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.

Google ADK natively supports Midjourney as an MCP tool provider — declare the Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 9 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.

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 Google ADK 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 Google ADK with the Midjourney MCP Server

Google ADK provides unique advantages when paired with Midjourney through the Model Context Protocol.

Google ADK natively supports MCP tool servers — declare a tool provider and the framework handles discovery, validation, and execution

Built on Gemini models, ADK provides long-context reasoning ideal for complex multi-tool workflows with Midjourney

Production-ready features like session management, evaluation, and deployment come built-in — not bolted on

Seamless integration with Google Cloud services means you can combine Midjourney tools with BigQuery, Vertex AI, and Cloud Functions

Midjourney + Google ADK Use Cases

Practical scenarios where Google ADK combined with the Midjourney MCP Server delivers measurable value.

Enterprise data agents: ADK agents query Midjourney and cross-reference results with internal databases for comprehensive analysis

Multi-modal workflows: combine Midjourney tool responses with Gemini's vision and language capabilities in a single agent

Automated compliance checks: schedule ADK agents to query Midjourney regularly and flag policy violations or configuration drift

Internal tool platforms: build self-service agent platforms where teams connect their own MCP servers including Midjourney

Midjourney MCP Tools for Google ADK (9)

These 9 tools become available when you connect Midjourney to Google ADK 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 Google ADK

Ready-to-use prompts you can give your Google ADK agent to start working with Midjourney immediately.

Midjourney + Google ADK FAQ

Common questions about integrating Midjourney MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
