ai_crawler_audit
AI crawler access audit
Audit which AI crawlers a site allows or blocks in robots.txt — sorted by CONSEQUENCE: blocking a VISIBILITY crawler (OAI-SearchBot, PerplexityBot, ChatGPT-User, Claude-User…) removes the site from live AI answers, while blocking a TRAINING crawler (GPTBot, CCBot, Google-Extended…) only opts out of model training. Those need opposite decisions. Checks 25 known AI crawlers + whether /llms.txt exists, plus general robots.txt hygiene (Sitemap directives, whole-site Disallow foot-guns). Free (no LLM calls).

ai_visibility_report
AI visibility report (Pro, spends credits)
AI Visibility / GEO audit. Asks a panel of AI models a buyer-intent question ('what's the best <category>?') and reports whether YOUR brand gets recommended, who the models prefer instead (share-of-voice across the panel), WHY the leader wins — diagnosed against BacklinkMCP's own authority/link data (referring-domain gap) — and which domains to earn links from to catch up. Two modes: `parametric` (default — the models' baked-in brand memory) or `retrieval` (live web-search models = what the AI answers right now, SEO-driven). **Pro plan only** (runs a live multi-model AI panel): 8 models × 3 prompts × up to 4 competitors per report.

backlinks_for_domain
Backlink profile
Full backlink payload for a domain: total inlink count plus the ranked list of linking domains (authority + outbound link count per linker). Returns up to 100 rows on Pro, 25 on the free tier; use domain_authority_score for just the headline number.

common_linkers
Common linkers across domains
Multi-domain backlink overlap: given 2-4 domains, returns the domains that link to MORE THAN ONE of them, ranked by overlap (how many of the set they link) then authority. Answers 'who links my whole niche?' — the must-have publications, directories, and roundups your competitors all share. Domain-level only (no per-link URL/anchor). Free compares 2 domains, Pro up to 4; returns up to 25 rows free / 100 Pro.

core_web_vitals
Core Web Vitals
Get Core Web Vitals (LCP, INP, CLS) and a performance score for a page via Google PageSpeed Insights — both a lab Lighthouse run and real-user CrUX field data when available.

domain_authority_score
Domain authority score
Get an editorial-authority score for a domain (weighted toward high-trust wiki/edu/gov/news referrers, from BacklinkMCP's proprietary web-scale link index). Returns a domain_rating-style score plus referring domain count.

find_link_prospects
Competitor link gap
Competitor backlink-gap analysis for link building. Given YOUR domain (the `domain` arg) and 1-3 competitor domains, returns domains that link to the competitor(s) but NOT to you, ranked by the linking domain's authority — a warm outreach shortlist (aka competitor gap). Domain-level only: the index has no per-link URLs or anchor text, so each row is a DOMAIN worth pitching for a link, not a confirmed link or a specific page. CDN/analytics/marketing-widget/social noise is filtered out. Free mines 1 competitor and returns up to 25 prospects; Pro mines up to 3 competitors and returns up to 100.

Free tier uses only the first."}}}
flag_toxic_links
Toxic backlink review queue
Toxic / low-quality backlink audit: scans a domain's LINKERS and flags spammy disavow CANDIDATES — abused TLDs (.tk/.xyz/.loan…), spam keywords in the domain, hyphen/keyword stuffing, and link-farm-level outbound counts. The inverse of find_link_prospects. Domain-level heuristic only (no per-link URL/anchor), so each row is a DOMAIN worth REVIEWING, never a confirmed toxic link. Note: Google says most sites should NOT disavow — use this to audit, not to auto-disavow. Free returns up to 25 flags, Pro up to 100.

indexnow_submit
Submit URLs to IndexNow
Submit one or more URLs to IndexNow for near-instant indexing by Bing and Yandex. Requires an IndexNow key that YOU control and have already hosted at https://<your-domain>/<key>.txt — this tool does not create that key for you.

schema_validate

site_audit
On-page SEO audit
Fetch a page and audit core on-page SEO signals: title/meta description length, canonical tag, heading structure, image alt text coverage, viewport tag, robots meta, word count. Returns a list of concrete issues found. Single page only — not a site crawl.

top_linkers_for_domain
Top linking domains
Return the top 25 domains linking to a given domain, ranked by the linking domain's own authority, with link counts. Good for a quick competitive/backlink-profile skim.

verify_link_live
Verify backlinks live
Live-verify backlinks: fetches linking domains' homepages RIGHT NOW and confirms an actual href to the target domain exists on each. Complements the index with real-time proof. Only homepages are fetched, so 'not_found' means 'no link on the homepage today', not 'the link is gone'. Checks the top 8 linkers by default (max 15).
