afx_audio_delay · vidMagik- MCP: Risk & Policy

WHAT IT DOES

What afx_audio_delay does on vidMagik-mcp

AI agents use afx_audio_delay to create or update resources in vidMagik-mcp — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your vidMagik-mcp environment.

WHY IT NEEDS A POLICY

Why afx_audio_delay needs a policy

This tool applies a delay effect to audio, which creates a modified version of the audio data. While the effect is reversible (the original audio is not deleted), the tool creates transformed audio output. This is a Write operation rather than Read (it modifies data), Execute (it's a specific audio effect, not arbitrary code execution), or Destructive (the original data is preserved).

From the tool's definition Tool name 'afx_audio_delay' and description 'Audio delay' indicate audio effect processing that modifies audio properties.
