Basic information

Config

Add this server to your MCP-compatible client using the configuration below.

{
  "mcpServers": {
    "nano-banana": {
      "command": "npx",
      "args": [
        "nano-banana-mcp"
      ],
      "env": {
        "GEMINI_API_KEY": "your-gemini-api-key-here"
      }
    }
  }
}

Tools

Configure your Gemini API token for nano-banana image generation

Generate a NEW image from text prompt. Use this ONLY when creating a completely new image, not when modifying an existing one.

Edit a SPECIFIC existing image file, optionally using additional reference images. Use this when you have the exact file path of an image to modify.

Check if Gemini API token is configured

Continue editing the LAST image that was generated or edited in this session, optionally using additional reference images. Use this for iterative improvements, modifications, or changes to the most recent image. This automatically uses the previous image without needing a file path.

Get information about the last generated/edited image in this session (file path, size, etc.). Use this to check what image is currently available for continue_editing.

FAQ from Nano Banana Mcp

What are the dependencies or runtime requirements?

Node.js 18.0.0 or higher and a Gemini API key from Google AI Studio are required.

How do I configure my API key?

You can set it as an environment variable in your MCP client config (recommended), as a system environment variable (GEMINI_API_KEY), or use the configure_gemini_token tool to create a local .nano-banana-config.json file.

Where are generated images saved?

Images are saved to platform-specific directories: %USERPROFILE%\Documents\nano-banana-images\ on Windows, ./generated_imgs/ on macOS/Linux, or ~/nano-banana-images/ when run from system paths.

What editing features does it support?

You can edit a specific image file with edit_image, continue editing the last generated/edited image with continue_editing, and optionally supply reference images for style transfer.

Is the API key stored securely?

The recommended method keeps the key in your MCP client’s environment config, which is contained within the MCP configuration. System environment variables and a local config file are also supported, with the config file automatically ignored by Git and NPM.
