theluckystrike MCP Backlink Checker

An MCP server that allows agents to verify if a specific page links to a target domain, identifying link attributes such as dofollow/nofollow status, anchor text, HTTP status codes, and robots meta tags. It supports single page checks, batch audits, and brand mention detection without storing any data.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Backlink verification for SEO and link outreach. It covers whether a referring page links to a target domain, with dofollow or nofollow status and anchor text, audits of backlink lists, a page's outbound links, a referring domain's status including unlinked brand mentions, which outreach sites added a promised link, and noindex and nofollow robots signals. Pages are fetched live from the public web by McpStamp's hosted service. The free tier audits 3 URLs per request. One lifetime key unlocks this server and all 58 others: https://mcp.zovo.one/buy/bundle?src=instr.backlink-checker

Advertised by the server during the last successful anonymous check.
