FLUX API and MCP: how to add image generation to your

FLUX is an image generation model. NeuralSpace offers the following models: FLUX 2 Pro. They all run through a single public API, and there is a ready MCP server for AI agents. The key is issued on the API keys page.

What FLUX can do

FLUX 2 Pro generates images from a text description with high quality and detail. It supports 1K and 2K resolutions. The model renders textures, light and composition well, suiting illustrations, concepts and ad materials.

API endpoint

Send a request to POST /v1/images/generations. Example: {"model": "flux-2-pro", "prompt": "a landscape at sunset", "resolution": "2K"}. Authorization uses an API key in the x-api-key header. Available model ids: flux-2-pro.

MCP tools

The NeuralSpace MCP server is available at POST /mcp (Streamable HTTP). To work with FLUX, an agent uses the tools: generate_image, list_models, get_balance. This lets Claude Code, Cursor and other MCP clients use the site models directly.

How to connect

Sign up on NeuralSpace, open the API keys page and create an nsk-… key. Then pass it in the request header or in your MCP client settings. Full documentation is on the the /v1/docs page.
