# Security Considerations [TOC] This document outlines the security architecture, practices, and considerations for the MCP Online Platform. Security is a critical aspect of the platform as it handles sensitive user credentials and provides access to potentially confidential data through MCP services. ## Security Architecture Overview The security architecture of the MCP Online Platform follows defense-in-depth principles, with multiple layers of security controls to protect user data and system resources. ``` ┌─────────────────────────────────────────────────────────────────┐ │ Perimeter Security │ │ - DDoS Protection │ │ - Web Application Firewall │ │ - HTTPS Enforcement │ └────────────────────────────────┬────────────────────────────────┘ │ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ Authentication Layer │ │ - JWT Validation │ │ - API Key Authentication │ │ - Credential Management │ └────────────────────────────────┬────────────────────────────────┘ │ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ Authorization Layer │ │ - Role-Based Access Control │ │ - Permission Scopes │ │ - Resource Ownership Validation │ └────────────────────────────────┬────────────────────────────────┘ │ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ Application Security │ │ - Input Validation │ │ - Output Encoding │ │ - Security Headers │ └────────────────────────────────┬────────────────────────────────┘ │ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ Data Security │ │ - Encryption at Rest │ │ - Encryption in Transit │ │ - Sensitive Data Handling │ └────────────────────────────────┬────────────────────────────────┘ │ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ Monitoring & Logging │ │ - Security Event Logging │ │ - Anomaly Detection │ │ - Audit Trail │ └─────────────────────────────────────────────────────────────────┘ ``` ## Authentication Security ### JWT Authentication 1. **Token Generation**: - JWTs are signed using RS256 (RSA Signature with SHA-256) - Private key is stored securely and rotated periodically - Tokens include standard claims (iss, sub, exp, iat) - Short expiration times (24 hours) with refresh token mechanism 2. **Token Validation**: - Signature verification using public key - Expiration validation - Issuer validation - Audience validation when applicable 3. **Token Storage**: - Tokens are stored in memory (not localStorage) in browser clients - Refresh tokens use HTTP-only cookies with secure flag - Anti-CSRF measures implemented for refresh token usage ### API Key Authentication 1. **Key Generation**: - Cryptographically secure random generation - 256-bit entropy minimum - Prefixed format for easy identification (`mcp_sk_*`) 2. **Key Storage**: - Only hashed versions stored in database - bcrypt hashing with appropriate work factor - Original key shown only once to user 3. **Key Validation**: - Constant-time comparison to prevent timing attacks - Rate limiting on API key endpoints - Automatic lockout after repeated invalid attempts ### Multi-factor Authentication (MFA) 1. **Supported Methods**: - Time-based One-Time Password (TOTP) - Email verification codes - WebAuthn/FIDO2 (future implementation) 2. **Implementation**: - MFA required for administrative actions - Optional for general user authentication - Recovery codes provided for backup access ## Authorization Controls ### Role-Based Access Control (RBAC) User roles define base permission levels: 1. **Organization Admin**: - Full control over organization resources - User management within organization - MCP service configuration and monitoring 2. **Developer**: - Create and use MCP service configurations - View organization-level usage analytics - Manage personal API keys and tokens 3. **Viewer**: - Use existing MCP services (read-only) - View personal usage history - No configuration capabilities ### Permission Scopes API keys and tokens can be further restricted with granular scopes: 1. **Service Scopes**: - `mcp:read`: Use MCP services (read operations) - `mcp:write`: Configure and modify MCP services - `mcp:admin`: Manage organizational MCP settings 2. **User Scopes**: - `user:read`: Read user profile information - `user:write`: Update user profile - `user:token`: Manage personal tokens 3. **Organization Scopes**: - `org:read`: View organization information - `org:write`: Update organization settings - `org:admin`: Manage organization users and billing ### Resource Ownership Validation All resource access is validated against ownership: 1. **User Resources**: - Personal tokens and API keys - User profile information - Personal usage logs 2. **Organization Resources**: - MCP service configurations - Organization settings - User management within organization 3. **Row-Level Security**: - Implemented at database level using Supabase RLS policies - Example policy: ```sql CREATE POLICY "Users can only access their own tokens" ON user_tokens FOR ALL USING (auth.uid() = user_id); ``` ## Data Protection ### Encryption at Rest 1. **Database Encryption**: - Transparent Data Encryption (TDE) at database level - Encrypted backups - Secure key management 2. **Application-Level Encryption**: - Sensitive fields encrypted before storage - Service-specific tokens encrypted with AES-256-GCM - Separate encryption keys for different data categories 3. **Key Management**: - Encryption keys stored in secure key management service - Automatic key rotation schedule - Access to keys restricted to application services ### Encryption in Transit 1. **HTTPS Enforcement**: - TLS 1.2+ required for all connections - Strong cipher suites - HSTS implementation - Certificate pinning for API clients 2. **API Communication**: - All API endpoints require HTTPS - Internal service communication encrypted - Secure WebSocket connections when applicable ### Sensitive Data Handling 1. **Data Classification**: - Clear classification of data sensitivity levels - Handling procedures based on classification - Access controls aligned with classification 2. **Secure Storage Practices**: - Sensitive data stored only when necessary - Automatic purging of unnecessary sensitive data - Secure deletion procedures 3. **Data Minimization**: - Collection limited to necessary information - Retention periods defined for different data types - Automatic data pruning based on retention policy ## Application Security ### Input Validation 1. **Validation Strategy**: - Server-side validation for all inputs - Schema-based validation using Zod - Type checking and sanitization - Rejection of unexpected inputs 2. **API Parameter Validation**: - Strong typing for all API parameters - Range and format validation - Content-type validation 3. **Prevention Controls**: - SQL injection prevention - XSS prevention - Command injection prevention - JSON parsing vulnerabilities mitigation ### Output Encoding 1. **Response Encoding**: - Context-appropriate encoding for all outputs - HTML encoding for web content - JSON encoding for API responses - Content-Type headers with charset 2. **Error Handling**: - Secure error messages (no sensitive information) - Consistent error format - Appropriate HTTP status codes ### Security Headers All API responses include security headers: ``` Strict-Transport-Security: max-age=31536000;
