What is the Mj MCP MCP server?

Mj mcp mcp server lets Claude, Cursor and other MCP clients work with Mj MCP directly. A MCP server implementation for generating images with Midjourney.

What Mj MCP does

A MCP server implementation for generating images with Midjourney.

Tools it exposes

Once connected, the assistant can call these 2 tools directly:

  • prompt — Description of the image you want to generate
  • aspect_ratio — Aspect ratio of the image (e.g. "16:9")

Installing the mj mcp mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Mj MCP sits in that group, and the shape of its toolset — prompt, aspect_ratio — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by Lala-0x3f.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mj mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

  • Use Mj MCP to aspect ratio.

Frequently asked questions

It connects Mj MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (prompt, aspect_ratio) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Mj MCP directly.
