@corralimited/snapdiff-mcp
Standalone MCP server for SnapDiff. Exposes four tools to local agents:
- Compare two web pages visually — diff percentage plus a highlighted diff image
- Capture a screenshot of any URL
- Check whether a page changed vs. a previous capture
- Render HTML/CSS to an image (OG cards, social images, email headers)
Hits the public SnapDiff REST API. Bring your own API key.
