Every post on this blog needs two images that do completely different jobs: a social card that has to earn a click in a feed, and an inline hero that opens the article. This post is about how the blog makes both — a typographic default that costs nothing, an opt-in artificial-intelligence (AI) cover that costs about four cents, and the little Model Context Protocol (MCP) server that wires an image model straight into Claude Code. The cover above was made by that exact pipeline.
