# Echo3s MCP Server

An MCP (Model Context Protocol) server that gives any AI assistant deep knowledge about [Echo3s](https://echo3s.io) — the AI-powered platform that turns books into professional multi-voice audiobooks.

Connect this server to Claude, ChatGPT, or any MCP-compatible AI assistant, and it becomes a knowledgeable Echo3s expert that can answer questions about pricing, features, use cases, and how to get started.

## What is Echo3s?

Echo3s transforms books into audiobooks where **each character gets their own distinct AI voice**. Unlike single-voice TTS tools, Echo3s automatically detects characters, assigns unique voices, and produces full-cast audiobooks that sound like actual performances.

- **99% cheaper** than traditional narration ($30–$99 vs $3,000–$15,000)
- **50+ premium AI voices** from ElevenLabs
- **Arabic support** — one of the only platforms in the world that does this
- **100% rights retention** — your book, your audiobook, your money
