WHAT IT DOES

What suno_wait_for_songs does on Suno MCP

WHY IT NEEDS A POLICY

Why suno_wait_for_songs needs a policy

This tool executes an external operation (music generation) and polls/waits for its completion, which are characteristic of Execute category actions. While music generation itself is benign, the tool commits computational resources and API calls based on provided parameters.

From the tool's definition Tool performs an asynchronous wait operation that blocks execution until external API (Suno) completes song generation.
