mcp -nano-banana

This MCP server exposes Nanana AI's nano banana image generation capabilities to MCP clients (such as Claude Desktop). It supports two core tools: text_to_image for generating images from prompts, and image_to_image for transforming existing images based on a prompt. To use it, configure your MCP client to point at this server (for Claude Desktop, add an entry under mcpServers with a name like nanana, set the command to npx and the args to -y @nanana-ai/mcp-server-nano-banana, and provide your NANANA_API_TOKEN). Once running, you can request image generation by providing a text prompt to text_to_image, or supply image URLs plus a transformation prompt to image_to_image. The server uses Nanana API tokens for authentication and can optionally target a custom API URL via NANANA_API_URL if you need to point to a different endpoint.

Prerequisites:

• Node.js and npm installed on your machine
• Access to the Nanana API with a generated API token

Install globally with npm:

npm install -g @nanana-ai/mcp-server-nano-banana

Configure Claude Desktop (or your MCP client) to use the server:

1. Create or edit your Claude Desktop MCP config (example path shown in README):

{
  "mcpServers": {
    "nanana": {
      "command": "npx",
      "args": ["-y", "@nanana-ai/mcp-server-nano-banana"],
      "env": {
        "NANANA_API_TOKEN": "your-api-token-here"
      }
    }
  }
}

2. Save the config and restart the client to load the MCP server.

Alternative local test (without global install): you can also run the server via npx directly in a project context:

npx -y @nanana-ai/mcp-server-nano-banana

Environment variables:

• NANANA_API_TOKEN: Your Nanana AI API token (required)
• NANANA_API_URL: Optional custom API URL (defaults to https://nanana.app)

Build/test tips:

• After starting, you can verify the server responds to MCP requests from your client.
• Ensure your API token has the necessary permissions for image generation.

Tips and common notes:

• Ensure NANANA_API_TOKEN is kept secure and not checked into source control.
• If you encounter authentication errors, re-check token validity in your Nanana account and token permissions.
• NANANA_API_URL can be useful for testing against a local or staging endpoint; omit it to use the default production URL.
• The MCP server expects mcpClients to send text_to_image and image_to_image requests with appropriate payloads as defined by the MCP protocol. Refer to the client documentation for exact request shapes.
• If you update the server version, you may need to refresh your client config in Claude Desktop to reload capabilities.
