mcp-kokoro

An MCP server for Kokoro TTS, enabling high-quality text-to-speech capabilities for MCP clients.

Overview

This server provides tools to generate spoken audio from text using the Kokoro model. It is designed to be used with the Model Context Protocol (MCP), allowing AI agents to "speak" to the user.
