WHAT IT DOES

What system_manage_volume does on PC-Control MCP Server

AI agents invoke system_manage_volume to trigger actions in PC-Control 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 system_manage_volume needs a policy

This tool modifies a system resource (audio volume) rather than just reading it. It's not destructive or financial, and while it writes to a system setting, it's best classified as Execute since it triggers an OS-level operation. The blast radius is low as misuse would at most cause audio annoyance or disruption, not data loss or financial harm.

From the tool's definition 'Control system audio volume' — actively changes system audio settings, triggering an external operation on the OS audio subsystem.
