Wikipedia MCP

Access Wikipedia via Model Context Protocol (MCP). No API key required.

Tools

All tools accept an optional lang parameter (default en; supported: en, de, es, fr, ja, zh, pt, it, ru, nl), except media_search — Wikimedia Commons is language-independent, so it takes no lang. Note: quote accepts the parameter for API consistency but is currently English-only (curated list).

Installation

1. Install dependencies

pip install -r requirements.txt

(Requires Python 3.10+ and requests>=2.28.0)

2. Find your install path

The MCP server lives at <install-dir>/src/server.py.

ls ~/.openclaw/workspace/skills/wikipedia/src/server.py

3. Add to mcporter

Add to ~/.openclaw/workspace/config/mcporter.json:

{
  "mcpServers": {
    "wikipedia": {
      "command": "python3",
      "args": ["<path-to>/src/server.py"]
    }
  }
}

Replace <path-to> with the actual install location from step 2.

4. Test

Data Source

Uses Wikipedia's free public REST API — no API key required.

• Search: MediaWiki Action API
• External links: MediaWiki Action API (prop=extlinks)
• Infobox: MediaWiki Action API (action=parse + prop=wikitext), with local wikitext parsing (no new dependencies)
• References: MediaWiki Action API (action=parse + prop=text), extracting the rendered <ol class="references"> citation list (no new dependencies)
• Summary / Random / Featured / Picture of the Day: REST API v1 (/api/rest_v1/...)
• Media of the Day: MediaWiki Action API on Commons (date-stamped Template:Motd/YYYY-MM-DD + imageinfo metadata)
• Related articles: MediaWiki Action API (search generator with morelike: scoring)

Notes

• User-Agent is wikipedia-mcp/1.1.24 per Wikipedia API etiquette
• All responses include links back to the source article
• dino_fact falls back to a random species if the requested one isn't found (instead of erroring)
• featured_article returns today's curated Featured Article — great for daily content hooks
• picture_of_the_day returns Wikimedia Commons' Picture of the Day from Wikipedia's featured feed — the visual counterpart to featured_article. Accepts an optional date (YYYYMMDD, default today UTC) to browse past pictures. Returns the embedded thumbnail preview, file name, photographer/artist, license, description, and links to the full-size image + Commons file page. image/media_list cover article-specific media; this covers the editorially curated daily pick.
• media_of_the_day returns Wikimedia Commons' Media of the Day — the curated daily video or audio clip, the motion-and-sound counterpart to picture_of_the_day. Accepts an optional date (YYYYMMDD, default today UTC) to browse past picks; some dates have no Media of the Day and return a clear message. Returns the media kind, duration, a preview thumbnail (video) or listen link (audio), file name, artist, license, description, and links to the direct file + Commons file page.
• article_extract returns the full plain-text article (vs summary's short extract + thumbnail) — use when you need more than a summary
• article_sections returns the article's table of contents — section number, heading text, and nesting level — so callers can navigate long articles (50KB+ body) by picking the section they want before committing to article_extract. Pairs with summary (lead), article_sections (structure), article_extract (full body).
• section_text reads a single article section as plain text — the follow-up to article_sections: pass a 1-based section number (0 = lead/intro), a hierarchical number like 2.1, or a heading name (case-insensitive, with close-match suggestions on typos). Strips inline CSS, citation markers, and edit links while keeping paragraph structure; the link at the bottom deep-links to the section. Use it instead of article_extract when you only need one part of a long article.
• on_this_day returns historical events for today's UTC date from Wikipedia's "On This Day" feed — pairs with featured_article for daily "today in history" content hooks
• deaths_on_this_day returns notable deaths for today's UTC date — the deaths-only companion to on_this_day. Pairs with on_this_day (events) and featured_article (today's long-form) for a full "today in Wikipedia" daily digest. Useful for "in memoriam" content hooks and obituary-style social posts.
• births_on_this_day returns notable births for today's UTC date — the births companion to on_this_day (events) and deaths_on_this_day (deaths), completing the "today in Wikipedia" trio. Useful for "born on this day" content hooks and birthday round-ups.
• categories returns Wikipedia categories for an article (hidden/maintenance categories filtered) — useful for taxonomy-based discovery beyond text search
• links returns the article's outgoing Wikipedia links (main namespace only) — graph-style discovery showing which genera, people, and concepts an article references
• backlinks returns the article's incoming Wikipedia links (what links here) — the inverse of links. Shows which other articles reference this one (cultural mentions, scientific citations, comparative anatomy pages, etc.). Same main-namespace filtering.
• nearby returns Wikipedia articles geographically near a location, with distances — location-based discovery. Anchor by article title (e.g. 'Eiffel Tower', uses that article's coordinates so no geocoding service is needed) or by explicit lat/lon. Radius in meters (default 1000, max 10000), main-namespace only. Useful for travel research and "what's notable around here" questions.
• translations returns all language editions of an article (langlinks) — the other-language titles that Wikipedia knows about. Complements the one-way lang parameter used by other tools: every tool can query a single language, but only translations reveals the article's full language coverage so callers can pick a target language to fetch next. Useful for translation research (full coverage vs. stub languages), cross-language content sourcing, and language-coverage analysis.
• pageviews returns daily view counts for an article over a date range (default last 7 days) — popularity research, trending topics, historical interest spikes. Uses Wikimedia's pageviews REST API.
• news returns today's editorially-curated current events from Wikipedia's Main Page "In the news" block — pairs with featured_article (today's long-form) and on_this_day (historical) for a full "today in Wikipedia" content hook
• top_reads returns the most-viewed articles on Wikipedia for a given date (default yesterday UTC) — answers "what is everyone reading right now" while pageviews answers "how is this specific article trending". Filters out Main_Page, Special:Search, Portal:Current_events, etc. so the result is real articles only.
• image returns the article's lead image as URLs (300px thumbnail + full-size original) without summary prose — useful for embedding the image elsewhere (cards, slide decks, Telegram hero images). summary embeds the thumbnail inline; image exposes both URLs separately.
• media_list returns every media item (images, videos, audio) the article uses — not just the lead thumbnail. Each entry has file title, type, caption, and thumbnail URL; lead media is marked with 🏆 so callers can skip it when they already have it via image. Uses Wikipedia's REST /page/media-list endpoint (structured JSON, no HTML parsing). Pairs with image (lead only) — use image for the headline thumbnail, media_list for the full inventory (gallery generation, fact-checking, slide decks, audits).
• media_search is the topic-based counterpart to image/media_list: full-text search across Wikimedia Commons' File: namespace by keyword, so you can find freely-licensed media for a topic with no article yet (blog posts, slide decks, README hero images). Each result has file title, media type + dimensions, 320px thumbnail and full-size URLs, license short name, artist, description snippet, and a Commons file-page link. filetype filters to image (default: photos + diagrams/SVGs), video, audio, or all; limit clamps to 50. Uses the read-only Commons action API (generator=search) — GET-only, no new dependencies. Language-independent, so no lang parameter.
• infobox returns the article's structured fact box as a markdown field/value table — the fastest path to a concrete fact ("who founded X?", "population of Y?") without reading prose. Parses raw wikitext from the read-only parse API locally (balanced-brace template extraction, no new dependencies): wikilinks flatten to plain text, citations/HTML are stripped, nested templates collapse to their values, birth/death-date templates render as YYYY-M-D. Fields capped at 50, values at 400 chars. Reports clearly when an article has no infobox. Pairs with summary (prose gist) and article_extract (full text) — use infobox for facts, the others for narrative.
• article_quality returns Wikipedia's quality assessments for an article — the WikiProject grades (FA/FL featured, A, GA good, B, C, Start, Stub) plus importance ratings, with an overall class (best grade assigned) and per-project table. The encyclopedia's own trust signal: check it before relying on an article (GA/FA passed formal review; a Stub is a skeleton). Read-only pageassessments action API, no new dependencies. Note: assessment is only enabled on some language editions (en works; e.g. de reports no data).
• related_articles returns articles Wikipedia's own search engine judges most similar to a given title (MoreLikeThis scoring over article text and link structure) — the "what should I read next" discovery tool. Unlike links (raw outgoing links on the page) or categories (shared topic buckets), this is a similarity ranking: given "Velociraptor", expect dromaeosaurids, feathered dinosaurs, and "Deinonychus". Each entry shows the short description and a thumbnail; the source article itself is excluded. Read-only action API search generator, no new dependencies.
• contributors answers "who writes this article" — the most active recent editors. It tallies up to 500 recent revisions (read-only action API, GET only, no new dependencies) into a ranked table: top named editors by edit count with their share of sampled edits and user-page links, plus the anonymous (IP) edit share, and the sampled date span. A provenance companion to article_quality (the grade earned) and revisions (the raw log): a page tended by veteran caretakers reads differently from one mostly touched by drive-by IP edits, and the top names are who to credit — or to check for conflicts of interest. Follows redirects; limit clamps to 20.
• references answers "what does this article cite" — the article's bibliography. It reads the rendered reference list from the read-only parse API (GET only, no new dependencies): each citation's cleaned text plus the off-wiki URLs it points to (DOI, publisher, archive, primary-source links), with internal wikipedia.org/wikimedia.org links filtered out. Backlink markers (^ a b c / ↑) are stripped and long citations truncated at 420 chars. The verification companion to external_links (which dumps every off-wiki link on the page, including templates): references returns only the sources actually cited — the bibliography you'd hand to a fact-checker. Pairs with article_quality (trust signal) and contributors (who wrote it) for a full "can I rely on this article?" audit. Reports clearly when an article has no reference list. Follows redirects; limit clamps to 50.
• revision_diff answers "what did this edit actually change" — give it two revision IDs (from revisions) and it returns a plain-text unified diff of the article's wikitext between them, each side labelled with timestamp, editor, and edit summary, plus a link to the on-wiki side-by-side view. Fetches both revisions in one read-only action API call and diffs locally with stdlib difflib (no new dependencies); limit clamps diff lines (default 100, max 500). The edit-auditing companion to revisions (the log): review edits before trusting a new paragraph, audit what a breaking-news change removed, spot stealth rewrites.
• disambiguation answers "which article did you mean" — given an ambiguous title like 'Mercury' or 'Apple', it verifies the disambiguation marker via pageprops and returns the page's own option list (article title + one-line description), grouped by section (e.g. Companies, Film and television), main-namespace links only. Reports clearly when the title is a regular article (use summary instead) or doesn't exist. The disambiguation companion to search: call this when search/summary land on an ambiguous page, pick the right candidate, then fetch it with summary or article_extract; limit clamps options (default 30, max 100).
• user_contribs answers "what has this editor been doing" — the reverse angle of contributors (which profiles an article's editors): given a username or IP address, it shows their latest edits across the encyclopedia via the read-only list=usercontribs action API. Each entry shows the page link, timestamp, byte-size delta, edit comment, diff link, and flags for new pages, minor edits, and edits still current. The header reports the account's registration date and lifetime edit count (or states plainly when the name has no registered account — an IP can still have contributions). Use it to profile a top contributor surfaced by contributors, audit an anonymous IP's activity, or spot single-purpose accounts whose edits are confined to one topic (a conflict-of-interest tell). namespace scopes the search (default 0 = articles); limit clamps to 50.
• simple_summary answers "explain it simply" — it fetches the same topic from Simple English Wikipedia (simple.wikipedia.org), where articles are rewritten in short sentences with common words, and renders it in the same title + summary + thumbnail + read-more shape as summary. The accessibility companion to summary/article_extract: reach for it for kids, ESL readers, or a quick low-jargon intuition of a dense topic, then graduate to summary for the full article. Reports clearly when no Simple English article exists for the topic. No lang parameter — Simple English is its own wiki.
• citation_needed answers "which claims lack a source" — the flip side of references (which lists what an article cites): it finds statements Wikipedia editors have flagged with {{citation needed}} tags. Two angles: pass article to scan that article's wikitext via the read-only parse API and extract each tagged sentence with its tag date (wiki markup stripped, section headers and reference tags removed), or pass topic (or neither) to run a read-only insource:"citation needed" search returning tagged articles with the flagged claim's snippet. Use it to find sourcing work as an editor, or to spot the shakiest claims in a topic you're researching. Reports clearly when an article has no tags or doesn't exist; article takes precedence when both are given; limit clamps to 25. Tag-name matching is English-Wikipedia-centric (lang accepted for API consistency).
• talk answers "what are editors discussing" — the behind-the-scenes view of an article. It reads the article's Talk: page wikitext via the read-only action API (GET only, no new dependencies), splits it into discussion threads, and returns the most recently active ones: each thread's heading, last-activity timestamp, signed-comment count, and an excerpt of the latest comment (wiki markup stripped, closed-thread banners removed). Automated maintenance notices (redirect/deletion discussions) are filtered out; unsigned template-only pages report clearly. Use it to find controversies, open questions, and editorial disputes — the discussion companion to contributors (who edits) and article_quality (how the article is graded) for a full "can I rely on this article?" audit. Follows talk-page redirects; limit clamps to 15. Talk-page conventions are English-centric (lang accepted for API consistency).
• article_flags answers "what do editors think is wrong with this article" — the warning labels. It reads the article's wikitext via the read-only parse API (GET only, no new dependencies) and matches maintenance-banner templates against a curated English list (POV, Original research, Unreferenced, More citations needed, Cleanup, Disputed, Fringe theories, Notability, Conflict of interest, Outdated, and ~40 more, including section-scoped variants like {{POV section}}). Each flag shows its tag date, its location (article top or section heading), and a plain-language meaning; the {{Multiple issues}} wrapper is unpacked into its individual flags, and non-editorial templates (infoboxes, citation formats, date styles) never leak in. Reports clearly when an article carries no flags. The trust-signal companion to article_quality (the grade), citation_needed (unsourced claims), and talk (editor discussion) for a full "can I rely on this article?" audit. Banner names are English-Wikipedia-centric (lang accepted for API consistency); limit clamps to 25.
• citation_sources answers "where does this article's evidence come from" — the diversity lens on the bibliography. It reads the article's rendered reference list via the read-only parse API (GET only, no new dependencies), groups every off-wiki link by registrable domain (so news.bbc.co.uk and www.bbc.co.uk both count as bbc.co.uk, via a hand-curated multi-level-suffix list — no public-suffix dependency), and returns a ranked publisher table with each domain's citation count and share of linked references, capped by a plain-language verdict: diverse / balanced / top-heavy / lopsided / thin. Also reports the share of citations with a Wayback Machine / archive.org copy (link-rot insurance) and the share pointing at DOI-linked scholarly works. The companion to references (which lists the full bibliography) for the "can I rely on this article?" audit, alongside article_quality (the grade), article_flags (editorial warnings), and citation_needed (unsourced claims). Follows redirects; limit clamps to 30 domains. Reports clearly when an article has no references or none link off-wiki.
• article_path answers "how do these two articles connect" — the six-degrees game. Given start and target titles, it searches Wikipedia's link graph for the shortest chain of blue links between them (e.g. Banana → Africa → Anatolia → Trojan War), using only read-only action API GETs (no new dependencies): 1 hop checks a direct link, 2 hops intersects the start's outgoing links with the pages linking to the target (every middle found is a real start → middle → target path), and 3 hops expands a bounded sample of the start's links (max 25 pages, 500 links each) looking for one landing on a page that links to the target. Follows redirects (so "USA" → "United States" is 0 hops) and reports exactly what was scanned. The discovery companion to links (raw outgoing links) and backlinks (every page linking in): play six-degrees, trace how topics connect, or find the surprising middle article bridging two distant subjects. max_hops clamps to 1–3 (default 2); reports clearly when no path is found within the budget.
• article_at_date answers "what did this article say on that date" — the time machine. Given a title and a YYYY-MM-DD date, it finds the latest surviving revision at or before the end of that day via the read-only action API (rvstart + rvdir=older), then reads that revision's clean lead text through TextExtracts (no infobox/navbox noise), returning it with the revision ID, timestamp, editor, edit summary, and a permanent link to the exact revision. Reports clearly when the article didn't exist yet (naming its first surviving revision), when the title doesn't exist, or when the date isn't YYYY-MM-DD. Follows redirects. The history companion to summary (the article as it reads now), revisions (the raw edit log), and revision_diff (what changed between two revisions): see what an article claimed before an event, or how a lead evolved.
• Multi-language: pass lang to any tool to query de/es/fr/ja/zh/pt/it/ru/nl Wikipedia
