WHAT IT DOES

What comprehensive_validation does on Netmiko MCP Server

AI agents invoke comprehensive_validation to trigger actions in Netmiko MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why comprehensive_validation needs a policy

Validation of network device configurations and connectivity implies sending commands to live Cisco devices via SSH (using Netmiko), actively probing interfaces, connectivity paths, and configuration state. This is not a passive read — it executes operational checks across the device.

From the tool's definition 'Perform comprehensive validation of all device configurations and connectivity' — triggers active validation checks across device configurations and connectivity tests on live network infrastructure
