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

The first open-source Model Context Protocol (MCP) bridge connecting Antigravity (AGY) 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 Flash / Veo (VideoFX)—directly from your coding environment.

⚡ 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 directly during coding sessions.

• 🎵 Dynamic Soundtracks & Stems: Prompt Lyria for custom looping background music and combat SFX.

• 🎬 Cinematic Video & Cutscenes: Orchestrate video generation models for trailers, cutscenes, and animated backgrounds.

• 🔑 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)

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/config/mcp_config.json):

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

For Claude Desktop (claude_desktop_config.json):

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