No instance creation/termination capabilities (read/manage existing only)
Single compartment operations (no cross-compartment queries)
No instance console connection access
No instance pool or configuration management

💾 Storage & Networking:

No block storage volume management
Limited networking operations (read-only VNIC information)
No VCN/subnet management capabilities
No load balancer integration

📊 Monitoring & Cost:

No instance metrics or performance data
No cost tracking or billing information
No resource optimization recommendations

🚀 Planned Enhancements

Phase 1 (High Priority)

Instance termination with safety safeguards
Multi-compartment support and search
Basic cost information and estimates
Instance console connection management
Block storage volume operations

Phase 2 (Medium Priority)

Instance creation and configuration templates
Load balancer backend management
Instance metrics and performance monitoring
Advanced networking operations (VCN management)
Resource tagging and metadata operations

Phase 3 (Future)

Infrastructure as Code generation (Terraform)
Container instance and OKE cluster support
Advanced cost optimization recommendations
Disaster recovery orchestration
Automated resource lifecycle policies

📊 Current Test Results

✅ Successfully tested with production OCI tenancy:

Instance Discovery

13 running instances discovered
Instance names: ArkimeGOAD, Caldera, Ludus, Suricata, TPOT, Victim1, braavos, etc.
Shapes: VM.Standard.E4.Flex, VM.Standard.E5.Flex, VM.Standard.E6.Flex
All with complete OCIDs and lifecycle states

Network Information

Private IPs: 192.168.56.x, 192.168.57.x networks
Public IPs: Available where configured
Hostnames: arkimegoad, ludus, etc.
MAC addresses: Complete network interface details
Security groups: NSG associations included

Performance

Primary Method: OCI Python SDK
Response time: ~500ms for 13 instances with network info
Fallback: CLI method available for compatibility
LLM-friendly: Optimized JSON structure for AI consumption

🔄 SDK vs CLI Approach

Primary: OCI Python SDK

✅ Direct API access to OCI Core Services
✅ Type-safe responses with proper data structures
✅ Better performance with connection pooling
✅ Rich metadata including detailed configurations
✅ Network information via VirtualNetworkClient
✅ Real-time data with immediate API responses

Fallback: OCI CLI

✅ Universal compatibility where SDK isn't available
✅ Same data format for seamless switching
⚠️ Limited network info (requires additional calls)
⚠️ JSON parsing overhead

🎯 LLM-Friendly JSON Format

Key Design Principles:

Human-readable summaries: Every response includes a summary field
Consistent structure: All responses follow the same pattern
Clear success indicators: success boolean for easy parsing
Comprehensive data: Both summary and detailed data included
ISO timestamps: Standardized time format
Error handling: Consistent error response format

Response Structure:

{
  "success": true|false,
  "summary": "Human-readable description",
  "count": 13,
  "method": "OCI Python SDK|OCI CLI",
  "data_field": [...],
  "retrieved_at": "2025-07-30T09:42:30Z",
  "error": "Error message if failed"
}
