video_record · Phantom MCP: Risk & Policy

WHAT IT DOES

What video_record does on Phantom

AI agents invoke video_record to trigger actions in Phantom. 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 video_record needs a policy

Recording video on a simulator/device is an external operation that triggers device functionality. It falls under Execute as it initiates a real-time capture process on connected hardware or emulators. The description is truncated, which lowers confidence slightly, but the tool name and context (mobile device automation server) clearly indicate video recording functionality.

From the tool's definition Tool name 'video_record' and partial description 'Enregistre une vidéo de l' (records a video of the...) indicate triggering a recording operation on a device/emulator

Verdict

video_record Rate-limited

video_record 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.
