What is Banana Image MCP?

Banana Image MCP is an AI image generation server based on the Model Context Protocol (MCP), specifically designed for Claude Desktop. It allows you to generate high-quality images directly by having a natural language conversation with Claude. Whether it's a simple conceptual sketch or a professional 4K artwork, just tell Claude what you want, and it can create it for you.

How to use Banana Image MCP?

It's very easy to use: 1) Get a free Gemini API key; 2) Add server settings to the Claude Desktop configuration; 3) Restart Claude Desktop; 4) Start generating images using natural language. The entire setup process can be completed in just a few minutes.

Use cases

Suitable for users who need to quickly create visual content, including content creators, marketers, designers, product managers, educators, etc. Whether it's social media images, product prototypes, conceptual art, or technical diagrams, it can be easily generated.

Main features

4K Ultra HD output
Use the Pro model to generate images up to 3840 pixels, suitable for professional work, marketing materials, and printed materials
Dual model support
The Flash model (2 - 3 seconds, up to 1024px) is used for rapid iteration; the Pro model (5 - 8 seconds, up to 4K) is used for the final product
Intelligent model selection
The server automatically selects the best model based on your prompt. Say 'Quick sketch' to use the Flash model, say '4K professional' to use the Pro model
Google search grounding
The Pro model uses real-world knowledge from Google search to generate more accurate and fact-based images
Flexible aspect ratios
Supports all common ratios: 1:1, 16:9, 9:16, 4:3, 3:2, 21:9, etc.
Natural language editing
Edit existing images using simple text commands, such as 'Make the sky more dramatic' or 'Remove the background'
Advantages
Zero setup complexity - Just add the API key to start generating
Production-ready - Built on the FastMCP framework, fully tested, and supports CI/CD
Best quality - Utilizes Gemini's most advanced image model, supporting 4K
Intelligent defaults - Automatically selects the model based on the prompt
Real-world knowledge - Google search grounding ensures accurate and realistic images
Limitations
Requires a Google Gemini API key (free but requires registration)
The Pro model has a longer generation time (5 - 8 seconds)
Some features (such as Google search grounding) are only available for the Pro model
Requires Claude Desktop or other MCP-compatible clients
