Security Report

5.8
Moderate5.8Moderate Risk

This is a well-structured MCP server for querying the seo-backlinks.net API. Authentication is properly enforced via environment variable (SEO_BACKLINKS_API_KEY), input validation is present, and the codebase has no injection vulnerabilities or malicious patterns. Minor code quality issues (broad exception handling, no sensitive data logging safeguards) and a default demo API key in code prevent a higher score, but these are low-severity concerns appropriate for this category and use case. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

seo-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"
  • "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.
