchain for Ignite UI.

What is MCP?

The Model Context Protocol allows AI assistants (like Claude, GitHub Copilot, and others) to connect to external tools and data sources. The Ignite UI Theming MCP server acts as an expert theming assistant that can:

• 🎨 Generate color palettes with automatic shade variations

• 📝 Create typography systems following design standards

• 🌓 Build complete themes for light and dark modes

• 🎯 Customize components with design tokens

• ✅ Validate colors for accessibility compliance

Quick Start

1. Clone and Build

Clone the repository and build:

npm install
npm run build

2. Configure Your AI Client

The MCP server works with any MCP-compatible client. Here are setup instructions for popular clients:

VS Code (with MCP-compatible extensions) For local development - Create or edit .vscode/mcp.json:

{
 "servers": {
 "igniteui-theming": {
 "command": "node",
 "args": ["/absolute/path/to/igniteui-theming/packages/theming/dist/mcp/index.js"]
 }
 }
}

Using published package:

{
 "servers": {
 "igniteui-theming": {
 "command": "npx",
 "args": ["-y", "igniteui-theming", "igniteui-theming-mcp"]
 }
 }
}

What Can It Do?

🎨 Create Complete Themes

Simply describe your theme to your AI assistant:

"Create a Material Design dark theme for my Angular app with that takes inspiration from the Gruvbox color scheme."

The AI will generate production-ready Sass code with:

• Color palette with all shade variations

• Typography setup with proper type scales

• Elevation shadows

• Platform-specific imports and configuration

🌈 Generate Color Palettes

"Generate a light theme palette using teal as primary and purple as secondary"

Get perfectly calculated color shades following design system standards.

📝 Setup Typography

"Set up typography using Inter font with Material Design type scale for Web Components"

Get proper typography configuration with font families and responsive type scales.

🎯 Customize Components

"What design tokens are available for the button component?"

"Create a flat button theme with purple background and white text"

Discover and customize individual component styles using design tokens.

Example Interactions

Creating a new project theme You: "I'm starting a new Angular project with Ignite UI. Create a complete Material Design theme with primary blue, secondary coral, light theme, and Roboto font"

AI: Uses create_theme tool and generates complete Sass code ready to use

Adding dark mode You: "I need a dark mode version with the same primary blue but dark surface"

AI: Uses create_theme with variant: "dark" and generates dark theme code

Customizing components You: "What properties can I customize on the card component?"

AI: Uses get_component_design_tokens to show available tokens

You: "Make the card have a light gray background with subtle shadow"

AI: Uses create_component_theme to generate component theme code

Usage

In order to use the Ignite UI Theming in your application you should install the igniteui-theming package:

npm install igniteui-theming

Next, you will need to use it in the file that you want like this:

@use '.../node_modules/igniteui-theming/' as *;

You can also use just a fraction of the package:

@use '.../node_modules/igniteui-theming/sass/color' as *;

We provide presets for material, bootstrap, fluent and indigo themes for the color(light and dark palettes), typography and elevations fractions. You can import them into your scss file like this:

@use '.../node_modules/igniteui-theming/sass/typography/presets' as *;

You can read more about what the package contains on the Wiki page
