WHAT IT DOES

What suno_track_extend does on Suno-MCP

AI agents invoke suno_track_extend to trigger actions in Suno-MCP. 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 suno_track_extend needs a policy

This tool triggers an external operation on Suno AI (via Playwright browser automation) to extend a track, which involves executing an action with real-world side effects. It is not purely a write in the traditional sense because it invokes an AI generation process through browser automation. It could consume Suno credits/quota.
