Use when you need to create a structured plan for music generation with defined styles, sections, and durations. The generated plan can be used as input for actual music generation or as a template for variations.

Creates an ElevenLabs AudioNative project, generating an embeddable audio player from a provided content file using text-to-speech, allowing customization of player appearance, audio settings, and conversion options.

Returns a list of shared voices similar to the provided audio sample. Use when you need to find voice matches based on audio characteristics. If neither similarity_threshold nor top_k is provided, default values will be applied.

Tool to generate a time-limited single-use token with embedded authentication for frontend clients. Use when you need secure, temporary access tokens for WebSocket connections or real-time services.

Tool to create a new webhook for the workspace with specified authentication type. Use when you need to configure a webhook endpoint to receive notifications from ElevenLabs. The webhook_secret returned should be stored securely for verifying webhook authenticity.
