Backlink profile summary

You are wiring up the superagnt "SEO" API to use this endpoint: Backlink profile summary.

1. CONNECT over MCP (preferred). No token to paste either way.
   On Claude (claude.ai, the desktop app, or Claude Code signed in with a Claude
   account), the server is a connector: give the user this link, they click Add
   and approve:
     https://claude.ai/customize/connectors/yours?modal=add-custom-connector&connectorName=superagnt&connectorUrl=https%3A%2F%2Fmcp.superagnt.com%2Fmcp&open_in_browser=1
   Any other MCP client (or Claude Code signed in with an API key): add the server
   and let the client run the browser sign-in:
     claude mcp add --scope user --transport http superagnt https://mcp.superagnt.com/mcp
     claude mcp login superagnt
   MCP endpoint: https://mcp.superagnt.com/mcp
   After connecting, the tool you want is named exactly:
     data_seo_backlinks_summary
   Call agnt_tools_search or agnt_tools_list_enabled to confirm it is available.

2. REST fallback (if you are not using MCP):
     POST https://api.superagnt.com/backlinks-summary
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - target (string, required) — Domain, subdomain or full page URL. Domains without protocol; pages with protocol.
   Optional parameters:
    - include_subdomains (boolean, optional) — Count links to subdomains too. Default true.
    - exclude_internal_backlinks (boolean, optional) — Ignore links from the target to itself. Default true.

3. COST & KEY. This endpoint is metered — pricing varies by request, from $0.05 per call. Only successful calls are charged.

4. TEST. Connect the server (or set the key), discover the tool
   (data_seo_backlinks_summary), run one minimal call with just the required parameters,
   and report back the shape of the JSON response (top-level fields).

  "name": "backlinks_summary",
  "description": "Returns a domain or page's backlink profile at a glance: total backlinks, referring domains, domain rank, spam score, broken links, and anchor/TLD distributions (flat object at result[0], no items array). The `rank` here is the target domain's own backlink-authority rank — a different metric from the per-referring-domain `rank` in backlink_gap/referring_domains rows, so the same domain can carry different numbers in each. Use it to qualify a site's authority in one cheap call before deeper link analysis.",
