Google Search Console (18)

Workhorses

• gsc_list_properties - properties the credentials can see, with permission level and a derived writable flag (true for siteOwner / siteFullUser).
• gsc_search_analytics - the workhorse: clicks/impressions/CTR/position by dimensions, date range, filters, and data_state.
• gsc_top_queries / gsc_top_pages - convenience top-N wrappers.
• gsc_compare_periods - current vs prior window with per-key deltas. v0.2.0 added sort_by, sort_dir, min_delta_clicks / _impressions / _position, anomalies_only + sigma_threshold, and top for one-call movers / losers / outliers reporting.
• gsc_inspect_url - URL Inspection (index verdict, coverage, canonicals).
• gsc_batch_inspect_urls - inspect up to 25 URLs, per-URL failures collected.
• gsc_list_sitemaps - registered sitemaps and their status.
• gsc_submit_sitemap - submit a sitemap (write, un-gated; needs the writable scope). Accepts either sitemap_url (friendly) or feedpath (raw API field).
• gsc_request_indexing - request (re)crawl via the Indexing API (write, un-gated). Accepts singular url or urls.

Query intelligence (v0.2.0)

• gsc_query_opportunities - queries already ranking top N with below-target CTR. Title and meta optimization candidates.
• gsc_query_gaps - queries that draw impressions but barely any clicks. Content opportunity signal.
• gsc_new_queries - queries appearing in the current window with no prior impressions. Emerging topics.
• gsc_top_pages_by_query - which pages rank for a specific query. The cannibalization audit input.

Multi-property + lifecycle (v0.5.0)

• gsc_portfolio_summary(days, include?, exclude?) - multi-property fleet view. Per-property one-row summary (clicks, impressions, CTR, position) for the last N days, plus a portfolio-level rollup. Honors optional include / exclude filters. The single fastest answer to "how is the whole portfolio doing?" across agency or multi-brand setups.
• gsc_trending_pages(days, limit) - pages whose impressions grew most over the last N days vs the prior N days. Wrapper on gsc_compare_periods with dimensions=["page"], sort_by="delta_impressions", sort_dir="desc".
• gsc_decaying_pages(days, limit) - same wrapper, ascending sort. Pages to rescue.
• gsc_coverage_audit(urls, site_url?) - heuristic coverage audit. The GSC Index Coverage report is not exposed in the API; this tool takes a user- supplied URL list (typically pulled from a sitemap) and bulk-inspects each, then rolls up verdicts (PASS / PARTIAL / FAIL) and coverage_state frequencies.

Content intelligence (4)

• content_opportunities(site_url?, days?, count?, impressions_min?) - ranks data-grounded content topics from your own Search Console data: fuses CTR-vs-expected gap (curve self-calibrated from your own per-position CTR), striking-distance position, demand, and momentum into a transparent opportunity score; flags cannibalization. If a GA4 property is configured, it also weights each topic by the organic conversions its top page already drives (up to +50%), so topics that convert rank higher; filters_applied.ga4_value_status reports whether that ran and why (applied / no_ga4_property / ga4_unreachable / no_conversions). Prioritizes demand you already have; does not do cold-start keyword research or write the content. Pairs with the content workflow prompts below. (GA4 weighting v0.7.3) v0.9.0 adds an additive per-candidate winnability block (banded: striking-distance + topical- proximity, GSC-personalization tier; existing fields unchanged).
• content_brief_data(target_query, competitor_urls?, topic?, site_url?, days?) - data-wired backing for a content brief: fetches the competitor pages (or your own GSC-ranking pages as a fallback) and returns the heading union, median word-count floor, schema types, and entity coverage, plus the 2026 GEO writing directives and validation rules. The host writes the prose; SEOMonster brings rules + evidence. Backs the content_brief prompt. (v0.9.0)
• topic_cluster_map(cluster_path | pillar_url, site_url?, days?, impressions_min?)
  • maps a content cluster from your own GSC data and surfaces missing subtopics. Classifies each cluster query into defend / optimize / create / monitor by demand and best position; the create quadrant is your missing-subtopic list. Flags cannibalization. GSC-only; honest about the ~47% query anonymization. (v0.9.0)
• rank_change_attribution(url | urls, change_date, query?, site_url?, pre_days?, post_days?, gap_days?, control_scope?)
  • estimates whether an on-site change moved a page's clicks via difference-in-differences against a matched control group (never a naked before/after). Returns an estimated lift with a 95% CI, a three-state verdict (likely_positive / likely_negative / inconclusive), and a confounders block that auto-detects the 2025 GSC data-regime breaks (impression bug, num=100) and downgrades position reliability. Observational, not causal -- a server-side split test is the only true causal test. GSC-only. (v0.9.0)

AI / GEO citation (3, v0.9.0) - whether the AI answer surfaces reach and cite you.

• ai_citation_readiness(url) - is a page structured to be extracted/cited by LLM answer engines? Leads with a render-blindness check (GPTBot / ClaudeBot / PerplexityBot fetch but do not run JS, so a client-rendered SPA is invisible to them), then scores evidence-backed signals (statistics, quotations, cited sources, no keyword-stuffing). schema.org / FAQ / llms.txt are reported as informational only -- the 2026 evidence does not support them as AI-citation drivers, so they are not scored. Free, HTTP-only.
• ai_referral_overview(property_id?, site_url?, days?) - first-party AI traffic: GA4 referral sessions from AI apps (the native ai-assistant channel plus a configurable source-host regex) and AI-crawler robots coverage (GPTBot, ClaudeBot, PerplexityBot, ...). Surfaces the ~70% dark-traffic undercount and keeps AI-Overview clicks (counted as Organic) separate. Free.
• ai_citation_track(prompts, brand, brand_domains?, competitors?, engines?, samples?)
  • sampled brand mention + citation share-of-voice across AI engines (Perplexity / OpenAI / Anthropic / Gemini APIs + Google AI Overviews via DataForSEO) for a managed prompt set, vs competitors. N samples/prompt (default
  7. with a 95% CI, share-of-voice, and run-to-run volatility -- NOT an "AI rank" (single runs are statistically meaningless). Discloses that developer-API output differs from the logged-in consumer UI and that AIO has no API. Paid + non-deterministic. Needs at least one engine key and/or DataForSEO.

Keyword discovery (3, v0.9.0) - find terms you don't already rank for.

• gsc_keyword_expand(candidates, site_url?, days?, impressions_min?) - you (the host) brainstorm candidate terms from your winning queries; this grounds each against your own Search Console data (footprint covered / thin / none) with a sibling-strength confidence band. "none" = no VISIBLE footprint (GSC hides ~75% of impressions), so net-new terms are scored hypotheses. Free.
• serp_adjacency_expand(seeds, include_paa?) - expand seed terms into adjacent terms. FREE core: Google Autocomplete (no key). Optional People-Also-Ask + related searches via DataForSEO. Returns per-seed suggestions plus the aggregated net-new terms; degrades gracefully without a key.
• keyword_universe(target_domain?, competitors?, keywords?, limit?) - optional, paid. Core value: the competitor keyword GAP (DataForSEO Domain Intersection; no Google equivalent). Optional search volume / difficulty / intent via a provider chain (DataForSEO, else Google Ads volume-only). External volume is a degraded directional signal -- a tiebreaker, never a gate.

Google Analytics 4 (7)

• ga4_run_report - the workhorse: arbitrary dimensions/metrics/date range, optional dimension filter and ordering.
• ga4_top_landing_pages - top landing pages, organic-only by default.
• ga4_traffic_by_channel - sessions/engagement/conversions by channel group.
• ga4_organic_search_overview - organic totals plus a day-by-day trend.
• ga4_setup_audit(property_id?) - read-only SEO-measurement-readiness audit: web data stream, key events, data retention, content-group dimensions, and (v0.7.4) enhanced measurement, internal site search, and Google Signals. Severity-graded with a benign exception per finding. Uses the GA4 Admin API over REST (analytics.readonly; no extra dependency). (v0.7.0)
• ga4_site_search(days?, limit?) - internal site-search query report (a direct content-gap signal); honest envelope when no real search terms. (v0.7.1)
• ga4_landing_page_conversions(days?, organic_only?, limit?) - organic landing pages ranked by conversions. (v0.7.1)

PageSpeed Insights (2)

• psi_analyze - Lighthouse scores, lab Core Web Vitals, and field (CrUX) Core Web Vitals for a URL. Defaults to the mobile strategy. Field data carries a field_data_note: Google is deprecating PSI field data, so use crux_snapshot / crux_history for durable field metrics.
• psi_opportunities(url, strategy?) - the actionable Lighthouse "opportunity" audits (with estimated savings) plus the SEO-category audits, severity-graded. Lab data only. An on-page-basics checklist, not a ranking predictor. (v0.7.1)

Cloudflare (13)

• cf_list_zones - zones the token can see.
• cf_zone_info - status, plan, name servers for a zone.
• cf_list_dns - DNS records (read-only); useful for verifying canonical host and TXT verification records during migrations.
• cf_web_analytics - read-only edge Web Analytics (RUM), to compare against GA4. Cloudflare returns host: null for some sites; pass the site_tag to look those up explicitly.
• cf_purge_cache - purge specific URLs (gated).
• cf_purge_cache_all - purge an entire zone (gated + confirm token).
• cf_settings_audit(zone?) - read-only audit of SEO-relevant Cloudflare zone settings (SSL mode, Always-Use-HTTPS, HSTS, Automatic HTTPS Rewrites, Brotli, cache TTL). Severity-graded with a "verify, not fail" discipline because CF cannot see the origin; HSTS is never a hard failure. Needs Zone Settings Read on the token. Each finding carries a machine-readable fix hint (the exact cf_settings_update setting + recommended value) to chain audit -> fix. (v0.7.1)
• cf_settings_update(settings, zone?, confirm?, acknowledge_hsts_risk?, dry_run?)
  • write the SEO/crawl/security settings the audit grades (SSL mode, Always-Use- HTTPS, Automatic HTTPS Rewrites, Brotli, browser cache TTL, HSTS), closing the audit -> remediate loop. Gated. ssl_mode or any HSTS-raise needs confirm=<zone> (HSTS-raise also needs acknowledge_hsts_risk=true); validates locally, supports dry_run, and re-runs the audit so you see the finding clear. Needs Zone Settings:Edit (vs the audit's Read). (v0.7.10)
• cf_list_redirects(zone?) - list a zone's single (dynamic) redirect rules plus the account's Bulk Redirect lists (read-only). Call before any redirect write so nothing is clobbered. (v0.7.8; bulk lists added v0.7.9)
• cf_create_redirect(source, target, status_code?, ...) - create one edge redirect (e.g. a 301 for a renamed URL). Gated. Pre-flights the target (no redirecting to a dead URL), refuses loops/duplicates, supports dry_run. (v0.7.8)
• cf_delete_redirect(rule_id, zone?) - remove a single-redirect rule by id (rollback for cf_create_redirect). Gated. (v0.7.8)
• cf_bulk_redirect_upsert(items, list_name, confirm, ...) - create/append many redirects at once via an account-level Bulk Redirect List (for migrations). Gated + a confirm token equal to list_name. Validates every item locally first and rejects the whole batch on any bad item (never half-applies); supports dry_run. (v0.7.9)
• cf_managed_robots(action, zone?, ...) - get / configure / disable Cloudflare's managed robots.txt and Content-Signals policy (these ride on the zone's Bot Management config). action="get" reads the current state (read-only, un-gated). action="configure" sets the managed robots.txt (managed_robots), the Content-Signals variant (cf_robots_variant: off / policy_only), and the AI-bot blocking levers (ai_bots_protection, content_bots_protection, crawler_protection). action="disable" turns the managed robots.txt and the policy back off. Managed robots.txt and the Content-Signals policy are mutually exclusive in Cloudflare, so the valid combinations are managed_robots=true + cf_robots_variant="off" (managed robots.txt) OR managed_robots=false + cf_robots_variant="policy_only" (the policy); the tool rejects the invalid combo locally with INVALID_INPUT. A custom Content-Signal line (e.g. from robots_ai_posture) is not a managed option - put that in your origin robots.txt. Writes are gated, need confirm=<zone>, and support dry_run; reads are safe (GET -> overlay -> PUT, so nothing else in the config is clobbered). Every response carries a caveat separating the stated-preference signals (Content-Signals, honored only by adopting crawlers and ignored by Googlebot) from the levers that actually enforce at the edge. Needs Bot Management:Edit for writes (Read for get). (v0.8.2)

IndexNow (2, v0.2.0)

• indexnow_submit(url) - submit a single URL to Bing, Yandex, Naver, Seznam, Yep. Complements (does not replace) gsc_request_indexing, which only talks to Google. Requires SEO_MCP_INDEXNOW_KEY plus a verification file at https://<your-host>/<key>.txt (see IndexNow setup for the full key + file format + same-host rules).
• indexnow_bulk_submit(urls) - up to 10,000 URLs sharing one host in a single POST. Mixed-host batches are rejected client-side with INVALID_INPUT before any network call. The SEO_MCP_INDEXNOW_KEY_LOCATION env var overrides the default verification-file URL when your CDN rewrites /key.txt paths.

Technical SEO (8, v0.3.0) - no credentials needed; built-in HTTP client.

• inspect_meta(url) - on-page surface in one call: title, meta description, meta robots, canonical, Open Graph + Twitter Card tags, hreflang, H1 count.
• check_canonical(url) - canonical-link audit: self-referential / cross-host / protocol-mismatched / trailing-slash drift / canonical target reachable.
• mixed_content_check(url) - parses an HTTPS page and flags any http:// references (img / script / iframe / form action / srcset). No-op for http://.
• redirect_chain_audit(url, max_redirects=10) - walks the chain hop by hop. Flags long chains, protocol downgrades, loops, non-2xx terminus.
• robots_txt_validate(site_url, probes?) - parses robots.txt (per-group rules + sitemaps + Content-Signals), optionally verdicts (user_agent, url) probes using RFC 9309 longest-match (matches what Google + Bing actually do, not stdlib's first-match). Also detects a stale edge-cached robots.txt (cache-bust comparison; re-parses from the fresh content) and a Cloudflare Managed robots.txt / Content-Signals policy overriding your origin - catching false-clean robots on migrated/CF-fronted sites. (v0.8.0)
• sitemap_validate(sitemap_url) - validates a sitemap or sitemap-index XML, counts entries, flags oversize + cross-host + missing lastmod. .gz transparent.
• sitemap_health(sitemap_url, sample_size=25) - sample-HEAD audit. Status histogram + first non-2xx examples.
• robots_ai_posture(goal?, sitemap_url?) - deterministic, offline advisor for the Content-Signals levers (search / ai-input / ai-train). Takes a business goal (content_authority default / maximize_visibility / protect_ip), recommends a posture with a plain-language rationale, lays out the trade-off alternatives, and emits a ready-to-apply artifact: the Content-Signal: directive line plus a full suggested robots.txt. No network, no writes. Every response carries the mandatory caveat that Content-Signal is honored only by adopting crawlers, is ignored by Googlebot, and is not a ranking factor. (v0.8.1)

Chrome UX Report (2)

• crux_history(url? | origin?, form_factor?, metrics?) - 25 weeks of p75 Core Web Vitals via the CrUX History API. Reuses PSI_API_KEY; works anonymously at a tighter rate limit when no key is configured.
• crux_snapshot(url? | origin?, form_factor?) - the current p75 Core Web Vitals (point-in-time, vs the history). Each metric reports a category (GOOD / NEEDS_IMPROVEMENT / POOR); the rolled-up rating is overall_category. Time metrics use p75_ms; the unitless CLS uses p75. Small origins return a no_data envelope. (v0.7.1)

Structured data + cross-site + on-page (7) - no new credentials (the v0.9 SERP auto-fetch is optional).

• inspect_schema(url) - extract every JSON-LD block from a page; report the schema.org @type counts and a sample entity per type.
• validate_schema(url, types?) - verdict each JSON-LD entity against the Google Rich Results required-field set. Covers Article, NewsArticle, BlogPosting, Product, FAQPage, BreadcrumbList, Organization, LocalBusiness, Event, Review, Recipe. Per-entity verdict plus missing_required and missing_recommended lists.
• hreflang_consistency_check(urls) - cross-page hreflang audit on a user-supplied URL set. Flags missing reciprocity, broken hreflang targets, duplicate hreflang on one page, missing self-link, missing x-default when there are 3+ language variants.
• internal_link_graph(start_url, max_depth=2, max_pages=50) - small BFS crawl within the same host. Per-page in-degree + out-degree, orphan pages, broken internal links, depth distribution. Hard caps (max_depth <= 4, max_pages <= 200) so a misuse never melts the host.
• lighthouse_budget(url, budget) - wraps psi_analyze and verdicts the results against a budget dict, e.g. {performance: 80, LCP_ms: 2500, CLS: 0.1}. Per-metric pass/fail and an overall verdict. Useful as a CI / pre-deploy gate inside an LLM session. Reuses PSI_API_KEY.
• internal_link_recommend(start_url, site_url?, days?, position_min?, position_max?, relevance_floor?, limit?)
  • recommends specific source->target internal links from high-in-degree pages to GSC striking-distance pages (default position 8-20 with real impressions), with anchor text. Ranks sources by lexical relevance + internal authority, skips pages that already link the target, balances anchor text, and never suggests nofollow. Built on internal_link_graph + GSC. Free. (v0.9.0)
• onpage_serp_gap(target_url, query?, competitor_urls?, max_competitors?) - the headings, entities, and schema the top SERP results have that a target page lacks, turned into on-page actions. FREE with caller-supplied competitor_urls; optional DataForSEO SERP auto-fetch by query, which also returns winnability signals (serp_composition AI-Overview / UGC zero-click risk) and, with Open PageRank, competitor domain authority. Surfaces information gain, not just parity. Boilerplate/nav headings are filtered out (pattern-class chrome filter). (v0.9.0; F6 fix v0.9.1, F1 generalized v0.9.2)

Every tool's tools/list entry carries the MCP standard annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) so MCP hosts can decide what to auto-approve and what to confirm.
