Features

  • Implements an MCP server for TTS functionality.

  • Connects to the Groq API (https://api.groq.com/openai/v1/audio/speech) for generating lifelike audio from text.

  • Provides a generate_speech tool accessible via the MCP protocol.

  • Supports multiple audio output formats (wav, mp3, aac, opus, flac).

  • Uses @tropicbliss/symphonia to play the generated audio directly on the server machine (optional).

  • Requires a Groq API key set as an environment variable (GROQ_API_KEY).
