What is Gemini Image Generation MCP Server?

It is a Model Context Protocol (MCP) server that provides image generation capabilities using Google's Gemini 2 API. Designed for developers and Claude Desktop users who want to generate images directly from MCP-compatible tools.

How to use Gemini Image Generation MCP Server?

Obtain a Gemini API key from Google AI Studio, then configure Claude Desktop by adding the server entry to its config file with the GEMINI_API_KEY environment variable.

Frequently asked questions

What does this server do?

It acts as an MCP-compatible bridge that sends image generation requests to Google’s Gemini 2 experimental API and returns the resulting images.

What are the runtime requirements?

You need Node.js, npm, a valid Google Gemini API key, and an internet connection. The server runs over stdio via the MCP transport.

Where does generated image data live?

Images are generated remotely by Google’s Gemini API; the server only passes requests and responses. No persistent storage is handled by the server.

Is the image generation feature stable?

The server uses the **experimental** image generation feature of Gemini 2, so behavior may change. Ensure you have appropriate API access from Google.

How is authentication handled?

Authentication is done via a `GEMINI_API_KEY` environment variable set in the MCP server configuration or in a `.env` file.
