+# MCP UI App
+
+A Next.js application for the MCP UI, configured for iframe embedding with CORS and CSP headers.
+
+## Getting Started
+
+### 1. Environment Setup
+
+Create a `.env.local` file in the app root with the following variables:
+
+```bash
+# Base URL for the application
+NEXT_PUBLIC_BASE_URL=http://localhost:3000
+
+# Allowed parent origins for iframe embedding (comma-separated)
+ALLOWED_IFRAME_ORIGINS=http://localhost:3000,http://localhost:3001,https://your-app.com
+```
+
+Configuration options:
+
+- `NEXT_PUBLIC_BASE_URL`: The base URL of your application
+- `ALLOWED_IFRAME_ORIGINS`: Comma-separated list of allowed parent origins for iframe embedding
+
+### 2. Install dependencies
+
+```bash
+pnpm install
+```
+
+### 3. Run the development server
+
+```bash
+pnpm dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+## Configuration
+
+### Base URL
+
+The base URL is configured via the `NEXT_PUBLIC_BASE_URL` environment variable and can be accessed in your code:
+
+```typescript
+import config from '@/config';
+
+console.log(config.baseUrl); // http://localhost:3000
+```
+
+### CORS and Iframe Embedding
+
+The app is configured with:
+
+- **CORS headers**: Allow cross-origin requests from specified origins
+- **CSP headers**: Content Security Policy appropriate for iframe embedding
+- **Frame ancestors**: Controls which domains can embed this app in an iframe
+
+To allow your app to be embedded in an iframe from specific domains, add them to the `ALLOWED_IFRAME_ORIGINS` environment variable.
+
+## Build
+
+This app is excluded from the default `pnpm build` command in the workspace. To build this app specifically, run:
+
+```bash
+cd apps/mcp-ui-app
+pnpm build
+```
+
+Or from the workspace root:
+
+```bash
+pnpm build:apps
+```
