+## MCP Server
+
+The repository includes an MCP (Model Context Protocol) server that enables AI assistants and developer tools to generate CSS from igniteui-theming presets. This makes it easy to implement design system CSS as handed off from design tools like Figma and Sketch.
+
+### Features
+
+The MCP server provides tools for generating:
+- Color palette CSS variables (material, bootstrap, fluent, indigo themes with light/dark variants)
+- Typography definitions and utility classes
+- Elevation (box-shadow) definitions
+- Sizing and spacing utilities
+- Complete theme CSS bundles
+
+### Installation
+
+```bash
+cd mcp-server
+npm install
+```
+
+### Usage
+
+Run the MCP server:
+
+```bash
+cd mcp-server
+npm start
+```
+
+Configure in your MCP client (e.g., Claude Desktop, Cline):
+
+```json
+{
+  "mcpServers": {
+    "igniteui-theming": {
+      "command": "node",
+      "args": ["/path/to/igniteui-theming/mcp-server/index.js"]
+    }
+  }
+}
+```
+
+For more details, see [mcp-server/README.md](mcp-server/README.md).

+
+This document shows example outputs from the IgniteUI Theming MCP Server tools.
+
+## Example 1: Generate Material Light Color Palette
+
+**Tool:** `generate_color_palette`
+**Arguments:**
+```json
+{
+  "theme": "material",
+  "variant": "light"
+}
+```
+
+**Output:** CSS file with color palette variables for all color shades (primary, secondary, gray, surface, info, success, warn, error) from 50 to 900, plus A100-A700 shades.
+
+## Example 2: Generate Bootstrap Typography
+
+**Tool:** `generate_typography`
+**Arguments:**
+```json
+{
+  "theme": "bootstrap"
+}
+```
+
+**Output:** CSS file with typography variables and utility classes for all type scales (h1-h6, subtitle-1, subtitle-2, body-1, body-2, button, caption, overline).
+
+## Example 3: Generate Material Elevations
+
+**Tool:** `generate_elevations`
+**Arguments:**
+```json
+{
+  "theme": "material"
+}
+```
+
+**Output:** CSS file with elevation (box-shadow) variables and utility classes for levels 0-24.
+
+## Example 4: Generate Sizing and Spacing Utilities
+
+**Tool:** `generate_sizing_spacing`
+**Arguments:**
+```json
+{}
+```
+
+**Output:** CSS file with sizing and spacing variables and utility classes (small, medium, large sizes; compact, cosy, comfortable spacing).
+
+## Example 5: Generate Complete Fluent Dark Theme
+
+**Tool:** `generate_complete_theme`
+**Arguments:**
+```json
+{
+  "theme": "fluent",
+  "variant": "dark"
+}
+```
+
+**Output:** Complete CSS theme file combining all the above components for the Fluent dark theme.
+
+## Integration with Design Tools
+
+The MCP server enables seamless integration with design tools:
+
+1. **From Figma**: Export design tokens → Use MCP to generate matching CSS
+2. **From Sketch**: Extract color palette → Generate CSS variables
+3. **From Adobe XD**: Get typography specs → Create utility classes
+
+## Use Cases
+
+### Use Case 1: Multi-Brand Application
+
+Generate different theme variants for different brands:
+
+```javascript
+// Brand A - Material Light
+generate_complete_theme({ theme: "material", variant: "light" })
+
+// Brand B - Fluent Dark  
+generate_complete_theme({ theme: "fluent", variant: "dark" })
+```
+
+### Use Case 2: Light/Dark Mode Toggle
+
+Generate both variants of the same theme:
+
+```javascript
+// Light mode CSS
+generate_color_palette({ theme: "bootstrap", variant: "light" })
+
+// Dark mode CSS
+generate_color_palette({ theme: "bootstrap", variant: "dark" })
+```
+
+### Use Case 3: Component Library Styling
+
+Generate specific utilities for a component library:
+
+```javascript
+// Typography utilities
+generate_typography({ theme: "material" })
+
+// Elevation utilities
+generate_elevations({ theme: "material" })
+
+// Spacing utilities
+generate_sizing_spacing({})
+```
+
+## Tips
+
+1. **Consistency**: Use the same theme across all tools for consistency
+2. **Customization**: Generated CSS uses CSS variables, making it easy to customize
+3. **Performance**: Generate CSS once, reuse across multiple projects
+4. **Maintenance**: Update theme by regenerating CSS when design system changes

+# IgniteUI Theming MCP Server Implementation
+
+## Overview
+
+This implementation adds a complete MCP (Model Context Protocol) server to the igniteui-theming repository, enabling AI assistants and developer tools to generate production-ready CSS from the library's theming presets.
+
+## What Was Implemented
+
+### 1. MCP Server (`mcp-server/index.js`)
+A fully functional MCP server that exposes 5 tools:
+
+- **generate_color_palette** - Generates CSS color palette variables
+  - Supports: material, bootstrap, fluent, indigo themes
+  - Variants: light, dark
+  - Output: ~200+ CSS variables for all color shades (50-900, A100-A700)
+
+- **generate_typography** - Generates typography definitions
+  - Supports: material, bootstrap, fluent, indigo themes
+  - Output: CSS variables and utility classes for h1-h6, subtitles, body, buttons, captions, overlines
+
+- **generate_elevations** - Generates elevation (box-shadow) definitions
+  - Supports: material, indigo themes
+  - Output: 25 elevation levels (0-24) as CSS variables and classes
+
+- **generate_sizing_spacing** - Generates sizing and spacing utilities
+  - Output: CSS variables for sizes (small, medium, large) and spacing modes (compact, cosy, comfortable)
+
+- **generate_complete_theme** - Generates complete theme bundles
+  - Combines all the above into a single comprehensive CSS file
+
+### 2. CLI Tool (`mcp-server/cli.js`)
+A command-line interface for testing and direct usage:
+
+```bash
+node cli.js palette --theme=material --variant=light
+node cli.js typography --theme=bootstrap
+node cli.js elevations --theme=material --output=output.css
+node cli.js spacing
+```
+
+### 3. Test Suite (`mcp-server/test.js`)
+Automated tests that validate:
+- Color palette generation for multiple themes/variants
+- Typography generation
+- Elevations generation
+- Proper CSS output structure
+
+### 4. Documentation
+
+- **README.md** - Complete user guide with installation, usage, and examples
+- **EXAMPLES.md** - Use case examples and integration patterns
+- **demo.html** - Interactive HTML demo showcasing the generated CSS
+
+### 5. Configuration
+
+- **package.json** - MCP server dependencies and scripts
+- **.gitignore** - Excludes test outputs and examples
+- Updated main package.json to include MCP server in npm package
+
+## Technical Details
+
+### Architecture
+- Built on `@modelcontextprotocol/sdk` for MCP protocol compliance
+- Uses `sass-embedded` for high-performance Sass compilation
+- Uses `postcss` for CSS post-processing (comment stripping)
+- ES modules throughout for modern JavaScript
+
+### Code Quality
+- All linting passing (stylelint, prettier)
+- All tests passing (99 existing + 3 new MCP tests)
+- Build process unchanged and working
+- Minimal changes to existing codebase
+
+### Integration Points
+- Integrates with existing Sass color functions and palettes
+- Uses existing typography presets
+- Uses existing elevation definitions
+- Respects existing theme structure
