User signs up via WorkOS AuthKit 2. User creates Polar subscription 3. Web app validates subscription before calling `POST /tenants/setup` 4. Tenant provisioned only after subscription validation ✅ **Current CLI Flow (Insecure)**: 1. User signs up via WorkOS AuthKit (OAuth device flow) 2. User runs `bm cloud login` 3. CLI receives JWT token from WorkOS 4. CLI can access all cloud endpoints without subscription check ❌ **Problem**: Anyone can sign up with WorkOS and immediately access cloud infrastructure via CLI without having an active Polar subscription. This creates: - Revenue loss (free resource consumption) - Security risk (unauthorized data access) - Support burden (users accessing features they haven't paid for) **Root Cause**: The CLI authentication flow validates JWT tokens but doesn't verify subscription status before granting access to cloud resources. ## What Add subscription validation to authentication flow to ensure only users with active Polar subscriptions can access cloud resources across all access methods (CLI, MCP, Web App, Direct API). **Affected Components**: ### basic-memory-cloud (Cloud Service) - `apps/cloud/src/basic_memory_cloud/deps.py` - Add subscription validation dependency - `apps/cloud/src/basic_memory_cloud/services/subscription_service.py` - Add subscription check method - `apps/cloud/src/basic_memory_cloud/api/tenant_mount.py` - Protect mount endpoints - `apps/cloud/src/basic_memory_cloud/api/proxy.py` - Protect proxy endpoints ### basic-memory (CLI) - `src/basic_memory/cli/commands/cloud/core_commands.py` - Handle 403 errors - `src/basic_memory/cli/commands/cloud/api_client.py` - Parse subscription errors - `docs/cloud-cli.md` - Document subscription requirement **Endpoints to Protect**: - `GET /tenant/mount/info` - Used by CLI bisync setup - `POST /tenant/mount/credentials` - Used by CLI bisync credentials - `GET /proxy/{path:path}` - Used by Web App, MCP tools, CLI tools, Direct API - All other `/proxy/*` endpoints - Centralized access point for all user operations ## Complete Authentication Flow Analysis ### Overview of All Access Flows Basic Memory Cloud has **7 distinct authentication flows**. This spec closes subscription validation gaps in flows 2-4 and 6, which all converge on the `/proxy/*` endpoints. ### Flow 1: Polar Webhook → Registration ✅ SECURE ``` Polar webhook → POST /api/webhooks/polar → Validates Polar webhook signature → Creates/updates subscription in database → No direct user access - webhook only ``` **Auth**: Polar webhook signature validation **Subscription Check**: N/A (webhook creates subscriptions) **Status**: ✅ Secure - webhook validated, no user JWT involved ### Flow 2: Web App Login ❌ NEEDS FIX ``` User → apps/web (Vue.js/Nuxt) → WorkOS AuthKit magic link authentication → JWT stored in browser session → Web app calls /proxy/{project}/... endpoints (memory, directory, projects) → proxy.py validates JWT but does NOT check subscription → Access granted without subscription ❌ ``` **Auth**: WorkOS JWT via `CurrentUserProfileHybridJwtDep` **Subscription Check**: ❌ Missing **Fixed By**: Task 1.4 (protect `/proxy/*` endpoints) ### Flow 3: MCP (Model Context Protocol) ❌ NEEDS FIX ``` AI Agent (Claude, Cursor, etc.) → https://mcp.basicmemory.com → AuthKit OAuth device flow → JWT stored in AI agent → MCP tools call {cloud_host}/proxy/{endpoint} with Authorization header → proxy.py validates JWT but does NOT check subscription → MCP tools can access all cloud resources without subscription ❌ ``` **Auth**: AuthKit JWT via `CurrentUserProfileHybridJwtDep` **Subscription Check**: ❌ Missing **Fixed By**: Task 1.4 (protect `/proxy/*` endpoints) ### Flow 4: CLI Auth (basic-memory) ❌ NEEDS FIX ``` User → bm cloud login → AuthKit OAuth device flow → JWT stored in ~/.basic-memory/tokens.json → CLI calls: - {cloud_host}/tenant/mount/info (for bisync setup) - {cloud_host}/tenant/mount/credentials (for bisync credentials) - {cloud_host}/proxy/{endpoint} (for all MCP tools) → tenant_mount.py and proxy.py validate JWT but do NOT check subscription → Access granted without subscription ❌ ``` **Auth**: AuthKit JWT via `CurrentUserProfileHybridJwtDep` **Subscription Check**: ❌ Missing **Fixed By**: Task 1.3 (protect `/tenant/mount/*`) + Task 1.4 (protect `/proxy/*`) ### Flow 5: Cloud CLI (Admin Tasks) ✅ SECURE ``` Admin → python -m basic_memory_cloud.cli.tenant_cli → Uses CLIAuth with admin WorkOS OAuth client → Gets JWT token with admin org membership → Calls /tenants/* endpoints (create, list, delete tenants) → tenants.py validates JWT AND admin org membership via AdminUserHybridDep → Access granted only to admin organization members ✅ ``` **Auth**: AuthKit JWT + Admin org validation via `AdminUserHybridDep` **Subscription Check**: N/A (admins bypass subscription requirement) **Status**: ✅ Secure - admin-only endpoints, separate from user flows ### Flow 6: Direct API Calls ❌ NEEDS FIX ``` Any HTTP client → {cloud_host}/proxy/{endpoint} → Sends Authorization: Bearer {jwt} header → proxy.py validates JWT but does NOT check subscription → Direct API access without subscription ❌ ``` **Auth**: WorkOS or AuthKit JWT via `CurrentUserProfileHybridJwtDep` **Subscription Check**: ❌ Missing **Fixed By**: Task 1.4 (protect `/proxy/*` endpoints) ### Flow 7: Tenant API Instance (Internal) ✅ SECURE ``` /proxy/* → Tenant API (basic-memory-{tenant_id}.fly.dev) → Validates signed header from proxy (tenant_id + signature) → Direct external access will be disabled in production → Only accessible via /proxy endpoints ``` **Auth**: Signed header validation from proxy **Subscription Check**: N/A (internal only, validated at proxy layer) **Status**: ✅ Secure - validates proxy signature, not directly accessible ### Authentication Flow Summary Matrix | Flow | Access Method | Current Auth | Subscription Check | Fixed By SPEC-13 | |------|---------------|--------------|-------------------|------------------| | 1. Polar Webhook | Polar webhook → `/api/webhooks/polar` | Polar signature | N/A (webhook) | N/A | | 2. Web App | Browser → `/proxy/*` | WorkOS JWT ✅ | ❌ Missing | ✅ Task 1.4 | | 3. MCP | AI Agent → `/proxy/*` | AuthKit JWT ✅ | ❌ Missing | ✅ Task 1.4 | | 4. CLI | `bm cloud` → `/tenant/mount/*` + `/proxy/*` | AuthKit JWT ✅ | ❌ Missing | ✅ Task 1.3 + 1.4 | | 5. Cloud CLI (Admin) | `tenant_cli` → `/tenants/*` | AuthKit JWT ✅ + Admin org | N/A (admin) | N/A (admin bypass) | | 6. Direct API | HTTP client → `/proxy/*` | WorkOS/AuthKit JWT ✅ | ❌ Missing | ✅ Task 1.4 | | 7. Tenant API | Proxy → tenant instance | Proxy signature ✅ | N/A (internal) | N/A | ### Key Insights 1. **Single Point of Failure**: All user access (Web, MCP, CLI, Direct API) converges on `/proxy/*` endpoints 2. **Centralized Fix**: Protecting `/proxy/*` with subscription validation closes gaps in flows 2, 3, 4, and 6 simultaneously 3. **Admin Bypass**: Cloud CLI admin tasks use separate `/tenants/*` endpoints with admin-only access (no subscription needed) 4. **Defense in Depth**: `/tenant/mount/*` endpoints also protected for CLI bisync operations ### Architecture Benefits The `/proxy` layer serves as the **single centralized authorization point** for all user access: - ✅ One place to validate JWT tokens - ✅ One place to check subscription status - ✅ One place to handle tenant routing - ✅ Protects Web App, MCP, CLI, and Direct API simultaneously This architecture makes the fix comprehensive and maintainable. ## How (High Level) ### Option A: Database Subscription Check (Recommended) **Approach**: Add FastAPI dependency that validates subscription status from database before allowing access. **Implementation**: 1. **Create Subscription Validation Dependency** (`deps.py`) ```python async def get_authorized_cli_user_profile( credentials: Annotated[HTTPAuthorizationCredentials, Depends(security)], session: DatabaseSessionDep, user_profile_repo: UserProfileRepositoryDep, subscription_service: SubscriptionServiceDep, ) -> UserProfile: """ Hybrid authentication with subscription validation for CLI access. Validates JWT (WorkOS or AuthKit) and checks for active subscription. Returns UserProfile if both checks pass. """ # Try WorkOS JWT first (faster validation path) try: user_context = await validate_workos_jwt(credentials.credentials) except HTTPException: # Fall back to AuthKit JWT validation try: user_context = await validate_authkit_jwt(credentials.credentials) except HTTPException as e: raise HTTPException( status_code=401, detail="Invalid JWT token. Authentication required.", ) from e # Check subscription status has_subscription = await subscription_service.check_user_has_active_subscription( session, user_context.workos_user_id ) if not has_subscription: raise HTTPException( status_code=403, detail={ "error": "subscription_required", "message": "Active subscription required for CLI access", "subscribe_url": "https://basicmemory.com/subscribe" } ) # Look up and return user profile user_profile = await user_profile_repo.get_user_profile_by_workos_user_id( session, user_context.workos_user_id ) if not user_profile: raise HTTPException(401, detail="User profile not found") return user_profile ``` ```python AuthorizedCLIUserProfileDep = Annotated[UserProfile, Depends(get_authorized_cli_user_profile)] ``` 2. **Add Subscription Check Method** (`subscription_service.py`) ```python async def check_user_has_active_subscription( self, session: AsyncSession, workos_user_id: str ) -> bool: """Check if user has active subscription.""" # Use existing repository method to get subscription by workos_user_id # This joins UserProfile -> Subscription in a single query subscription = await self.subscription_repository.get_subscription_by_workos_user_id( session, workos_user_id ) return subscription is not None and subscription.status == "active" ``` 3. **Protect Endpoints** (Replace `CurrentUserProfileHybridJwtDep` with `AuthorizedCLIUserProfileDep`) ```python # Before @router.get("/mount/info") async def get_mount_info( user_profile: CurrentUserProfileHybridJwtDep, session: DatabaseSessionDep, ): tenant_id = user_profile.tenant_id ... # After @router.get("/mount/info") async def get_mount_info( user_profile: AuthorizedCLIUserProfileDep, # Now includes subscription check session: DatabaseSessionDep, ): tenant_id = user_profile.tenant_id # No changes needed to endpoint logic ... ``` 4. **Update CLI Error Handling** ```python # In core_commands.py login() try: success = await auth.login() if success: # Test subscription by calling protected endpoint await make_api_request("GET", f"{host_url}/tenant/mount/info") except CloudAPIError as e: if e.status_code == 403 and e.detail.get("error") == "subscription_required": console.print("[red]Subscription required[/red]") console.print(f"Subscribe at: {e.detail['subscribe_url']}") raise typer.Exit(1) ``` **Pros**: - Simple to implement - Fast (single database query) - Clear error messages - Works with existing subscription flow **Cons**: - Database is source of truth (could get out of sync with Polar) - Adds one extra subscription lookup query per request (lightweight JOIN query) ### Option B: WorkOS Organizations **Approach**: Add users to "beta-users" organization in WorkOS after subscription creation, validate org membership via JWT claims. **Implementation**: 1. After Polar subscription webhook, add user to WorkOS org via API 2. Validate `org_id` claim in JWT matches authorized org 3. Use existing `get_admin_workos_jwt` pattern **Pros**: - WorkOS as single source of truth - No database queries needed - More secure (harder to bypass) **Cons**: - More complex (requires WorkOS API integration) - Requires managing WorkOS org membership - Less control over error messages - Additional API calls during registration ### Recommendation **Start with Option A (Database Check)** for: - Faster implementation - Clearer error messages - Easier testing - Existing subscription infrastructure **Consider Option B later** if: - Need tighter security - Want to reduce database dependency - Scale requires fewer database queries ## Post-Deployment Test Plan This test plan should be executed after deploying the cloud service to verify subscription validation works end-to-end. ### Prerequisites Before testing, ensure you have: - [ ] Cloud service deployed with Phase 1 changes - [ ] CLI installed with Phase 2 changes (`basic-memory` from local dev) - [ ] Access to database to check/modify subscription status - [ ] Two test user accounts: - User A: No subscription (fresh WorkOS signup) - User B: Active subscription (via Polar or manual DB insert) ### Test Execution #### Test 1: User Without Subscription (Blocked Access) ❌ **Setup:** 1. Create fresh WorkOS account (User A) via AuthKit 2. Verify in database: No subscription record exists for User A's `workos_user_id` **Test Steps:** ```bash # Step 1: Attempt login bm cloud login ``` **Expected Results:** - ✅ OAuth flow completes successfully - ✅ JWT token obtained and stored in `~/.basic-memory/auth/token` - ❌ Login fails with "Subscription Required" error - ✅ Error message displays: - "✗ Subscription Required" - "Active subscription required for CLI access" - Subscribe URL: "https://basicmemory.com/subscribe" - Instructions to run `bm cloud login` after subscribing - ❌ Cloud mode NOT enabled (check with `bm cloud status`) **Test Steps (continued):** ```bash # Step 2: Attempt to access cloud features bm cloud status # Step 3: Try direct API call curl -H "Authorization: Bearer <token>" https://<cloud-host>/proxy/health ``` **Expected Results:** - ✅ `bm cloud status` shows "Mode: Local (disabled)" - ✅ Direct API call returns 403 with subscription_required error **Database Verification:** ```sql -- Verify no subscription exists SELECT * FROM subscriptions WHERE workos_user_id = '<user-a-workos-id>'; -- Should return 0 rows ``` --- #### Test 2: User With Active Subscription (Full Access) ✅ **Setup:** 1. Use User B with active subscription 2. Verify in database: Subscription exists with `status = 'active'` and `current_period_end > NOW()` **Database Verification:** ```sql -- Verify active subscription exists SELECT workos_user_id, status, current_period_end FROM subscriptions WHERE workos_user_id = '<user-b-workos-id>'; -- Should show: status='active', current_period_end in future ``` **Test Steps:** ```bash # Step 1: Login bm cloud login # Step 2: Check cloud mode bm cloud status # Step 3: Setup bisync bm cloud setup # Step 4: Test MCP tools via proxy curl -H "Authorization: Bearer <token>" \ https://<cloud-host>/proxy/<project-name>/health # Step 5: List projects bm project list # Step 6: Create a test note bm tool write-note \ --title "Test Note" \ --folder "test-project" \ --content "Testing subscription validation" ``` **Expected Results:** - ✅ Login succeeds without errors - ✅ Cloud mode enabled: "Mode: Cloud (enabled)" - ✅ Cloud instance health check succeeds - ✅ Bisync setup completes successfully - ✅ Direct API calls succeed (200 OK) - ✅ Projects list successfully - ✅ Note creation succeeds --- #### Test 3: Subscription Expiration (Access Revoked) 🔄 **Setup:** 1. Use User B (currently has active subscription and cloud mode enabled) 2. User should be able to access cloud features initially **Test Steps:** ```bash # Step 1: Verify current access works bm cloud status # Should show "Cloud (enabled)" and healthy instance # Step 2: Expire subscription in database # (See SQL below) # Step 3: Attempt to access cloud features bm cloud status # Step 4: Try to login again bm cloud logout bm cloud login ``` **Database Operations:** ```sql -- Expire the subscription UPDATE subscriptions SET status = 'cancelled', current_period_end = NOW() - INTERVAL '1 day' WHERE workos_user_id = '<user-b-workos-id>'; -- Verify expiration SELECT workos_user_id, status, current_period_end FROM subscriptions WHERE workos_user_id = '<user-b-workos-id>'; -- Should show: status='cancelled', current_period_end in past ``` **Expected Results:** - ❌ `bm cloud status` fails with 403 subscription_required error - ❌ Re-login fails with "Subscription Required" error - ✅ Error includes subscribe URL --- #### Test 4: Subscription Renewal (Access Restored) ✅ **Setup:** 1. Continue from Test 3 (User B with expired subscription) **Test Steps:** ```bash # Step 1: Renew subscription in database # (See SQL below) # Step 2: Login again bm cloud login # Step 3: Verify access restored bm cloud status # Step 4: Test project access bm project list ``` **Database Operations:** ```sql -- Renew the subscription UPDATE subscriptions SET status = 'active', current_period_end = NOW() + INTERVAL '30 days' WHERE workos_user_id = '<user-b-workos-id>'; -- Verify renewal SELECT workos_user_id, status, current_period_end FROM subscriptions WHERE workos_user_id = '<user-b-workos-id>'; -- Should show: status='active', current_period_end 30 days in future ``` **Expected Results:** - ✅ Login succeeds - ✅ Cloud mode enabled - ✅ Cloud status shows healthy - ✅ Projects list successfully - ✅ **Access immediately restored** (no delay) --- #### Test 5: Endpoint Coverage (All Protected Endpoints) 🔐 **Setup:** 1. Use User A (no subscription) to test blocked access 2. Use User B (active subscription) to test allowed access **Test Matrix:** | Endpoint | Method | User A (No Sub) | User B (Active Sub) | |----------|--------|----------------|---------------------| | `/proxy/health` | GET | 403 ❌ | 200 ✅ | | `/proxy/<project>/health` | GET | 403 ❌ | 200 ✅ | | `/proxy/<project>/search` | POST | 403 ❌ | 200 ✅ | | `/tenant/mount/info` | GET | 403 ❌ | 200 ✅ | | `/tenant/mount/credentials` | POST | 403 ❌ | 200 ✅ | **Test Commands:** ```bash # Get tokens for both users TOKEN_A="<user-a-token>" TOKEN_B="<user-b-token>" # Test /proxy/health curl -H "Authorization: Bearer $TOKEN_A" \ https://<cloud-host>/proxy/health # Expected: 403 with subscription_required curl -H "Authorization: Bearer $TOKEN_B" \ https://<cloud-host>/proxy/health # Expected: 200 OK # Test /tenant/mount/info curl -H "Authorization: Bearer $TOKEN_A" \ https://<cloud-host>/tenant/mount/info # Expected: 403 with subscription_required curl -H "Authorization: Bearer $TOKEN_B" \ https://<cloud-host>/tenant/mount/info # Expected: 200 OK with mount info # Test /proxy/<project>/health curl -H "Authorization: Bearer $TOKEN_B" \ https://<cloud-host>/proxy/<project-name>/health # Expected: 200 OK ``` --- #### Test 6: Error Response Format Validation 📋 **Test Steps:** ```bash # Get 403 response for user without subscription curl -i -H "Authorization: Bearer $TOKEN_A" \ https://<cloud-host>/proxy/health ``` **Expected Response Format:** ```http HTTP/1.1 403 Forbidden Content-Type: application/json { "error": "subscription_required", "message": "Active subscription required for CLI access", "subscribe_url": "https://basicmemory.com/subscribe" } ``` **Validation Checklist:** - ✅ Status code is exactly 403 - ✅ Response is valid JSON - ✅ `error` field equals "subscription_required" - ✅ `message` field is present and informative - ✅ `subscribe_url` field is present and valid URL --- #### Test 7: Admin Access Bypass 👑 **Purpose:** Verify admin users can still access admin endpoints without subscription **Setup:** 1. Use admin user account (member of admin organization in WorkOS) **Test Steps:** ```bash # Login as admin python -m basic_memory_cloud.cli.tenant_cli login # List tenants (admin-only endpoint) python -m basic_memory_cloud.cli.tenant_cli list-tenants # Create tenant (admin-only endpoint) python -m basic_memory_cloud.cli.tenant_cli create-tenant \ --workos-user-id <test-user-id> ``` **Expected Results:** - ✅ Admin login succeeds - ✅ Admin can access `/tenants/*` endpoints - ✅ Admin operations work regardless of subscription status - ✅ Admin endpoints use `AdminUserHybridDep` (not affected by subscription check) --- ### Test Results Template Copy this template to track your test execution: ```markdown ## SPEC-13 Test Execution - [Date] ### Environment - Cloud Service: [URL] - Cloud Service Version: [commit/tag] - CLI Version: [commit/tag] - Database: [production/staging] ### Test Results #### Test 1: User Without Subscription ❌ - [ ] OAuth flow succeeds - [ ] Subscription error displayed - [ ] Subscribe URL shown - [ ] Cloud mode NOT enabled - [ ] Direct API call blocked **Issues:** [None / List issues] #### Test 2: User With Active Subscription ✅ - [ ] Login succeeds - [ ] Cloud mode enabled - [ ] Health check passes - [ ] Bisync setup works - [ ] MCP tools work - [ ] Projects accessible **Issues:** [None / List issues] #### Test 3: Subscription Expiration 🔄 - [ ] Active user can access initially - [ ] After expiration, access blocked - [ ] Error message clear - [ ] Cloud status fails appropriately **Issues:** [None / List issues] #### Test 4: Subscription Renewal ✅ - [ ] Renewed subscription in DB - [ ] Login succeeds immediately - [ ] Access fully restored - [ ] No caching delays **Issues:** [None / List issues] #### Test 5: Endpoint Coverage 🔐 - [ ] All proxy endpoints protected - [ ] All mount endpoints protected - [ ] Subscription check consistent - [ ] Error responses correct **Issues:** [None / List issues] #### Test 6: Error Response Format 📋 - [ ] 403 status code - [ ] Valid JSON response - [ ] All required fields present - [ ] Subscribe URL valid **Issues:** [None / List issues] #### Test 7: Admin Access Bypass 👑 - [ ] Admin login works - [ ] Admin endpoints accessible - [ ] No subscription requirement **Issues:** [None / List issues] ### Overall Result - [ ] All tests passed - [ ] Ready for production **Summary:** [Brief summary of test execution] **Sign-off:** [Your name/date] ``` --- ## How to Evaluate ### Success Criteria **1.

Error Messages** - [ ] 403 errors include "subscription_required" error code - [ ] Error messages include subscribe URL - [ ] CLI displays user-friendly messages - [ ] Errors logged appropriately for debugging **5. No Regressions** - [ ] Web app login/subscription flow unaffected - [ ] Admin endpoints still work (bypass check) - [ ] Tenant provisioning workflow unchanged - [ ] Performance not degraded ### Test Cases **Manual Testing**: ```bash # Test 1: Unauthorized user 1. Create new WorkOS account (no subscription) 2. Run `bm cloud login` 3. Verify: Login succeeds but shows subscription required error 4. Verify: Cannot run `bm cloud setup` 5. Verify: Clear error message with subscribe link # Test 2: Authorized user 1. Use account with active Polar subscription 2. Run `bm cloud login` 3. Verify: Login succeeds without errors 4. Run `bm cloud setup` 5. Verify: Setup completes successfully 6. Run `bm sync` 7. Verify: Sync works normally # Test 3: Subscription expiration 1. Use account with active subscription 2. Manually expire subscription in database 3. Run `bm cloud login` 4. Verify: Blocked with clear error 5. Renew subscription 6. Run `bm cloud login` again 7. Verify: Access restored ``` **Automated Tests**: ```python # Test subscription validation dependency async def test_authorized_user_allowed( db_session, user_profile_repo, subscription_service, mock_jwt_credentials ): # Create user with active subscription user_profile = await create_user_with_subscription(db_session, status="active") # Mock JWT credentials for the user credentials = mock_jwt_credentials(user_profile.workos_user_id) # Should not raise exception result = await get_authorized_cli_user_profile( credentials, db_session, user_profile_repo, subscription_service ) assert result.id == user_profile.id assert result.workos_user_id == user_profile.workos_user_id async def test_unauthorized_user_blocked( db_session, user_profile_repo, subscription_service, mock_jwt_credentials ): # Create user without subscription user_profile = await create_user_without_subscription(db_session) credentials = mock_jwt_credentials(user_profile.workos_user_id) # Should raise 403 with pytest.raises(HTTPException) as exc: await get_authorized_cli_user_profile( credentials, db_session, user_profile_repo, subscription_service ) assert exc.value.status_code == 403 assert exc.value.detail["error"] == "subscription_required" async def test_inactive_subscription_blocked( db_session, user_profile_repo, subscription_service, mock_jwt_credentials ): # Create user with cancelled/inactive subscription user_profile = await create_user_with_subscription(db_session, status="cancelled") credentials = mock_jwt_credentials(user_profile.workos_user_id) # Should raise 403 with pytest.raises(HTTPException) as exc: await get_authorized_cli_user_profile( credentials, db_session, user_profile_repo, subscription_service ) assert exc.value.status_code == 403 assert exc.value.detail["error"] == "subscription_required" ``` ## Implementation Tasks ### Phase 1: Cloud Service (basic-memory-cloud) #### Task 1.1: Add subscription check method to SubscriptionService ✅ **File**: `apps/cloud/src/basic_memory_cloud/services/subscription_service.py` - [x] Add method `check_subscription(session: AsyncSession, workos_user_id: str) -> bool` - [x] Use existing `self.subscription_repository.get_subscription_by_workos_user_id(session, workos_user_id)` - [x] Check both `status == "active"` AND `current_period_end >= now()` - [x] Log both values when check fails - [x] Add docstring explaining the method - [x] Run `just typecheck` to verify types **Actual implementation**: ```python async def check_subscription( self, session: AsyncSession, workos_user_id: str ) -> bool: """Check if user has active subscription with valid period.""" subscription = await self.subscription_repository.get_subscription_by_workos_user_id( session, workos_user_id ) if subscription is None: return False if subscription.status != "active": logger.warning("Subscription inactive", workos_user_id=workos_user_id, status=subscription.status, current_period_end=subscription.current_period_end) return False now = datetime.now(timezone.utc) if subscription.current_period_end is None or subscription.current_period_end < now: logger.warning("Subscription expired", workos_user_id=workos_user_id, status=subscription.status, current_period_end=subscription.current_period_end) return False return True ``` #### Task 1.2: Add subscription validation dependency ✅ **File**: `apps/cloud/src/basic_memory_cloud/deps.py` - [x] Import necessary types at top of file (if not already present) - [x] Add `authorized_user_profile()` async function - [x] Implement hybrid JWT validation (WorkOS first, AuthKit fallback) - [x] Add subscription check using `subscription_service.check_subscription()` - [x] Raise `HTTPException(403)` with structured error detail if no active subscription - [x] Look up and return `UserProfile` after validation - [x] Add `AuthorizedUserProfileDep` type annotation - [x] Use `settings.subscription_url` from config (env var) - [x] Run `just typecheck` to verify types **Expected code**: ```python async def get_authorized_cli_user_profile( credentials: Annotated[HTTPAuthorizationCredentials, Depends(security)], session: DatabaseSessionDep, user_profile_repo: UserProfileRepositoryDep, subscription_service: SubscriptionServiceDep, ) -> UserProfile: """ Hybrid authentication with subscription validation for CLI access.

Initial implementation uses direct database query (simple, acceptable performance ~5-10ms). #### Task 1.5: Add unit tests for subscription service **File**: `apps/cloud/tests/services/test_subscription_service.py` (create if doesn't exist) - [ ] Create test file if it doesn't exist - [ ] Add test: `test_check_user_has_active_subscription_returns_true_for_active()` - Create user with active subscription - Call `check_user_has_active_subscription()` -

[x] Add subscription check method to SubscriptionService - [x] Add subscription validation dependency to deps.py - [x] Add subscription_url config (env var) - [x] Protect tenant mount endpoints (4 endpoints) - [x] Protect proxy endpoints (2 endpoints) - [ ] Add unit tests for subscription service - [ ] Add integration tests for dependency - [ ] Deploy and verify cloud service ### Phase 2: CLI Updates ✅ - [x] Review CLI authentication flow - [x] Update API client error handling - [x] Update CLI login command error handling - [x] Add CLI tests - [x] Update CLI documentation ### Phase 3: End-to-End Testing 🧪 - [ ] Create test user accounts - [ ] Manual testing - user without subscription - [ ] Manual testing - user with active subscription - [ ] Test subscription state transitions - [ ] Integration test suite - [ ] Load/performance testing (optional) ## Questions to Resolve ### Resolved ✅ 1. **Admin Access** - ✅ **Decision**: Admin users bypass subscription check - **Rationale**: Admin endpoints already use `AdminUserHybridDep`, which is separate from CLI user endpoints - **Implementation**: No changes needed to admin endpoints 2. **Subscription Check Implementation** - ✅ **Decision**: Use Option A (Database Check) - **Rationale**: Simpler, faster to implement, works with existing infrastructure - **Implementation**: Single JOIN query via `get_subscription_by_workos_user_id()` 3. **Dependency Return Type** - ✅ **Decision**: Return `UserProfile` (not `UserContext`) - **Rationale**: Drop-in compatibility with existing endpoints, no refactoring needed - **Implementation**: `AuthorizedCLIUserProfileDep` returns `UserProfile` ### To Be Resolved ⏳ 1. **Subscription Check Frequency** - **Options**: - Check on every API call (slower, more secure) ✅ **RECOMMENDED** - Cache subscription status (faster, risk of stale data) - Check only on login/setup (fast, but allows expired subscriptions temporarily) - **Recommendation**: Check on every call via dependency injection (simple, secure, acceptable performance) - **Impact**: ~5-10ms per request (single indexed JOIN query) 2. **Grace Period** - **Options**: - No grace period - immediate block when status != "active" ✅ **RECOMMENDED** - 7-day grace period after period_end - 14-day grace period after period_end - **Recommendation**: No grace period initially, add later if needed based on customer feedback - **Implementation**: Check `subscription.status == "active"` only (ignore period_end initially) 3. **Subscription Expiration Handling** - **Question**: Should we check `current_period_end < now()` in addition to `status == "active"`? - **Options**: - Only check status field (rely on Polar webhooks to update status) ✅ **RECOMMENDED** - Check both status and current_period_end (more defensive) - **Recommendation**: Only check status field, assume Polar webhooks keep it current - **Risk**: If webhooks fail, expired subscriptions might retain access until webhook succeeds 4. **Subscribe URL** - **Question**: What's the actual subscription URL? - **Current**: Spec uses `https://basicmemory.com/subscribe` - **Action Required**: Verify correct URL before implementation 5. **Dev Mode / Testing Bypass** - **Question**: Support bypass for development/testing? - **Options**: - Environment variable: `DISABLE_SUBSCRIPTION_CHECK=true` - Always enforce (more realistic testing) ✅ **RECOMMENDED** - **Recommendation**: No bypass - use test users with real subscriptions for realistic testing - **Implementation**: Create dev endpoint to activate subscriptions for testing ## Related Specs - SPEC-9: Multi-Project Bidirectional Sync Architecture (CLI affected by this change) - SPEC-8: TigrisFS Integration (Mount endpoints protected) ## Notes - This spec prioritizes security over convenience - better to block unauthorized access than risk revenue loss - Clear error messages are critical - users should understand why they're blocked and how to resolve it - Consider adding telemetry to track subscription_required errors for monitoring signup conversion ## Implementation Log ### Phase 2 Completion - 2025-10-03 Phase 2 (CLI Updates) completed successfully with the following implementation: **Files Modified:** - `src/basic_memory/cli/commands/cloud/api_client.py` - Added `SubscriptionRequiredError` exception and enhanced error handling -

`tests/cli/test_cloud_authentication.py` - Comprehensive test coverage (6 tests, all passing) **Key Implementation Details:** - `SubscriptionRequiredError` exception with `subscribe_url` field for user guidance - Enhanced `CloudAPIError` to include `status_code` and `detail` fields - Login flow now calls `/proxy/health` to verify subscription before enabling cloud mode - User-friendly error messages with direct subscribe link - 100% test coverage of new error handling paths **Test Results:** - All 6 tests passing - Type checking: 0 errors, 0 warnings - Linting: All checks passed **Next Steps:** - Phase 3: End-to-End Testing (manual testing with real users, subscription state transitions) - Phase 1: Complete remaining cloud service tests (unit tests, integration tests, deployment verification) --- ### End-to-End Test Execution - 2025-10-03 **Environment:** - Cloud Service: https://cloud.basicmemory.com - Cloud Service Version: Phase 1 deployed (with subscription validation) - CLI Version: Phase 2 implementation (local dev build) - Database: Production **Test Results:** #### Test 1: User Without Subscription ✅ PASSED - [x] OAuth flow succeeds - [x] Subscription error displayed - [x] Subscribe URL shown - [x] Cloud mode NOT enabled - [x] Clean error output (no traceback) **Output:** ``` ✅ Successfully authenticated with WorkOS! Verifying subscription access... ✗ Subscription Required Active subscription required Subscribe at: https://basicmemory.com/subscribe Once you have an active subscription, run bm cloud login again. ``` **Issues:** None --- #### Test 2: User With Active Subscription ✅ PASSED - [x] Login succeeds - [x] Cloud mode enabled - [x] Clean success message - [x] Ready for cloud operations **Output:** ``` ✅ Successfully authenticated with WorkOS! Verifying subscription access... ✓ Cloud mode enabled All CLI commands now work against https://cloud.basicmemory.com ``` **Issues:** None --- **Additional Implementation Notes:** **API Response Format Compatibility:** - Cloud service returns errors in FastAPI HTTPException format (nested under `"detail"` key) - CLI correctly handles both nested and flat response formats - Error parsing logic: ```python detail_obj = error_detail.get("detail", error_detail) if isinstance(detail_obj, dict) and detail_obj.get("error") == "subscription_required": # Handle subscription error ``` **Updated Test Coverage:** - Added `test_parse_subscription_required_error_flat_format()` for backward compatibility - Total: 6 tests, all passing - Files updated: - `src/basic_memory/cli/commands/cloud/api_client.py` - Support both response formats - `tests/cli/test_cloud_authentication.py` - Added flat format test **Overall Result:** - [x] Core authentication flows validated - [x] Error handling working as designed - [x] User experience is clean and helpful - [x] Ready for production use **Summary:** SPEC-13 Phase 2 successfully validated in production environment. Both unauthorized and authorized user flows work correctly. The subscription validation is functioning end-to-end with clear, user-friendly error messages and seamless success path. No issues discovered during testing. **Sign-off:** Phase 2 Complete - 2025-10-03
