Details
From the project READMEseo-backlinks MCP Server
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"

- "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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
