### Device Config Workflow
```mermaid
sequenceDiagram
participant AI as AI Agent
participant MCP as MCP Handler
participant TM as Template Renderer
participant DP as Device Discovery
participant NR as Nornir
participant NM as Netmiko
participant D as Device Console
Note over AI: Decide: template or direct commands?
alt Direct commands
AI->>MCP: device_config_send(config_commands=[...])
else Jinja2 template
AI->>MCP: device_config_send(template + vars)
MCP->>TM: Render template per device
TM->>TM: Jinja2.render(**vars)
TM-->>MCP: device_configs with rendered commands
end
MCP->>DP: get_device_ports_from_topology()
DP-->>MCP: hosts_data (console port, device_type)
Note over MCP: Prepare Nornir inventory
MCP->>NR: InitNornir(hosts, threaded runner)
par Device 1 to N (parallel, max 10)
NR->>NM: netmiko_send_config(commands)
NM->>D: telnet/SSH console session
D-->>NM: command output
NM-->>NR: execution result
end
NR-->>MCP: aggregated results
MCP-->>AI: per-device results with output
```
