Overview

This MCP server enables interaction with Google Gemini services without requiring API keys, instead using Chrome browser cookies for authentication. It supports advanced features like automatic 2x upscaling of generated images, lossless watermark removal using reverse alpha blending, and file analysis capabilities. The server exposes multiple tools including image generation, file upload, URL analysis, and multi-turn chat functionality.

When to choose this

Choose this when you want to access Google Gemini's capabilities without dealing with API keys or authentication hassles, especially for image generation with automatic upscaling and watermark removal.

When NOT to choose this
