Backlink data your
agent can actually query.
An MCP server + REST API for domain authority and backlink graphs — built so any coding agent, chatbot, or script can call it directly. No dashboard required.
Powered by a proprietary web-scale link graph with editorial-authority scoring — the signal that high-trust wiki, edu, gov and news links carry, resistant to link-farm inflation, at a fraction of enterprise-crawler prices.
"domain": "stripe.com",
"found": true,
"domain_rating": 80.9,
"referring_domains": 702082,
"top_linkers": [
{"source": "googleapis.com", "links_out": 2570},
{"source": "cloudflare.com", "links_out": 4755}
]
}
The backlink layer your agent is missing.
One graph. Four ways in — score a domain, rank its linkers, list the top ranked referring domains, or wire it straight into your agent's tool loop.
Editorial-authority scoring, not link-farm counting.
Weighted toward wiki, edu, gov, and news links — the signal that's expensive to fake and cheap to trust.
- Domain rating + referring-domain count
- Wiki / edu / gov / news-weighted
- Farm-resistant by construction
Ranked by the authority of who's linking.
Not just a count of inlinks — a ranked view of which sources actually carry weight.
- Ranked by linker authority
- Outbound-link counts per source
- Live link verification via verify_link_live
Total inlinks, plus the top 100 that matter.
A ranked slice of referring domains around a target — 25 on Free, 100 on Pro — not a dump of every row in the index.
- Total inlink counts
- Up to 100 ranked linking domains on Pro (25 free)
- 7-day cached results for speed
One URL for agents, one for scripts.

Straight answers.
What is BacklinkMCP?
A remote MCP server and REST API for domain authority and referring-domain graphs. Built so an agent can query the index — not a dashboard you sit in.
Is this per-link URL and anchor data?
No. The index is domain-level: referring domain, authority, outbound count. No per-link URL, anchor text, or rel/dofollow fields.
Does flag_toxic_links mean I should disavow?
No. It is a heuristic review queue on the low-authority tail, not proof a domain is toxic and not an automatic disavow list.
MCP or REST?
MCP when the client is an agent (Claude, Cursor). REST when you own the HTTP client (scripts, cron, n8n). Same engine both ways. Details on the MCP vs REST article.
What does free vs Pro include?
Free: 10 lookups/day per IP, 25 backlink rows, no signup. Pro $19/mo: unlimited daily lookups, 100 rows. Operator-issued today — self-serve checkout is not live. Pricing.
How do I install the MCP server?
Point your client at https://backlinkmcp.com/api/mcp. Step-by-step on docs.
Can ChatGPT or Claude check backlinks on their own?
No — without a tool they answer from training data and guess. We ran the same backlink question through three LLMs and none could look it up: can LLMs check backlinks? That test is why this MCP server exists.
Can I try it without installing anything?
Yes — the free backlink checker runs the same authority lookup in the browser, no signup.
