mcp-tts vs xiaozhi-esp32-server
mcp-tts: `mcp-tts` is an MCP server that integrates various Text-to-Speech providers, including local macOS `say` and cloud APIs like ElevenLabs, Google TTS, and OpenAI TTS, into AI agent environments. It enables AI agents within tools like Claude Desktop and Cursor IDE to verbalize plans, summaries, and alerts, enhancing interactive communication.; xiaozhi-esp32-server: This project develops a smart terminal software and hardware system based on human-machine symbiosis intelligence, serving as a backend for the open-source smart hardware project xiaozhi-esp32. It is implemented in Python, Java, and Vue, supporting various protocols and features like voiceprint recognition and a knowledge base.

TL;DR
mcp-ttsVoice / Speech · ★ 74
Add Text-to-Speech capabilities to AI agent development environments (e.g., Claude Desktop, Cursor IDE) for interactive feedback.

When to choose:
- You own xiaozhi-esp32 hardware and want to host your own backend instead of a shared one.
- You want MQTT+UDP or WebSocket, MCP endpoints, voiceprint recognition and a knowledge base.
- You want a choice between a minimal no-database install and a full install with a web console and multi-user management.
When to skip:
- You have no ESP32 device: it is not useful without compatible hardware.
- You need production use: the README says it is incomplete and has not passed a network security evaluation.
- You cannot work from mainly Chinese documentation.
