Description

Prompt-to-Image Generator & WordPress Uploader (n8n Workflow)

This workflow generates high-quality AI images from text prompts using Leonardo AI, then automatically uploads the result to your WordPress media library and returns the final image URL.

It functions as a Modular Content Production (MCP) tool - ideal for AI agents or workflows that need to dynamically generate and store visual assets on-demand.

⚙️ Features

• 🧠 AI-Powered Generation
  Uses Leonardo AI to create 1472x832px images from any text prompt, with enhanced contrast and style UUID preset.

• ☁️ WordPress Media Upload
  Uploads the image as an attachment to your connected WordPress site via REST API.

• ☁️ Twitter Media Upload
  Uploads the image to twitter so that you can post the image later on to X.com using the media_id

• 🔗 Returns Final URL
  Outputs the publicly accessible image URL for immediate use in websites, blogs, or social media posts.

• 🔁 Workflow-Callable (MCP Compatible)
  Can be executed standalone or triggered by another workflow. Acts as an image-generation microservice for larger automation pipelines.
