Claude.ai backlink checker referring_domain_summary

How to: Claude.ai backlink checker referring_domain_summary

client:Claude.ai transport:streamable-http tool:referring_domain_summary

Add backlink checker to Claude.ai

  1. 01

    Open Settings → Connectors → Add custom connector and merge this in. Keep any servers already there.

https://mcp.zovo.one/mcp/backlink-checker
  1. 02

    Save the file and restart Claude.ai.

  2. 03

    Ask for something referring_domain_summary does. Claude.ai lists the server's tools on connect and calls referring_domain_summary itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that backlink checker's identifier in your config matches the one above exactly.

Claude on the web takes a remote URL and completes OAuth in the browser. For a packaged server use Claude Desktop or Claude Code instead. Claude.ai docs

Set these first

backlink checker will not start until these are set, so referring_domain_summary never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
