Imagedimensions tools (1)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • scan_image_dimensions

    Audit the images on any public web page. Returns each image's natural vs rendered dimensions, flags oversized images (downloaded much larger than displayed — a common Largest Contentful Paint problem), and breaks down formats (WebP/AVIF adoption). Useful for web performance and image-optimization work.

What its tools let an agent do: 1 read

Install Imagedimensions in Claude Code, Cursor or VS Code

Runs npx -y imagedimensions-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Imagedimensions repository's README, as published. We do not edit it. Read it on GitHub

imagedimensions-mcp

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.

Install / run

// Claude Desktop / any MCP client config
{
  "mcpServers": {
    "imagedimensions": {
      "command": "npx",
      "args": ["-y", "imagedimensions-mcp"]
    }
  }
}

Tool

scanimagedimensions

Returns a text report plus structured content:

  • total / visible image counts and CSS-background count
  • modern-format share (WebP + AVIF)
  • format breakdown
  • the list of oversized images (natural → rendered, overshoot ratio, format, src)
  • a link to the full visual report on imagedimensions.com

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?"

Why "oversized" matters

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.
