Nanobanana MCP Server

A production-ready Model Context Protocol (MCP) server that provides AI-powered image generation capabilities through Google's Gemini models with intelligent model selection. It runs locally over stdio via the published package.

People who work with Gemini and Nanobanana and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Nanobanana MCP Server

before you install - you'll need

Set GEMINI_API_KEY, NANOBANANA_AUTH_METHOD, GCP_PROJECT_ID, GEMINI_BASE_URL, LOG_LEVEL, LOG_FORMAT before connecting. GCP_REGION, NANOBANANA_MODEL, IMAGE_OUTPUT_DIR are optional or environment-specific per the README.

Claude Code

claude mcp add zhongweili-nanobanana-mcp-server -- uvx nanobanana-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "zhongweili-nanobanana-mcp-server": {
      "command": "uvx",
      "args": [
        "nanobanana-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
