WHAT IT DOES

What jenkins_toggle_node_offline does on Mcp Jenkins

AI agents invoke jenkins_toggle_node_offline to trigger actions in Mcp Jenkins. 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
