send_config · Netmiko MCP Server MCP: Risk & Policy

WHAT IT DOES

What send_config does on Netmiko MCP Server

AI agents invoke send_config 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 send_config needs a policy

The tool name 'send_config' strongly implies it sends configuration commands to network devices via SSH. Configuration changes on network devices (routers, switches, firewalls) can have wide blast radius effects — disrupting connectivity, altering security policies, or causing outages. This falls under Execute as it triggers external operations on remote devices.

From the tool's definition Tool name 'send_config' on a server described as 'supporting command execution, configuration management' via SSH using Netmiko; sibling tools include 'send_command' and 'send_config_parallel'

Verdict

send_config Rate-limited

send_config stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
