sound_effects · ElevenLabs MCP: Risk & Policy

WHAT IT DOES

What sound_effects does on ElevenLabs

AI agents invoke sound_effects to trigger actions in ElevenLabs. 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 sound_effects needs a policy

While this tool does not destructively delete data or move money, it executes code/external operations (triggering ElevenLabs' audio generation API) based on user input. The blast radius is medium because misuse could result in unwanted audio generation, API quota exhaustion, or potential abuse of the service, but cannot directly damage data or cause financial harm.

From the tool's definition Tool generates sound effects from text descriptions, which involves executing external API calls to ElevenLabs' generative models.
