Midjourney API and MCP: how to add image generation to your project

Midjourney is an image generation model. NeuralSpace offers the following models: Midjourney v7. 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. Below are the model capabilities, request examples and setup steps.

What Midjourney can do

Midjourney v7 generates images from text, priced by generation mode: relaxed, fast or turbo. The model is known for its artistic style and suits concept art, illustrations and creative tasks.

API endpoint

Send a request to POST /v1/images/generations. Example: {"model": "midjourney", "prompt": "a fantasy landscape", "mode": "fast"}. Authorization uses an API key in the x-api-key header. Available model ids: midjourney.

MCP tools

The NeuralSpace MCP server is available at POST /mcp (Streamable HTTP). To work with Midjourney, 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.
