The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Imagedimensions MCP listing page.
An MCP server that audits the images on any public web page — natural vs. rendered dimensions, oversized-image detection, and format breakdown — so AI agents (Claude, Cursor, Windsurf, etc.) can check image performance during development.
Powered by imagedimensions.com. The scan runs server-side, so no local browser or Chrome install is required.
scan_image_dimensions| Param | Type | Description |
|---|---|---|
url | string (required) | Public URL of the page to audit. |
oversizedThreshold | number (optional) | Area-overshoot ratio to flag as oversized. Default 4 (≈2× per dimension). |
Returns a text report plus structured content:
Example agent uses: "Audit the images on https://example.com," "Which images on this page are oversized and hurting LCP?", "What % of this site's images use modern formats?"
An image downloaded much larger than the box it renders into wastes bandwidth and slows Largest Contentful Paint — the most common image-performance mistake on the web. See the writeup.
