WHAT IT DOES

What acp_restart_session does on Ambient Code Platform MCP Server

AI agents invoke acp_restart_session to trigger actions in Ambient Code Platform 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 acp_restart_session needs a policy

Restarting a session is an operational action that initiates processes and state changes in a remote Kubernetes environment. While not destructive (data is preserved) or financial, it is an Execute-class tool because it triggers external operations whose outcomes depend on runtime conditions. The dry-run mode mitigates some risk but does not change the fundamental classification of the live execution path.

From the tool's definition Tool name 'acp_restart_session' and description 'Restart a stopped session' indicate initiation of a system operation.
