Claude Code: ask. ### `ai_crawler_audit` - 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: ```untrusted-server-text 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` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text AI Visibility / GEO audit. Asks a panel of AI models a buyer-intent question ('what's the best ?') 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` - 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: ```untrusted-server-text 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` - 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: ```untrusted-server-text 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. ``` ### `flag_toxic_links` - The name "flag_toxic_links" says "link": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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` - The name "indexnow_submit" says "submit": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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:///.txt — this tool does not create that key for you. ``` ### `verify_link_live` - The name "verify_link_live" says "link": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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). ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `core_web_vitals` - The description's first verb is "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The description's first verb is "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "find_link_prospects" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `schema_validate` - The name "schema_validate" says "validate": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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). ``` ### `site_audit` - The description's first verb is "fetch": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The description's first verb is "return": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `backlinkmcp`: ```json { "permissions": { "allow": [ "mcp__backlinkmcp__domain_authority_score", "mcp__backlinkmcp__top_linkers_for_domain", "mcp__backlinkmcp__find_link_prospects", "mcp__backlinkmcp__site_audit", "mcp__backlinkmcp__schema_validate", "mcp__backlinkmcp__core_web_vitals" ], "ask": [ "mcp__backlinkmcp__backlinks_for_domain", "mcp__backlinkmcp__verify_link_live", "mcp__backlinkmcp__flag_toxic_links", "mcp__backlinkmcp__common_linkers", "mcp__backlinkmcp__ai_visibility_report", "mcp__backlinkmcp__ai_crawler_audit", "mcp__backlinkmcp__indexnow_submit" ], "deny": [] } } ```
