navigate_to · Chrome DevTools MCP Server MCP: Risk & Policy

WHAT IT DOES

What navigate_to does on Chrome DevTools MCP Server

AI agents invoke navigate_to to trigger actions in Chrome DevTools 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

navigate_to triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
