MCP Memory Service - TypeScript

# Clerk Authentication Migration - Complete This document summarizes the migration from NextAuth.js to Clerk authentication in the MCP Memory web interface. ## Migration Summary Successfully replaced NextAuth.js with Clerk authentication v5.7.5. All authentication flows now use Clerk's managed authentication system. ## Changes Made ### 1. Dependencies Updated **File: `web/package.json`** - ❌ Removed: `next-auth@^4.24.0` - ✅ Added: `@clerk/nextjs@^5.7.5` ### 2. Root Layout Updated **File: `web/app/layout.tsx`** - Replaced `<AuthProvider>` (NextAuth SessionProvider) with `<ClerkProvider>` - Clerk provider now wraps the entire application ### 3. Middleware Updated **File: `web/middleware.ts`** - Replaced NextAuth middleware with Clerk's `clerkMiddleware` - Updated to use Clerk v5 API with `createRouteMatcher` - Public route: `/` (landing page) - All other routes protected by Clerk authentication ### 4. Authentication Helper Updated **File: `web/lib/auth.ts`** - Replaced `getServerSession` and `authOptions` with Clerk's `auth()` and `currentUser()` - Updated to use `@clerk/nextjs/server` imports (v5 API) - Removed `requireAuth()` function (no longer needed) - `getUserEmail()` now: 1. Gets userId from Clerk's `auth()` 2. Fetches user details with `currentUser()` 3. Extracts email from Clerk's user object 4. Ensures user exists in MCP Memory database ### 5. API Routes Updated **Files: All API routes in `web/app/api/`** - No direct changes needed - All routes use `getUserEmail()` from `lib/auth.ts` - Authentication automatically handled by updated `getUserEmail()` function ### 6. Navbar Component Updated **File: `web/components/layout/navbar.tsx`** - Replaced `useSession()` and `signOut()` with Clerk's `useUser()` and `<UserButton>` - Removed custom sign out button - Clerk's `<UserButton>` provides built-in profile/sign out UI ### 7. Landing Page Updated **File: `web/app/page.tsx`** - Replaced NextAuth redirect logic with Clerk's `auth()` check - Added Clerk's `<SignInButton>` component for authentication - Modal sign-in experience (no redirect to separate page) ### 8. Dashboard Page Updated **File: `web/app/dashboard/page.tsx`** - Replaced `requireAuth()` with direct `auth()` check - Updated environment variable from `NEXTAUTH_URL` to `NEXT_PUBLIC_APP_URL` ### 9. Removed Files **Deleted:** - `web/app/api/auth/[...nextauth]/route.ts` (NextAuth API route) - `web/app/auth/signin/page.tsx` (Custom sign-in page) - `web/app/auth/error/page.tsx` (Custom error page) ### 10. Auth Provider Simplified **File: `web/components/providers/auth-provider.tsx`** - Removed NextAuth's `SessionProvider` - Now a simple pass-through component (kept for backwards compatibility) - ClerkProvider is used directly in root layout instead ### 11. Environment Configuration **Created Files:** - `web/.env.local` - Test environment with Clerk test keys - `web/.env.production` - Production environment with Clerk live keys - `web/.env.local.example` - Example configuration file **Updated Files:** - `web/.gitignore` - Added `.env.production` to ignore list ## Environment Variables ### Test Environment (.env.local) ```env # Database TURSO_URL=libsql://your-database.turso.io TURSO_AUTH_TOKEN=your-auth-token # OpenAI OPENAI_API_KEY=your-openai-api-key # Clerk Test NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_<your_publishable_key> CLERK_SECRET_KEY=sk_test_<your_secret_key> ``` ### Production Environment (.env.production) ```env # Database TURSO_URL=libsql://your-database.turso.io TURSO_AUTH_TOKEN=your-auth-token # OpenAI OPENAI_API_KEY=your-openai-api-key # Clerk Production NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_live_<your_publishable_key> CLERK_SECRET_KEY=sk_live_<your_secret_key> ``` ## Key Improvements ### 1. Simpler Authentication Flow - No need to configure OAuth providers manually - Clerk handles all authentication UI and flows - Built-in user management dashboard ### 2. Better User Experience - Modal sign-in (no page redirects) - Professional user profile UI with `<UserButton>` - Automatic session management ### 3. Enhanced Security - Clerk manages session tokens and security - Built-in protection against common attacks - Regular security updates from Clerk ### 4. User Isolation - Still maintains MCP Memory's user isolation by email - `getUserEmail()` ensures user exists in database - All API routes properly isolated per user ## Testing Checklist After deployment, verify: - [ ] Sign in with Clerk works (modal appears) - [ ] User is redirected to dashboard after sign in - [ ] Navbar shows user email and profile button - [ ] API routes return data for authenticated user only - [ ] Sign out works and redirects to landing page - [ ] Different users see different memories (user isolation) - [ ] Stats dashboard loads correctly - [ ] Memory creation/search works - [ ] Entity management works ## Known Issues ### Build Warnings (Pre-existing, not Clerk-related) The following TypeScript errors exist in the parent project and are unrelated to the Clerk migration: - Type errors in `src/core/memory-core.ts` (implicit any types) - Type errors in `src/database/operations.ts` (implicit any types) - Module resolution issues with `.js` extensions in imports These should be fixed in the parent project's TypeScript configuration. ## Migration Commands ```bash # 1. Install dependencies cd web && npm install # 2. Configure environment cp .env.local.example .env.local # Edit .env.local with your credentials # 3. Run development server npm run dev # 4. Test authentication # Visit http://localhost:3000 # Click "Sign In" and test Clerk authentication ``` ## Rollback Instructions If you need to rollback to NextAuth: 1. Restore `package.json` with `next-auth@^4.24.0` 2. Restore previous versions of files from git 3. Restore deleted auth pages and API route 4. Run `npm install` 5. Update `.env.local` with NextAuth variables ## Support - **Clerk Documentation**: https://clerk.com/docs - **Clerk Dashboard**: https://dashboard.clerk.com - **MCP Memory Issues**: Check project GitHub issues --- **Migration Date**: 2025-10-03 **Clerk Version**: 5.7.5 **Status**: ✅ Complete
