Automate Blog Hero Images with AI Agents
Use intent-aware tools like generate_article_hero_image to automatically create properly-sized hero images for your blog posts. Build a complete content pipeline.
The Intent-Aware Image Tool
MCP Media Engine provides generate_article_hero_image, a tool designed specifically for content workflows. Pass it a title and summary, and it outputs the right aspect ratio automatically.
Why This Matters
Manual hero image selection breaks automation. With intent-aware generation: - No guessing aspect ratios — the tool handles it - Consistency across hundreds of posts - Natural language prompting (no API tinkering)
Building Your Pipeline
Example: Content Agent with Auto-Imagery
async function publishBlogPost(article: {
title: string;
summary: string;
content: string;
}) {
// Agent generates the content
const heroImage = await mcp.generateArticleHeroImage({
title: article.title,
summary: article.summary
});// Save to CMS await cms.create({ title: article.title, content: article.content, heroImageUrl: heroImage.url, heroAspectRatio: heroImage.aspectRatio }); } ```
Workflow Examples
Static Blog Site 1. AI agent writes post 2. Tool generates hero image (stored in R2 or S3) 3. Hugo/Next.js deploys automatically
CMS Integration 1. Webhook triggers on new post 2. Agent reads post metadata 3. Hero image auto-inserted 4. Publish without manual review
Social Media Pipeline 1. Blog publishes 2. Agent extracts title and summary 3. Generate platform-specific crops (1:1 for Instagram, 16:9 for LinkedIn) 4. Schedule posts automatically
Best Practices
- **Give context** — Longer summaries produce better images
- **Use descriptive titles** — More specific = better results
- **Retry failed generations** — Rarely a tool can't generate; try again
- **Cache results** — Store generated URLs to avoid re-generating
Pricing
Each generation costs ~7¢ and takes ~15 seconds. For a 50-post blog launch, expect ~$3.50 and ~12 minutes total.
