🧪 Google Labs & Flow MCP Server (google-labs-mcp)

The first open-source Model Context Protocol (MCP) bridge connecting Antigravity (AGY), Claude, and AI coding agents directly to Google Labs and Google Flow.
Harness DeepMind's bleeding-edge creative models—Imagen 3 (ImageFX), Lyria (MusicFX), and Gemini Omni 1.1 Flash / Veo 2 (VideoFX)—directly from your coding environment with automated post-production!

⚡ Why This Matters

AI coding assistants are typically confined to writing text files and code snippets. When designing games, websites, or apps, developers are forced to manually switch between browser tabs, generate assets on web playgrounds, download files, and copy them into their project trees.

google-labs-mcp closes that gap. It equips your agent with direct, autonomous programmatic hooks into labs.google and flow.google.com:

• 🎨 Instant Concept Art & Textures: Request high-resolution imagery via Imagen 3 & Nano Banana Pro directly during coding sessions.

• 🎵 Dynamic Soundtracks & Loops: Prompt Lyria for custom background music and audio stems.

• 🎬 Cinematic Video & Multi-Shot Sequences: Orchestrate multi-camera storyboard scenes using Gemini Omni 1.1 Flash & Veo 2.

• 🎞️ Post-Production Media Muxing: Automatically combine synthesized video and audio into a finished master MP4 with AAC 192k audio using portable FFmpeg.

• 📋 Visual Storyboards: Export dark-mode HTML storyboard galleries to preview scene progressions and cutscenes.

• 🔑 Zero-Friction Authentication: Automatically attaches to your active Chrome browser session (inheriting Google One / Ultra plan privileges) with zero OAuth hassle or API quota surcharges.

🛠️ Tools Exposed to MCP Clients

🚀 Quick Start Guide

1. Prerequisites

• Node.js v18+ (Tested on v24)

• Google Chrome browser installed

• A Google account (works with standard accounts, with full prioritized compute on Ultra / Google One)

• (Optional for media muxing): Run tools\download_ffmpeg.bat to install portable FFmpeg with 1 click.

2. Installation

git clone https://github.com/ssfdre38/google-labs-mcp.git
cd google-labs-mcp
npm install

3. One-Click Session Launch

Run the session launcher:

start_labs_session.bat

This launches Chrome with --remote-debugging-port=9222 and a dedicated profile (~/.gemini/labs_chrome_profile). Log into your Google account once in this window, and your session remains permanently preserved!

4. Register in Your MCP Client

For Google Antigravity (~/.gemini/settings.json):

{
  "mcpServers": {
    "google-labs": {
      "command": "node",
      "args": ["C:\\path\\to\\google-labs-mcp\\index.js"],
      "timeout": 60000
    }
  }
}

For Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "google-labs": {
      "command": "node",
      "args": ["C:\\path\\to\\google-labs-mcp\\index.js"]
    }
  }
}
