MCP server for Google Gemini 2.5 Flash Image preview (text-to-image, editing, composition)
MCP server for Google Gemini 2.5 Flash Image preview (text-to-image, editing, composition). The gemini nanobanana mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it rather than through you.
A beginner-friendly Model Context Protocol (MCP) server that brings Google's Gemini 2.5 Flash Image generation directly into your Claude conversations.
Installation goes through your MCP client rather than a global install: point it at gemini-nanobanana-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
You will need 5 environment variables: GEMINI_API_KEY, AUTO_SAVE, DEFAULT_SAVE_DIR, LOG_LEVEL, YOUR_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by Junhan2; worth a glance at recent repository activity before you build anything load-bearing on it.
