Check backlinks from a chat: does a page link to your domain, dofollow or nofollow, anchor text and robots guards. You give it referring page URLs and a target domain. link_check fetches one page and reports whether it links to the domain, dofollow or nofollow, the anchor text, HTTP status and page-level robots guards (meta robots and X-Robots-Tag noindex/nofollow). link_audit runs the same check across a list of URLs and returns one table row per link found. robots_guard_check reports just the robots signals on a URL without extracting links. The server makes one outbound GET per URL and stores nothing.
Every tool here is a server-side GET against a URL you name, which is exactly what a browser connector wants: the fetched page never touches your disk, and the verdict table comes back in the answer itself.
| You say | Tool |
|---|---|
| Check whether https://example.com/blog/roundup links to mydomain.com and if it is dofollow. | link_check |
| Audit these 20 guest-post pages against mydomain.com. | link_audit |
| Is that link page even indexable, or is it noindexed? | robots_guard_check |
The suite is 8 tests, 8 passing, 0 failing (node --test), covering link extraction and classification, rel-splitting, page-level robots guards and the Pro gate on batch size. The smoke and license-gate tests sit alongside it.
https://mcp.zovo.one/mcp/connect mints an anonymous token and prints a URL per server, including this one, shaped like https://mcp.zovo.one/mcp/backlink-checker/t/<token>. That URL works with no headers: the token is in the path, not in an Authorization field this form does not have.
Idle anonymous tokens are swept after 30 days. Since this route has no filesystem, a file MCP Backlink Checker generates comes back as a download link that expires after one hour. A Pro key can replace the token in the same URL and removes the free-tier limits.
On an individual Pro or Max plan you add the connector yourself from Customize, Connectors. On Team and Enterprise it is the other way round: only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, and members then connect to what the Owner added rather than pasting their own URL.
Free: link_check and robots_guard_check are free and unlimited; link_audit covers up to 3 URLs per call on the free tier. Reads are free on every tier. Pro is $19 once, verified offline, and binds to the token after checkout.
No. Add custom connector offers an Advanced settings section with an OAuth Client ID and Client Secret, but the connect-by-URL route does not use it. Leave both blank: the token in the URL path is what authenticates.
That is documented, not a bug: on Team and Enterprise, only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, Add, Custom, Web. After that, members connect to the URL the Owner added from Customize, Connectors.
Yes. The token segment of the URL from /mcp/connect can be replaced with a Pro key, which removes the free-tier limits on MCP Backlink Checker for that connector.
The connector runs server-side with no filesystem of its own, so any file MCP Backlink Checker produces is handed back as a download link that expires after one hour, rather than a path on disk.
