- Encrypted token storage (Fernet encryption)
- Tokens refreshed 60 seconds before expiration
- No hardcoded credentials

### Authorization & Consent
- Permission-based authorization (READ, WRITE, ADMIN, SENSITIVE)
- User consent for high-risk operations
- Audit logging for all authorization decisions
- Consent expiration after 60 minutes

### Input Validation & SQL Protection
- Type-based input validation
- SQL injection prevention (15+ attack patterns)
- Read-only query enforcement
- Query complexity limits

### Data Privacy
- PII and credential redaction
- Pattern-based sensitive data detection
- Partial hostname redaction
- Safe logging without secret exposure

## ⚡ Performance Features

### Intelligent Caching System

**Performance Improvements**:
- **60-80% reduction** in API call response times
- **Category-based TTL**: Metadata (5 min), Data (1 min), Health (30 sec)
- **LRU eviction** for memory management
- **Cache statistics** for monitoring

**Search Tool Optimization**:
- `search_catalog`: Caches catalog search results (5 min TTL)
- `search_repository`: Caches repository search (5 min TTL)
- All metadata tools benefit from caching

**Cache Control**:
```bash
# Enable/disable caching
CACHE_ENABLED=true  # default
MAX_CACHE_SIZE=1000  # entries
```
