play_playlist · Social Video MCP: Risk & Policy

WHAT IT DOES

What play_playlist does on Social Video

AI agents invoke play_playlist to trigger actions in Social Video. 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 play_playlist needs a policy

This tool launches or controls an external application (mpv player) to play video content. It triggers an external operation whose effects depend on the provided playlist URL or channel page argument. While not destructive or financial, it executes an external process/operation, placing it firmly in the Execute category.

play_playlist Rate-limited

play_playlist stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
