- Accesso management network
```

### Setup Iniziale

1. **Clone repository**
```bash
git clone https://github.com/company/datacenter-docs.git
cd datacenter-docs
```

2. **Configura credenziali**
```bash
# Crea file MCP config
cp config/mcp_config.example.json config/mcp_config.json
# Edita con credenziali reali
vim config/mcp_config.json

# Crea .env per Docker

SWITCH_PASSWORD=your_password
STORAGE_API_KEY=your_api_key
EOF
```

3. **Build e avvia servizi**
```bash
# Build documentazione
./scripts/build-docs.sh

# Avvia con Docker Compose
docker-compose up -d

# Verifica health
curl http://localhost:8000/health
curl http://localhost:8001/methods
```

4. **Accedi alla documentazione**
```
http://localhost:8000/docs/
http://localhost:8000/api/docs  (API Swagger)
http://localhost:8001/docs      (MCP Swagger)
```

## 🔄 Workflow Automazione

### 1. Generazione Documentazione
```bash
# LLM genera/aggiorna template
python3 main.py --section 01

# Commit su Git
git add templates/
git commit -m "docs: update infrastructure section"
git push origin main
```

### 2. CI/CD Pipeline
```
Push to main
  ↓
GitHub Actions triggered
  ↓
├─ Lint & Validate
├─ Build MkDocs
├─ Build Docker Image
├─ Security Scan
└─ Deploy to Production
  ↓
Documentation live!
```

### 3. Accesso Documentazione
```
User → Nginx → FastAPI → MkDocs Site
                      ↓
                   API REST
                      ↓
                LLM-optimized
```

## 🔌 API Usage

### Python Client Example
```python
import requests

# Get all sections
r = requests.get('http://localhost:8000/api/v1/sections')
sections = r.json()

for section in sections:
    print(f"{section['title']}: {section['token_estimate']} tokens")

# Get specific section
r = requests.get('http://localhost:8000/api/v1/sections/02_networking')
content = r.json()
print(content['content'])

# LLM-optimized content
r = requests.get('http://localhost:8000/api/v1/llm-optimized/02_networking')
llm_data = r.json()
print(f"Ready for LLM: {llm_data['token_count']} tokens")
```

### cURL Examples
```bash
# Health check
curl http://localhost:8000/health

# Get summary
curl http://localhost:8000/api/v1/summary | jq

# Search
curl "http://localhost:8000/api/v1/search?q=vmware" | jq

# Get section as HTML
curl "http://localhost:8000/api/v1/sections/03_server_virtualizzazione?format=html"
```

## 🤖 MCP Usage

### Python MCP Client
```python
import asyncio
import requests

async def query_infrastructure():
    base_url = 'http://localhost:8001'
    
    # List available methods
    r = requests.get(f'{base_url}/methods')
    print(r.json())
    
    # Execute SSH command
    r = requests.post(f'{base_url}/execute/ssh', json={
        'connection_name': 'switch-core-01',
        'command': 'show version'
    })
    result = r.json()
    print(f"Output: {result['output']}")
    
    # SNMP query
    r = requests.post(f'{base_url}/execute/snmp/get', json={
        'connection_name': 'ups-01',
        'oid': '.1.3.6.1.2.1.33.1.2.1.0'
    })
    ups_status = r.json()
    print(f"UPS Status: {ups_status['output']}")

asyncio.run(query_infrastructure())
```

## 🔐 Security

### Access Control
```yaml
Documentation (port 8000):
  - Public read access (internal network)
  - API key for external access

MCP Server (port 8001):
  - Internal network only
  - No external exposure
  - Audit logging enabled
  - Read-only operations
```

### Secrets Management
```bash
# Use environment variables
export VCENTER_PASSWORD="..."
export SWITCH_PASSWORD="..."

# Or use Docker secrets
docker secret create vcenter_pass vcenter_password.txt

# Or use HashiCorp Vault
vault kv get -field=password datacenter/vcenter
```

### Network Security
```bash
# Firewall rules
# Allow: Management network → MCP Server
# Allow: Internal network → Documentation
# Deny: External → MCP Server
# Allow: External → Documentation (with auth)
```

## 📊 Monitoring

### Health Checks
```bash
# FastAPI health
curl http://localhost:8000/health

# MCP health
curl http://localhost:8001/methods

### Logs
```bash
# Application logs
docker-compose logs -f docs-server

## 🔍 Troubleshooting

### Common Issues

**Port già in uso**
```bash
# Check what's using port
sudo lsof -i :8000
sudo lsof -i :8001

# Stop conflicting service
sudo systemctl stop service_name
```

**Docker build failed**
```bash
# Clean build
docker-compose build --no-cache docs-server

# Check logs
docker-compose logs docs-server
```

**MCP connection errors**
```bash
# Test connectivity
telnet switch.domain.local 22
snmpget -v2c -c public ups.domain.local .1.3.6.1.2.1.1.1.0

# Check config
cat config/mcp_config.json | jq

# Test connection
curl -X GET http://localhost:8001/test/switch-core-01
```

**Documentation not updating**
```bash
# Rebuild docs
./scripts/build-docs.sh

# Force rebuild
docker-compose down
docker-compose up -d --build

# Check pipeline
# Go to GitHub Actions and check logs
```
