suno_close_browser · Suno- MCP: Risk & Policy

WHAT IT DOES

What suno_close_browser does on Suno-MCP

AI agents invoke suno_close_browser 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_close_browser needs a policy

This tool terminates an active browser session managed by Playwright, which is an external process/resource operation. It executes a side-effecting action (killing the browser process and freeing resources) rather than simply reading data or writing persistent data. Misuse could disrupt ongoing music generation workflows by prematurely terminating the browser automation session.
