Imagen 3 MCP server

Imagen3-MCP is an image generation tool based on Google's Imagen 3.0 that provides services through the Model Control Protocol (MCP). This tool allows you to generate high-quality, photorealistic images from text prompts using Google's powerful Imagen 3.0 model.

Requirements

• A valid Google Gemini API key

Installation

Download the Executable

1. Download the latest executable file from GitHub Releases
2. Place the downloaded executable anywhere in your system
   • Example: C:\bin\imagen3-mcp.exe

Configuration

Cherry Studio Setup

Configure Imagen3-MCP in Cherry Studio with the following settings:

1. In the Command field, enter the path to the executable:

   C:\bin\imagen3-mcp.exe
   

2. Set environment variables:

   • Required: Set GEMINI_API_KEY to your Google Gemini API key
   • Optional: Set BASE_URL to a proxy address if needed
     • Example: https://lingxi-proxy.hamflx.dev/api/provider/google
     • Note: While a proxy may help with GFW issues, you may still need a VPN to bypass Google's IP restrictions

Cursor Setup

To configure Imagen3-MCP in Cursor, add the following to your configuration:

{
  "mcpServers": {
    "imagen3": {
      "command": "C:\\bin\\imagen3-mcp.exe",
      "env": {
        "GEMINI_API_KEY": "<YOUR_GEMINI_API_KEY>"
      }
    }
  }
}

Replace <YOUR_GEMINI_API_KEY> with your actual Google Gemini API key.

Usage Examples

Imagen3-MCP can generate detailed, photorealistic images based on text prompts. Here are some example prompts you can try:

• "A running Jack Russell Terrier, telephoto lens, sunlight filtering through the dog's fur, photorealistic quality"
• "A high-tech apple"

After setup, you can send prompts through your configured MCP client (Cherry Studio or Cursor), and Imagen3-MCP will generate the corresponding images using Google's Imagen 3.0 technology.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "imagen3" '{"command":"C:\\bin\\imagen3-mcp.exe","env":{"GEMINI_API_KEY":"<GEMINI_API_KEY>"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "imagen3": {
            "command": "C:\\bin\\imagen3-mcp.exe",
            "env": {
                "GEMINI_API_KEY": "<GEMINI_API_KEY>"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "imagen3": {
            "command": "C:\\bin\\imagen3-mcp.exe",
            "env": {
                "GEMINI_API_KEY": "<GEMINI_API_KEY>"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
