Seo Backlinks

MCP server that lets Claude, Cursor, Windsurf, Cline, and other AI agents check backlinks, domain rating, and expired-domain drops directly via seo-backlinks.net.

Built on Common Crawl data — 4.3B backlinks indexed, 262M hosts ranked.

What it does

Ask Claude:

• "What's the Domain Rating of nytimes.com?"
• "Show me the top 10 sites linking to stripe.com"
• "List today's expired domains with backlinks under $50 potential"
• "Compare backlink profiles of ahrefs.com vs semrush.com"

Claude will use this MCP server to query the seo-backlinks API and give you the answer inline.
