MCP server that audits images on any web page — natural vs rendered dimensions, oversized-image detection, and format br
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.
IMAGEDIMENSIONS_API_BASE — override the API base (default https://imagedimensions.com).MIT
Run Claude Code as an MCP server so any agent can delegate coding tasks to it
