mcp-tts

MCP Server for TTS (Text-to-Speech)

What? 🤔

Adds Text-to-Speech to things like Claude Desktop and Cursor IDE.

It registers the existing TTS tools, plus voice_tts when voice-say is available on PATH:

• say_tts
• voice_tts (when available)
• elevenlabs_tts
• google_tts
• openai_tts

say_tts

Uses the macOS say binary to speak the text with built-in system voices

voice_tts

Uses the local voice-say CLI from Voice to run Qwen3-TTS through MLX. Voice needs no API key and keeps text and audio on the Mac. The model reloads for every invocation, so startup typically takes several seconds; prefer it for summaries and announcements rather than time-critical alerts.

The tool is registered only when voice-say is resolvable on PATH. Optional parameters are:

• voice: preset voice Ryan or Aiden
• tier: small for faster 0.6B synthesis or large for higher-quality 1.7B synthesis
• style: free-text delivery guidance
• describe: free-text voice design; forces the 1.7B model and cannot be combined with voice

Voice plays audio directly and does not support --output-dir; with --no-play, calls fail without launching voice-say.

[!WARNING] The Voice repository is currently private and will be released publicly soon, so the link requires access for now.

elevenlabs_tts

Uses the ElevenLabs text-to-speech API to speak the text with premium AI voices
