+# MCP Server Implementation
+
+This document describes the Model Context Protocol (MCP) server implementation for the Ignite UI CLI and Angular Schematics packages.
+
+## Overview
+
+The MCP server provides a programmatic interface for AI assistants to interact with Ignite UI CLI functionality. It follows the [Model Context Protocol](https://modelcontextprotocol.io/) specification.
+
+## Packages
+
+### @igniteui/cli MCP Server
+
+The CLI package includes an `mcp` command that exposes key CLI functionality through MCP tools.
+
+#### Usage
+
+To start the MCP server:
+
+```bash
+ig mcp
+```
+
+Or via npx:
+
+```bash
+npx igniteui-cli mcp
+```
+
+#### Configuration
+
+Add the following configuration to your MCP host:
+
+```json
+{
+  "mcpServers": {
+    "igniteui-cli": {
+      "command": "npx",
+      "args": ["-y", "igniteui-cli", "mcp"]
+    }
+  }
+}
+```
+
+#### Available Tools
+
+1. **ig_new** - Create a new Ignite UI project
+   - Parameters: name, framework, type, theme, skipGit, skipInstall, template
+
+2. **ig_add** - Add a component template to an existing project
+   - Parameters: template, name, module, skipRoute
+
+3. **ig_upgrade_packages** - Upgrade Ignite UI packages
+   - Parameters: skipInstall
+
+4. **ig_list_templates** - List available frameworks and templates
+   - No parameters
+
+5. **ig_interactive** - Start interactive step-by-step mode
+   - No parameters
+
+#### Options
+
+- `--read-only`: Only register read-only tools (default: false)
+
+### @igniteui/angular-schematics MCP Server
+
+The ng-schematics package includes an MCP server for Angular-specific functionality.
+
+#### Usage
+
+Via Angular CLI schematic:
+
+```bash
+ng generate @igniteui/angular-schematics:mcp
+```
+
+#### Available Tools
+
+1. **ng_new_igniteui** - Create a new Angular project with Ignite UI
+   - Parameters: name, template, theme, skipGit
+
+2. **ng_add_component** - Add an Ignite UI component
+   - Parameters: template, name, module, skipRoute
+
+3. **ng_list_components** - List available components
+   - No parameters
+
+4. **ng_upgrade_packages** - Upgrade to licensed packages
+   - No parameters
+
+## Development
+
+### Building
+
+```bash
+npm run build
+```
+
+### Testing
+
+```bash
+npm test
+```
+
+### Linting
+
+```bash
+npm run lint
+```
+
+## Implementation Details
+
+- Both packages use the `@modelcontextprotocol/sdk` library
+- The MCP server uses stdio transport for communication
+- When run in a TTY (interactive terminal), the command displays usage instructions
+- When run non-interactively (e.g., from an MCP host), it starts the MCP server
