## Environment Variables
### Test Environment
```env
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_<your_publishable_key>
CLERK_SECRET_KEY=sk_test_<your_secret_key>
```
### Production Environment
```env
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_live_<your_publishable_key>
CLERK_SECRET_KEY=sk_live_<your_secret_key>
```
## Key Improvements
### 🎨 Better UX
- **Modal sign-in** - No page redirects, smoother experience
- **Professional UI** - Clerk's built-in user profile dropdown
- **Multiple auth methods** - Email, Google, GitHub, etc. (configurable in Clerk dashboard)
### 🔒 Enhanced Security
- **Managed by Clerk** - Automatic security updates
- **Session management** - Built-in token refresh and security
- **Protection** - CSRF, XSS, and other attack vectors handled by Clerk
### 🚀 Simpler Codebase
- **Less code** - No custom auth pages or OAuth configuration
- **No auth API route** - Clerk handles all authentication flows
- **Easier maintenance** - Authentication managed in Clerk dashboard
### 👤 User Isolation Maintained
- **Email-based isolation** - Each user's data separated by email
- **Automatic user creation** - Users added to MCP Memory DB on first sign-in
- **Backward compatible** - Existing user data works seamlessly
## Quick Start
```bash
# 1. Install dependencies
cd web && npm install
# 2. Configure environment (already has test keys)
cp .env.local.example .env.local
# Edit with your database and OpenAI credentials
# 3. Run development server
npm run dev
# 4. Visit http://localhost:3000 and test sign-in
```
## Testing Status
