Citable MCP tools 19

  • citable_pricesFree. Lists Citable's SEO endpoints with current per-call USDC prices, plus the wallet that pays: address (the one to fund), walletMode (keypair or sign-in), balanceUsdc and funded. When it is empty, `setup` gives the two ways to fund it — put them to the user. Call this first.
  • citable_connectFree. For people who do not use crypto. Returns a link to open in a browser: sign in at Citable with Google or email, add a few dollars of USDC, click Connect — the agent then pays from that wallet. The link works for 15 minutes; when the user says it is done, call citable_prices to confirm (walletMode becomes sign-in). {status:true} only reports; {reset:true} disconnects and returns to the keypair. The first connect installs Para's SDK under ~/.config/citable/para (about 200 MB, once).
  • citable_keyword_suggestPaid ($0.005 USDC per call). Expands a seed keyword into autocomplete suggestions, related queries and questions, deduped and ranked across Google, YouTube and Bing. Returns `suggestions[]` and `questions[]` with a 0–1 prominence score, the sources each came from, and whether the keyword still contains the seed.
  • citable_onpage_auditPaid ($0.01 USDC per call). Fetches one URL and returns a scored on-page audit: title, meta description, canonical, robots, viewport, lang, heading counts and text, word count, internal/external links, image alt coverage, Open Graph, JSON-LD types, HTTP details, and 15 weighted checks with a 0–100 score. Not charged if the page cannot be fetched.
  • citable_ai_visibilityPaid ($0.05 USDC per engine asked; $0.20 for all four). Asks the AI answer engines (Perplexity, Gemini, OpenAI, Claude — whichever the deployment has configured) a prompt through their official APIs and reports which ones cite the domain: `mentioned`, 1-based `position` in each engine's citation list, and the full cited-domain list per engine. One run per engine — answers vary between runs, so call 2–3 times for signal. Not charged if no engine answers.
  • citable_rank_checkPaid ($0.012 USDC per call). Google organic position of a domain for a keyword via a licensed SERP feed: 1-based `position` (null if outside the checked window), the ranking URL and title, plus the top-10 result list. Not charged if the feed is unavailable.
  • citable_keyword_researchPaid ($0.06 USDC per call). One seed returns keywords AND questions, merged from public autocomplete and the paid keyword index, with search volume, CPC, difficulty and intent attached. Each row says which sources found it — both is the strongest signal. Cheaper than citable_keyword_ideas plus citable_keyword_metrics separately; reach for those only when you want to control exactly what you pay for. Not charged on failure.
  • citable_keyword_ideasPaid ($0.05 USDC per call). Keyword research: one seed returns up to 100 keywords that contain it, each with search volume, CPC, competition, difficulty and intent, ordered by volume. Full-text matched, so results stay on topic. Use citable_keyword_suggest for the exact phrasings people type (no volume), and citable_keyword_metrics when you already have a shortlist. Not charged on failure.
  • citable_keyword_metricsPaid ($0.03 USDC per call, covers the whole batch). Search volume, CPC, competition, keyword difficulty and search intent for 1–20 keywords — licensed clickstream-derived estimates. Answers in request order; unknown keywords return null metrics. Pair with citable_keyword_suggest: expand a seed there, price the shortlist here. Not charged if the metrics feed is unavailable.
  • citable_top_cited_pagesPaid ($0.22 USDC per call). Which pages of a domain AI engines cite most, from an aggregated index of AI answers — per-page mentions, AI search volume, per-engine and per-language splits, plus domain totals. Answers 'what already works on this site — write more of that'. Not charged if the index is unavailable.
  • citable_citability_reportPaid ($0.30 USDC per call; $0.43 bought separately). One call bundles the on-page citability audit, AI visibility across all configured engines, and the domain's top AI-cited pages. Answers: can AI read this site, who cites it today, and which pages already work. Not charged on failure.
  • citable_cited_promptsPaid ($0.25 USDC per call). The real questions AI answer engines cite a domain for, from an aggregated index of AI answers — question, answer snippet, AI search volume, and the exact URL cited. These are observed prompts, never generated ones, so use this to discover what to track instead of inventing them. Repeated observations of one question are collapsed, with `observations` counting them. Point it at a competitor's domain to get the prompts they win and you do not. Not charged on failure.
