## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-24.

- **Endpoint Security**: 66/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 11 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2311 tokens (~177/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 97/100
  - Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (13)

### `domain_authority_score` (~74 tokens)

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.

Input parameters:

- `domain` (string, required): Root domain, e.g. 'stripe.com'.

### `top_linkers_for_domain` (~62 tokens)

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.

Input parameters:

- `domain` (string, required): Root domain, e.g. 'stripe.com'.

### `backlinks_for_domain` (~79 tokens)

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.

Input parameters:

- `domain` (string, required): Root domain, e.g. 'stripe.com'.

### `verify_link_live` (~166 tokens)

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).

Input parameters:

- `domain` (string, required): Root domain whose backlinks to verify, e.g. 'stripe.com'.
- `limit` (integer): Optional: how many top linkers to check when 'linkers' is omitted (default 8, max 15).
- `linkers` (array): Optional: specific linking domains to check (max 15). Defaults to the top linkers from the graph.

### `find_link_prospects` (~212 tokens)

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.

Input parameters:

- `competitors` (array, required): Competitor root domains to mine for gap prospects (1-3), e.g. ['rival1.com','rival2.com']. Free tier uses only the first.
- `domain` (string, required): YOUR root domain — the site you want more backlinks for, e.g. 'yoursite.com'.

### `flag_toxic_links` (~172 tokens)

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.

Input parameters:

- `domain` (string, required): The domain whose inbound links you want to audit for toxic/spam linkers, e.g. 'yoursite.com'.

### `common_linkers` (~144 tokens)

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.

Input parameters:

- `domains` (array, required): Root domains to intersect (2-4), e.g. ['a.com','b.com','c.com']. Free tier uses only the first 2.

### `ai_visibility_report` (~604 tokens)

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.

Input parameters:

- `category` (string): Optional shortcut used only if `prompts` is omitted — turned into one prompt 'What is the best <category>?', e.g. 'CRM for small business'.
- `competitors` (array): Competitor root domains to track share-of-voice against and diagnose the winner, e.g. ['rival1.com','rival2.com']. Supplying the winner as a domain unlocks the link-gap diagnosis.
- `depth` (string): 'draft' = cheap iteration pass (2 models × 1 prompt) for trying prompts/competitors. 'full' (default) = the whole panel. Draft costs 1 credit (2 for retrieval).
- `domain` (string, required): YOUR root domain — the brand you're measuring AI visibility for, e.g. 'yoursite.com'.
- `facts` (array): Optional ground-truth facts about YOUR product (max 5), e.g. ['pricing starts at $29/mo','has a free tier']. When supplied, the panel is also asked what it knows about your brand and each fact is ver…
- `history` (boolean): true = return the permanent archive of past runs for this domain (mention rate, rank, leader over time) instead of running a new panel. Costs no credits. Optionally combine with `mode` to filter para…
- `mode` (string): 'parametric' (default) = the models' baked-in brand memory (cheap). 'retrieval' = live web-search models (what the AI answers now, SEO-driven; costs more credits).
- `prompts` (array): Buyer-intent queries to ask the panel, e.g. ['best project management tool for a startup'].
- `samples` (integer): Repeat draws per (prompt×model) cell (default 1, max 10). Answer engines are nondeterministic — more samples tighten the 95% confidence interval on your rates. Use samples>=5 for a defensible inclusi…

### `ai_crawler_audit` (~154 tokens)

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).

Input parameters:

- `domain` (string, required): Root domain to audit, e.g. 'yoursite.com'.

### `site_audit` (~81 tokens)

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.

Input parameters:

- `url` (string, required): Full page URL, e.g. https://example.com/page

### `schema_validate` (~69 tokens)

Structured data check

Extract and validate JSON-LD structured data (schema.org) from a page. Checks JSON validity and flags missing recommended fields for common types (Article, Product, Organization, WebSite, BreadcrumbList, FAQPage, LocalBusiness).

Input parameters:

- `url` (string, required): Full page URL to check for structured data.

### `core_web_vitals` (~80 tokens)

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.

Input parameters:

- `strategy` (string): Test as mobile or desktop. Default 'mobile'.
- `url` (string, required): Full page URL to test.

### `indexnow_submit` (~102 tokens)

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.

Input parameters:

- `key` (string, required): Your IndexNow key, already hosted at https://<host>/<key>.txt
- `urls` (required): One URL or an array of URLs, all on the same host.
