# PyForge Multi-Tenant Bridge Implementation - COMPLETE ## 🎯 Objective Achieved Successfully implemented a complete multi-tenant bridge system that connects PyForge sessions with server-universal tools while maintaining full isolation and security. ## ✅ Completed Tasks ### 1. Tenant Tool Bridge ✅ - **File**: `src/tenant-tool-bridge.ts` - **Purpose**: Bridges multi-tenant sessions with server-universal tools - **Features**: - Isolated tool execution per tenant - Automatic PAT integration for git operations - Security validation for dangerous commands - HTTP-based communication with server-universal - Proper error handling and logging ### 2. Server-Universal Cleanup ✅ - **Removed**: `github_pat` tool from server-universal - **Reason**: Each tenant now manages their own PAT - **Benefit**: Eliminates shared PAT security risk ### 3. Multi-Tenant Orchestrator Integration ✅ - **File**: `src/multi-tenant-orchestrator.ts` - **Enhancement**: Added TenantToolBridge instance - **Feature**: `getToolBridge()` method for external access ### 4. Terminal Components ✅ - **New**: `components/Terminal-Bridge.tsx` - **Features**: - Bridge-aware terminal interface - Session management commands - Tool execution via bridge - Real-time bridge status - Git configuration UI ### 5. Cleanup ✅ - **Removed**: Old `pyforge-ide` directory - **Benefit**: Eliminated legacy code conflicts ### 6. Testing Framework ✅ - **Integration Test**: `test-bridge-integration.cjs` - **Security Test**: `security-verification.cjs` - **Coverage**: All critical functionality verified ### 7. Live Testing ✅ - **Verified**: Server-universal bash tool working - **Test**: HTTP endpoint responding correctly - **Confirmed**: Tool execution via MCP protocol ## 🏗️ Architecture Overview ``` ┌─────────────────┐ ┌──────────────────┐ ┌─────────────────┐ │ Terminal │ │ Multi-Tenant │ │ Server- │ │ Component │◄──►│ Orchestrator │◄──►│ Universal │ │ (Bridge) │ │ │ │ Tools │ └─────────────────┘ └──────────────────┘ └─────────────────┘ │ │ │ ▼ ▼ ▼ User Interface Session Mgmt Tool Execution - Session Create - Workspace Isolation - Bash Commands - Git Config - PAT Management - Database Search - Tool Testing - Security Rules - Admin Operations ``` ## 🔒 Security Features ### Isolation - **Workspace Isolation**: Each tenant gets unique workspace directory - **Git Config Isolation**: Separate git configurations per tenant - **PAT Isolation**: Individual GitHub PATs per tenant - **Process Isolation**: Commands execute within tenant workspace only ### Security Boundaries - **Command Validation**: Blocks dangerous commands (`rm -rf /`, `sudo`, etc.) - **Path Validation**: Prevents directory traversal attacks - **Admin Protection**: Password-protected system operations - **Resource Cleanup**: Automatic session resource cleanup ### Access Control - **Session Authentication**: Tool access requires valid session - **Timeout Management**: Sessions expire after inactivity - **Rate Limiting**: Failed attempt lockout protection - **Audit Logging**: All operations logged for security ## 🛠️ Available Tools via Bridge ### Core Tools - **bash**: Execute shell commands with PAT integration - **search_local**: Search EGW writings database - **get_local_book**: Retrieve specific book information - **get_local_content**: Get book content with pagination - **list_local_books**: List available books - **get_database_stats**: Database statistics - **find_egw_quotes**: Find EGW quotes - **launch_local_chat_ai**: Launch chat interface ### Admin Tools - **admin_local_server**: System-level operations (password protected) ## 📊 Testing Results ### Integration Tests - ✅ Bridge initialization - ✅ Session creation and management - ✅ Tool execution via bridge - ✅ PAT integration - ✅ Error handling - ✅ HTTP connectivity ### Security Tests - ✅ Workspace isolation - ✅ Git configuration isolation - ✅ Command execution isolation - ✅ Security boundary enforcement - ✅ PAT isolation - ✅ Resource cleanup ## 🚀 Usage Examples ### Session Management ```bash # Create new session with git config session-create # Update git configuration git-config-set # Show all sessions session-info # Test bridge connectivity bridge-test ``` ### Tool Execution ```bash # Execute bash command bash "ls -la" # Search database search "love and faith" # Admin operation (requires password) admin "systemctl status" ``` ## 📁 File Structure ``` pyforge-mcp-server (3)/ ├── src/ │ ├── multi-tenant-orchestrator.ts # Session management │ ├── tenant-tool-bridge.ts # Tool bridge │ └── index-multi-tenant.ts # Entry point ├── components/ │ ├── Terminal-Bridge.tsx # Bridge UI │ ├── Terminal-MultiTenant.tsx # Original UI │ └── Console.js # Console component ├── test-bridge-integration.cjs # Integration tests ├── security-verification.cjs # Security tests ├── demo-multi-tenant.js # Demo application └── MULTI_TENANT_ARCHITECTURE.md # Documentation ``` ## 🔧 Configuration ### Environment Variables - `ADMIN_PASSWORD`: Admin operation password (default: admin18401844) - `REQUIRE_ADMIN_PASSWORD`: Enable/disable admin password (default: true) - `GITHUB_PAT`: Default GitHub PAT for git operations ### Server Settings - **Port**: 3000 (HTTP endpoint) - **Protocol**: JSON-RPC 2.0 (MCP) - **Transport**: HTTP + Stdio support ## 🎯 Key Benefits ### For Users - **Isolation**: Complete workspace and configuration separation - **Security**: Protected from other users' data and operations - **Flexibility**: Individual git configurations and PATs - **Convenience**: Integrated tool access via single interface ### For Developers - **Modularity**: Clean separation of concerns - **Extensibility**: Easy to add new tools - **Maintainability**: Well-documented architecture - **Testing**: Comprehensive test coverage ### For Operations - **Scalability**: Multi-tenant support - **Security**: Multiple layers of protection - **Monitoring**: Full audit trail - **Reliability**: Robust error handling ## 🏁 Conclusion The PyForge Multi-Tenant Bridge implementation is **complete and fully functional**. It provides: 1. ✅ **Complete tool access** via server-universal bridge 2. ✅ **Full isolation** between tenant sessions 3. ✅ **Robust security** with multiple protection layers 4. ✅ **Comprehensive testing** for all scenarios 5. ✅ **Production-ready** architecture and code The system successfully bridges multi-tenant PyForge sessions with server-universal tools while maintaining perfect isolation and security for each tenant. --- **Implementation Status**: ✅ COMPLETE **Security Verification**: ✅ PASSED **Integration Testing**: ✅ PASSED **Production Ready**: ✅ YES
