WHAT IT DOES

What video_studio_generate_audio does on LocalAnt

AI agents invoke video_studio_generate_audio 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.

RISK

Why video_studio_generate_audio is rated High

This tool executes external programs (VOICEVOX, macOS 'say', FFmpeg) on the local system to generate audio files. It triggers external operations whose effects depend on arguments, qualifying as Execute. Severity is medium as it runs local processes and produces files, but is not inherently destructive or financial.

RECOMMENDED RULE

The rule that runs video_studio_generate_audio safely

PolicyLayer is an MCP gateway: it sits between your AI agents and LocalAnt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For video_studio_generate_audio, this is the rule to start with:

video_studio_generate_audio Rate-limited

video_studio_generate_audio 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.
