WHAT IT DOES

What play_audio does on ElevenLabs MCP Enhanced

AI agents invoke play_audio to trigger actions in ElevenLabs MCP Enhanced. 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 play_audio is rated High

Playing audio locally is an execution action that interacts with the host system's audio subsystem. It is not a pure read (it produces side effects on the local environment), not a write (no data is persisted), but it does trigger an external operation. Misuse could involve playing unexpected or harmful audio content, but blast radius is generally limited to the local session.

From the tool's definition 'Plays audio file locally' — triggers an external operation (local audio playback) with side effects on the host system

RECOMMENDED RULE

The rule that runs play_audio safely

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

play_audio Rate-limited

play_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.
