next_video · Social Video MCP: Risk & Policy

WHAT IT DOES

What next_video does on Social Video

AI agents invoke next_video 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 next_video needs a policy

This tool triggers an external operation (controlling mpv media player playback) by advancing to the next video. It doesn't read data, write/modify stored data, or delete anything — it executes a player control command. The blast radius is low since it only affects local media playback state.

Verdict

next_video Rate-limited

next_video 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.
