MCP server for image generation using multiple providers (Google Gemini, OpenAI, BFL FLUX)
MCP Imagenate MCP server exists for a simple reason — assistants are far more useful when they can act on MCP Imagenate directly instead of describing what you should do. MCP server for image generation using multiple providers (Google Gemini, OpenAI, BFL FLUX).
The server ships on npm as mcp-imagenate, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once MCP Imagenate is connected, these are the calls the assistant has available:
nano-banana-2 — gemini-3.1-flash-image-previewnano-banana-pro — gemini-3-pro-image-previewgpt-image-2 — gpt-image-2flux-2-klein — klein-4bflux-2-pro — pro-previewflux-2-max — maxreve-image — latestVariable — RequiredGEMINI_API_KEY — *NANO_BANANA_API_KEY — *OPENAI_API_KEY — *GPT_IMAGE_API_KEY — *You will need 8 environment variables: GEMINI_API_KEY, NANO_BANANA_OUTPUT_DIR, NANO_BANANA_API_KEY, OPENAI_API_KEY, GPT_IMAGE_API_KEY, BFL_API_KEY, REVE_API_KEY, REVE_API_TOKEN. 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.
This sits in the AI and media services group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Imagenate's toolset — nano-banana-2, nano-banana-pro, gpt-image-2 and 11 more — is a fair guide to whether it matches your workflow. It is maintained by mimo-3; worth a glance at recent repository activity before you build anything load-bearing on it.
