Gaudio Lab Audio AI

npm version Glama score License: MIT

MCP server for Gaudio Lab Audio AI API. Separate vocals, instruments, dialogue, music, effects from any audio/video — or sync lyrics to timestamps — all through natural language in your AI tools.

Works with Claude, ChatGPT, Cursor, VS Code, GitHub Copilot, and any MCP-compatible client.

Get Your API Key

1. Sign up at Gaudio Developers
2. Create a project and get your API key from the dashboard

Quick Start

Add to your MCP client config:

{
  "mcpServers": {
    "gaudio": {
      "command": "npx",
      "args": ["-y", "@gaudiolab/mcp-developers"],
      "env": {
        "GAUDIO_API_KEY": "your-api-key-here"
      }
    }
  }
}

Then just ask in natural language:

• "Separate the vocals from this file"
• "Extract the dialogue from this video"
• "Sync these lyrics to this song"
• "What models are available?"
• "How many credits do I have left?"
