Findings

Matches of fixed checks, with the text they matched.

2 warn
  • Warnverify_link_live

    The server marks "verify_link_live" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "verify_link_live" says "link": a word for a change.

  • ai_crawler_auditAudit 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…) remo…No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    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).

    Annotations the server declares

    • title: AI crawler access audit

    • readOnlyHint: true
  • ai_visibility_reportAI Visibility / GEO audit.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • openWorldHint: true
    • readOnlyHint: false
    • destructiveHint: false

  • common_linkersMulti-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.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    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.

    • title: Common linkers across domains

  • indexnow_submitSubmit one or more URLs to IndexNow for near-instant indexing by Bing and Yandex.No findings

    Why it is in this group

    • The name "indexnow_submit" says "submit": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    Description, as the server wrote it

    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
