API keys stored as SHA-256 hashes in database - Hostaway credentials encrypted in organization records - No secrets in logs or responses - Proper HTTP status codes for auth failures ### Rate Limiting ⚠️ **Configuration** (from environment): - IP-based: 15 requests per 10 seconds - Account-based: 20 requests per 10 seconds - Max concurrent: 50 requests **Issue**: Rate limit headers not visible in responses (may be internal only) **Recommendation**: Expose rate limit headers to clients: ``` X-RateLimit-Limit-IP: 15 X-RateLimit-Remaining-IP: 14 X-RateLimit-Reset-IP: 1698574800 X-RateLimit-Limit-Account: 20 X-RateLimit-Remaining-Account: 19 X-RateLimit-Reset-Account: 1698574800 ``` ### Input Validation ✅ - Pydantic models enforce type safety - FastAPI validates all request payloads - 422 status code for validation errors - Detailed error messages (safe for production) --- ## Performance Analysis ### Response Time Benchmarks | Endpoint | Average Time | Status | |----------|-------------|--------| | /health | 0.342s | Excellent | | / (root) | ~0.3s | Excellent | | /openapi.json | ~0.3s | Excellent | | /auth/authenticate | ~1-2s | Good (external API call) | ### Server Capacity **Observed Metrics**: - Uptime: 9.8 days (stable) - Context protection active: Yes - Zero oversized events: Good memory management - Average latency: 0ms (minimal internal processing) **Estimated Capacity** (based on rate limits): - IP-level: 90 requests/minute per IP - Account-level: 120 requests/minute per account - Concurrent: Up to 50 simultaneous connections --- ## Issues Identified ### Critical Issues None ### High Priority 1. **Multi-Tenant Database Dependency** (Impact: HIGH) - **Issue**: All data endpoints require valid X-API-Key from Supabase database - **Impact**: Cannot test without database access and organization setup - **Recommendation**: Document complete setup process including: - Supabase database initialization - Organization creation - API key generation - Credential encryption workflow 2. **Rate Limit Headers Missing** (Impact: MEDIUM) - **Issue**: Clients cannot determine remaining request quota - **Impact**: Risk of hitting rate limits unexpectedly - **Recommendation**: Add standard rate limit headers to responses ### Medium Priority 3. **MCP Tool Documentation** (Impact: MEDIUM) - **Issue**: MCP tool schemas not documented in OpenAPI spec - **Impact**: Developers must read code to understand MCP capabilities - **Recommendation**: Add MCP-specific documentation page ### Low Priority 4. **Health Check Details** (Impact: LOW) - **Issue**: Context protection metrics all showing zero - **Impact**: Cannot verify middleware is functioning under load - **Recommendation**: Add sample load to verify metrics update correctly --- ## Recommendations ### For Production Deployment 1. **Database Setup Documentation** - Create comprehensive guide for Supabase setup - Include SQL migration scripts - Document credential encryption process 2. **Monitoring & Observability** - Add structured logging with correlation IDs (already implemented) - Implement metrics export (Prometheus/StatsD) - Set up alerting for rate limit breaches 3. **Rate Limiting** - Expose rate limit headers to clients - Consider implementing exponential backoff guidance - Add rate limit documentation to API docs 4. **Error Messages** - Current error messages are clear and production-safe - Consider adding correlation IDs to error responses - Add troubleshooting links to error responses ### For Testing 1. **Integration Test Suite** - Create end-to-end test with database fixtures - Mock Supabase responses for unit tests - Add MCP protocol compliance tests 2. **Load Testing** - Test rate limiting under concurrent load - Verify token refresh mechanism under stress -
