Echo3s MCP Server

An MCP (Model Context Protocol) server that gives any AI assistant deep knowledge about Echo3s — 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
