Connect in 2 minutes
Get your API key at https://cotlet.dev/app and export it as COTLET_API_KEY.
Claude Code
claude mcp add --transport http cotlet https://cotlet.dev/mcp/v1 --header "Authorization: Bearer $COTLET_API_KEY"
ChatGPT
Settings → Apps → add connector URL https://cotlet.dev/mcp/v1, then sign in with Cotlet.dev. No API key needed.
Cursor
Copy .cursor/mcp.json from this repo into your project:
{
"mcpServers": {
"cotlet": {
"url": "https://cotlet.dev/mcp/v1",
"headers": {
"Authorization": "Bearer ${COTLET_API_KEY}"
}
}
}
}
Run it locally (stdio)
This repo is a real MCP server. It speaks MCP over stdio, lists its Midjourney tools without any key, and forwards every tool call to the hosted Cotlet.dev server. The hosted URL above stays the recommended way. Use this when your client only starts local servers.
{"mcpServers":{"midjourney":{"command":"uvx","args":["midjourney-mcp"],"env":{"COTLET_API_KEY":"your-key"}}}}
Or with Docker:
docker build -t midjourney-mcp .
docker run -i --rm -e COTLET_API_KEY midjourney-mcp
Tools: midjourney_guide, midjourney_status, midjourney_open, midjourney_read, midjourney_click, midjourney_type, midjourney_close. Without COTLET_API_KEY a tool call answers: "Set COTLET_API_KEY. Get a key at https://cotlet.dev/app".
Command line
Python 3.10+, nothing else to install. From PyPI:
pip install midjourney-mcp # or run it once: uvx midjourney-mcp connect

Questions from Midjourney users
How do I connect Midjourney to ChatGPT or Claude?
Sign up at cotlet.dev, log in to Midjourney once in its Cloud Browser and add Cotlet to ChatGPT or Claude, following the steps in your console. No API key is needed. ChatGPT and Claude then work in your Midjourney account through Cotlet, in their phone apps too.
What can ChatGPT do in Midjourney?
With Cotlet, ChatGPT, Claude and other AI agents handle jobs like these in Midjourney: run a list of prompts; sort new creations into folders; turn your best images into videos. You ask in plain words, and anything that reaches other people waits for your OK first.
Can I use the Midjourney API without an AI agent?
Yes. Call Cotlet's REST API from a script or an HTTP step in n8n, Make or Zapier with your Cotlet key. MCP is the alternative for AI agents; you do not need to connect an agent to use REST.
How do I get access?
Create a free account at https://cotlet.dev, open Midjourney under Integrations in the console and log in to Midjourney in its Cloud Browser. The trial starts when you sign up, no card asked.
