Tools & Capabilities Breakdown
Citation Intelligence Tools (26)
citations_check
Return URLs cited by an AI engine (Perplexity, Claude, ChatGPT, Gemini, or Bing) for a query. Use this when an agent or user wants to see what sources an AI search engine grounds answers on. Requires at least one engine API key; auto-picks the first available.
domain_am_i_cited
Check whether a domain is cited by an AI engine across a cluster of queries. Returns per-query presence, rank, and a citation-rate summary. Use to measure visibility for a brand, product, or content site in AI search.
signals_ai_overview
Check whether Google shows an AI Overview for a query, and which URLs it cites. Uses SerpAPI (free tier: 100/month). Set SERPAPI_KEY.
domain_cited_for
List queries that the given domain has been cited for, served from the local cache. Build up a corpus by calling check_citations or am_i_cited first; cited_for queries it without spending API budget.
citations_predict
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Citation Intelligence is categorized under Search & Data Extraction and uses a local stdio subprocess. In contrast, Intercept MCP belongs to Search & Data Extraction using local stdio subprocess. Select Citation Intelligence when you need capabilities focused on search & data extraction and Intercept MCP when you require tools for search & data extraction.
Score citation likelihood for a URL from public signals (Wikipedia link presence, schema.org markup, /llms.txt, GitHub and Reddit references, canonical hygiene, HTTPS). No LLM fired - all heuristic. Returns 0-100 score, grade, signal breakdown, and ranked fixes.
panel_track
Save, load, or list named query panels. A panel is a persisted set of queries you want to monitor over time (e.g. editorial-watchlist). Use action=save with queries[] to create, action=load to read, action=list to enumerate. Panels live under <config>/panels/<name>.json.
panel_run
Run a saved panel through am_i_cited and append a timestamped snapshot. Side effects: makes external API calls to the configured AI engine (costs API quota); writes one snapshot file to disk at <config>/snapshots/<panel>/<iso>.json. Requires at least one engine API key (same as am_i_cited). Returns per-query citation presence and a citation_rate summary for the run. Use panel_track to create a panel first; use citations_trend to read the accumulated trend after multiple runs.
report_visibility
Turnkey AI visibility report for a domain across a query set. Composes check_citations over every query (or a saved panel) and returns the metrics AI-visibility trackers sell as a dashboard, in one call: mention frequency (citation_rate), share_of_voice vs competitors, average rank when cited, and brand sentiment from the answer text. Side effects: one check_citations call per query (costs API quota for uncached queries; cached queries are free). Returns structured summary + top_domains + per_query, plus a rendered Markdown report (include_markdown=true) suitable for a public page. Provide queries[] or a panel name. Same engine selection as check_citations.
citations_trend
Report citation rate over time for a panel from stored snapshots. Read-only; cache-only — makes no API calls to any AI engine and costs no API quota. Reads snapshot files from <config>/snapshots/<panel>/. Returns: snapshots[] (one entry per panel_run invocation, each with timestamp and citation_rate), plus per-query deltas (gained/lost/unchanged) comparing first vs last snapshot. Returns an empty series when no snapshots exist yet. No auth required. No rate limits. Use panel_run to accumulate snapshots first; use since to restrict the time window.
competitors_compare
Run predict_citation on 2-10 URLs and return a side-by-side signal table plus a list of signals where the URLs diverge. Use to compare your URL to top-cited competitors for the same query.
signals_wikipedia
List Wikipedia articles that reference the given domain. Read-only. One HTTPS GET to the Wikipedia API (en.wikipedia.org/w/api.php?action=query&list=exturlusage). No auth required; no API keys; no rate limits beyond Wikipedia's public API fair-use policy (~1 request/second). Returns article titles and URLs. Wikipedia backlinks are the highest-lift signal for LLM training corpora — a domain cited from Wikipedia is far more likely to appear in AI training data and citation pools. Use lang to query non-English Wikipedias.
audit_sitemap
Fetch a sitemap.xml (or sitemap index) and run predict_citation on every URL. Returns results sorted worst-score-first. Surfaces systemic issues across a whole site in one pass. Zero engine keys needed.

Intercept MCP Tools (5)
fetch
Fetch a URL and return its content as clean markdown. Handles Twitter/X tweets, YouTube videos (with transcripts), arXiv papers, PDFs, Wikipedia articles, and GitHub repos/files/issues/PRs/releases directly. Direct image URLs (png/jpeg/gif/webp) are returned as an image block for vision. Otherwise checks a shared cache, then falls back through a multi-tier chain: Jina Reader, web archives (Wayback, archive.ph, Arquivo.pt), raw fetch, RSS, CrossRef, Semantic Scholar, HackerNews, Reddit, OG meta. Long pages are truncated at maxLength characters — paginate with startIndex. Results are cached for the session; pass noCache to force a live fetch.
fetch_batch
Fetch up to 10 URLs in parallel and return each as clean markdown. Same handler/fallback chain as the fetch tool, with a smaller per-URL length budget. Use after a search to pull several sources in one call.
research
Search the web and fetch the content of the top results in one call. Returns the full content of each result as markdown, ready to summarize or compare. Use this instead of separate search + fetch calls when researching a topic.
search
Search the web and return results. Uses Brave Search API if BRAVE_API_KEY is set, otherwise falls back to SearXNG and then DuckDuckGo. Supports domain filtering (site), freshness, and pagination (page).
extract
Extract specific values from a web page as JSON instead of markdown prose. Provide CSS selectors to pull named fields (text or an attribute, first match or all), and/or set tables:true to convert every HTML table to arrays of row objects. Use this when you need particular data (prices, lists, specs, tabular data) rather than the whole page. Honors per-domain auth and proxies.
