📌Overview

Purpose: This framework serves to integrate ElevenLabs' text-to-speech API through a Model Context Protocol (MCP) server, enabling efficient voice generation management.

Overview: The ElevenLabs MCP Server comprises both server and client components, designed for seamless interaction with ElevenLabs’ text-to-speech functionalities. It allows users to generate audio from text, manage various voice settings, and maintain a history of voice generation tasks via a user-friendly web interface built with SvelteKit.

Key Features:

• Audio Generation: Converts text to audio using ElevenLabs API, facilitating diverse applications in voice synthesis.

• Multi-Voice Support: Enables users to utilize multiple voices and manage different script parts for more dynamic audio production.

• Persistent History: Employs an SQLite database to store generation histories, allowing for easy access to previous audio output.

• Web Client: Comes with a sample SvelteKit MCP Client, simplifying the user experience for tasks such as text-to-speech conversion and voice history playback.
