## 🚀 Componenti Chiave del Sistema

### 1️⃣ MCP Integration (`src/datacenter_docs/mcp/client.py`)

**Cosa fa**: Connette il sistema a tutti i dispositivi datacenter via MCP Server

**Features**:
- ✅ Query VMware vCenter (VM, host, datastore)
- ✅ Query Kubernetes (nodes, pods, services)
- ✅ Query OpenStack (instances, volumes)
- ✅ Exec comandi su network devices (Cisco, HP, ecc.)
- ✅ Query storage arrays (Pure, NetApp, ecc.)
- ✅ Retrieve monitoring metrics
- ✅ Retry logic con exponential backoff
- ✅ Async/await per performance

**Esempio uso**:
```python
async with MCPClient(server_url="...", api_key="...") as mcp:
    vms = await mcp.query_vmware("vcenter-01", "list_vms")
    pods = await mcp.query_kubernetes("prod-cluster", "all", "pods")
```

### 2️⃣ API per Ticket Resolution (`src/datacenter_docs/api/main.py`)

**Cosa fa**: API REST che riceve ticket e genera automaticamente risoluzione

**Endpoints Principali**:
```
POST   /api/v1/tickets              # Crea e processa ticket
GET    /api/v1/tickets/{id}         # Status ticket
POST   /api/v1/documentation/search # Cerca docs
GET    /api/v1/stats/tickets        # Statistiche
GET    /health                       # Health check
GET    /metrics                      # Prometheus metrics
```

**Workflow**:
1. Sistema esterno invia ticket via POST
2. API salva ticket in database
3. Background task avvia DocumentationAgent
4. Agent cerca docs rilevanti con semantic search
5. Claude analizza e genera risoluzione
6. API aggiorna ticket con risoluzione
7. Sistema esterno recupera risoluzione via GET

**Esempio integrazione**:
```python
import requests

response = requests.post('https://docs.company.local/api/v1/tickets', json={
    'ticket_id': 'INC-12345',
    'title': 'Storage full',
    'description': 'Datastore capacity at 95%',
    'category': 'storage'
})

resolution = response.json()
print(f"Resolution: {resolution['resolution']}")
print(f"Confidence: {resolution['confidence_score']}")
```

### 3️⃣ Chat Agent Agentico (`src/datacenter_docs/chat/agent.py`)

**Cosa fa**: AI agent che cerca autonomamente nella documentazione per aiutare l'utente

**Features**:
- ✅ Semantic search su documentazione (ChromaDB + embeddings)
- ✅ Claude Sonnet 4.5 per reasoning
- ✅ Ricerca autonoma multi-doc
- ✅ Conversational memory
- ✅ Confidence scoring
- ✅ Related docs references

**Metodi Principali**:
- `search_documentation()` - Semantic search
- `resolve_ticket()` - Auto-risoluzione ticket
- `chat_with_context()` - Chat interattiva
- `index_documentation()` - Indexing docs

**Esempio**:
```python
agent = DocumentationAgent(mcp_client=mcp, anthropic_api_key="...")

# Risolve ticket autonomamente
result = await agent.resolve_ticket(
    description="Network connectivity issue between VLANs",
    category="network"
)

# Chat con contesto
response = await agent.chat_with_context(
    user_message="How do I check UPS battery status?",
    conversation_history=[]
)
```

### 4️⃣ Frontend React (`frontend/src/App.jsx`)

**Cosa fa**: UI web per interazione utente
