video_studio_render_video · LocalAnt MCP: Risk & Policy

WHAT IT DOES

What video_studio_render_video does on LocalAnt

AI agents invoke video_studio_render_video to trigger actions in LocalAnt. 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_studio_render_video needs a policy

This tool triggers execution of external media processing software (Remotion or FFmpeg) to produce a rendered video file. It is an Execute-category action because it runs computational processes with effects that depend on the provided arguments (source files, settings). While it produces a file (Write-like), the primary action is executing a rendering pipeline via third-party tools.

From the tool's definition 'Render a local upload-ready MP4 with Remotion primary or FFmpeg static-slide fallback' — executes a video rendering pipeline using external tools (Remotion/FFmpeg)
