generating_image
Generate an image from prompt (a description of the image you want) and aspect_ratio (e.g. "16:9"); returns a string.
LABSCO SUMMARY
One tool, session-token auth, version pinned in config.
The surface is deliberately minimal — prompt in, image out — and the suffix setting is the detail that saves repetition, since the model version rides along with every request automatically. Weigh the auth model before installing: session tokens are more sensitive than a scoped API key, and there is no separate service account here.
What it is
A small MCP server that puts Midjourney image generation behind a single tool call. It authenticates with your own Midjourney session tokens rather than an API key, and appends a version suffix to every prompt so the model version is set once in configuration instead of repeated in each request.
What you get
- An image generated from a text description and an aspect ratio such as
16:9, returned as a string —generating_image - A default suffix appended to every prompt,
--v 6.1unless you overrideSUFFIX, so the model version is a configuration decision - An overridable endpoint through
API_BASE, which defaults tomidjourney.com
Requirements
Your own Midjourney authentication, supplied as the two session tokens TOKEN_R and TOKEN_I — not an issued API key, which means the credential is tied to your logged-in session and generation bills to your Midjourney plan. API_BASE and SUFFIX are optional. Run it with uvx midjourney-mcp over stdio. The project is licensed GPL-3.0, which is stricter than most servers in this category and matters if you plan to embed it.
Setup effort
One command plus a key — uvx midjourney-mcp, then supply credentials
USE CASES
01
Generating an image inside a longer piece of work
Have the assistant call for the image with the aspect ratio the layout needs, instead of switching to Discord and back.
02
Keeping the model version consistent
Set the suffix once in configuration so every prompt goes out on the same version, rather than remembering to append it.
