-# 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
-```
