How do I get a Midjourney API key?

Sign up at [Ace Data Cloud](https://acedata.cloud/) and subscribe to the Midjourney Imagine API service. You'll receive an API key that works with this MCP server.

What's the difference between upscale and variation?

Upscale increases resolution of a specific grid image (1-4) to full quality. Variation creates 4 new creative alternatives based on that image's style and composition. Use upscale for final output, variation for exploration.

How long does image generation take?

Typically 30-60 seconds. Use get_task_status to check progress. The API returns a task ID immediately, and you can poll for completion or set a callback URL for async notification.

About Midjourney MCP Server

Connect Midjourney image generation to any AI agent and create stunning visuals through natural conversation. Generate images from text prompts, upscale to high resolution, create variations, blend images, and even reverse-engineer prompts from existing images.

The OpenAI Agents SDK auto-discovers all 9 tools from Midjourney through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns — chain multiple agents where one queries Midjourney, another analyzes results, and a third generates reports, all orchestrated through the Vinkius.

What you can do

Text-to-Image — Generate high-quality images from descriptive prompts
Upscale — Enhance any of the 4 grid images to full resolution
Variations — Explore creative alternatives based on any generated image
Blend — Combine 2-5 images into a new composition
Describe — Reverse-engineer a prompt from any image
Inpaint — Edit specific regions of images with masks
Task Monitoring — Track generation progress and retrieve completed images

The Midjourney MCP Server exposes 9 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use OpenAI Agents SDK with the Midjourney MCP Server

OpenAI Agents SDK provides unique advantages when paired with Midjourney through the Model Context Protocol.

Native MCP integration via `MCPServerSse` — pass the URL and the SDK auto-discovers all tools with full type safety

Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

Midjourney + OpenAI Agents SDK Use Cases

Practical scenarios where OpenAI Agents SDK combined with the Midjourney MCP Server delivers measurable value.

Automated workflows: build agents that query Midjourney, process the data, and trigger follow-up actions autonomously

Multi-agent orchestration: create specialist agents — one queries Midjourney, another analyzes results, a third generates reports

Data enrichment pipelines: stream data through Midjourney tools and transform it with OpenAI models in a single async loop

Customer support bots: agents query Midjourney to resolve tickets, look up records, and update statuses without human intervention

Midjourney MCP Tools for OpenAI Agents SDK (9)

These 9 tools become available when you connect Midjourney to OpenAI Agents SDK via MCP:

blend

Provide URLs of existing images to blend together. Optionally add a text prompt to guide the blend. Blend multiple images together into one composition

describe

Useful for understanding how to recreate styles and compositions. Generate a text prompt from an image (reverse engineer)

get_task_status

Returns progress percentage, image URLs when ready, and available actions (upscale/variation). Check the status of an image generation task

get_tasks

Useful for monitoring ongoing generations and finding image IDs for upscale/variation. List recent image generation tasks

imagine

The prompt should be in English and can include style modifiers like "--ar 16:9" for aspect ratio, "--v 6" for version, "--s" for stylization. Returns a task ID and thumbnail URL. Use the task ID to check generation progress. Generate an image from text prompt using Midjourney

inpaint

The rest of the image remains unchanged. Edit a specific region of a generated image using a mask

reroll

Useful when none of the initial 4 images are satisfactory. Regenerate 4 new images with the same prompt

upscale

Returns the upscaled image URL. Upscale one of the 4 generated images to higher resolution

variation

Useful for exploring different interpretations of a concept. Create a variation of one of the 4 generated images

Example Prompts for Midjourney in OpenAI Agents SDK

Ready-to-use prompts you can give your OpenAI Agents SDK agent to start working with Midjourney immediately.

"Upscale image position 2 from the last generation."

"Describe this image and tell me what prompt would create it: https://example.com/art.jpg"
