FLUX.2 joins Claude, Cursor, and Codex via an official MCP server.

Black Forest Labs releases an official MCP server for FLUX, letting Claude, Cursor, and Codex users generate images via OAuth without API keys or coding.

Black Forest Labs releases an official MCP server for FLUX, which makes its image models directly accessible from clients compatible with the Model Context Protocol: Claude, Cursor, Codex, Windsurf, Hermes. Users no longer have to handle API keys or write code: connection is made via OAuth, and the agent automatically routes the request to the most suitable FLUX variant.

Five models are accessible: FLUX.2 Pro Preview by default, FLUX.2 Max for maximum quality, two Klein variants (9B Preview and 4B) optimized for speed, and FLUX.2 Flex for compositions with a strong typographic component. The server exposes four tools: `generateimage` (up to eight images in parallel, covering text-to-image, editing, multi-reference composition, style transfer, inpainting, and outpainting), `generatevariations` (variations from a previous generation), `gethistory` (history lookup), and `getcredits` (remaining balance).

The official demonstration illustrates an advertising use case: the user requests four concepts for a kombucha brand, the agent switches to Klein to produce sketches, then to Pro to refine a coffee visual, and then to Max for the final render, without manual intervention in model selection.

Billing is managed directly by Black Forest Labs, on the account of the organization selected during OAuth authentication. The server can be reached at `mcp.bfl.ai`. A local variant based on `mcp-remote` is offered for clients that do not natively handle OAuth.
