rog0x/mcp-image-tools

Provides five tools for working with images without downloading or processing them. You get metadata extraction via HTTP headers, favicon discovery across multiple sources (HTML links, manifest.json, and fallback routes), Open Graph and Twitter card image extraction for link previews, placeholder generation through the placehold.co API with customizable dimensions and colors, and responsive image markup generation with srcset and picture elements. Useful when you need to inspect what images a site uses, grab icons and preview images for card layouts, or generate boilerplate HTML for responsive designs. Metadata only, so it's fast and doesn't touch image data itself.
