ixia_stop · Grafana MCP Server MCP: Risk & Policy

WHAT IT DOES

What ixia_stop does on Grafana MCP Server

AI agents invoke ixia_stop to trigger actions in Grafana 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 ixia_stop needs a policy

This tool executes a command to halt traffic generation on network test equipment (Ixia replayer). While not destructive of data and not financial, it triggers an external operation whose effects depend on which replayer is specified. Stopping traffic generation mid-test could disrupt ongoing network validation, performance testing, or incident response scenarios.

From the tool's definition Tool description states 'Stop the Ixia traffic replayer. Halts all traffic generation on the specified replayer.' The verb 'Stop' and 'Halts' indicate active control of external network traffic generation infrastructure.
