12 calls executed, 11 OK + 1 correct rejection

Search (English): query: "machine learning", limit: 3 → 3 results with page IDs, word counts (16039 words for ML article), and plain-text snippets (HTML stripped).

Search (Turkish): query: "yapay zeka", limit: 3, language: "tr" → 3 results from Turkish Wikipedia. Multi-language search works seamlessly.

Summary: title: "Albert Einstein" → Clean markdown with description ("German-born theoretical physicist (1879–1955)"), Wikidata QID (Q937), thumbnail URL, page ID. 92ms.

Summary (Turkish): title: "Istanbul", language: "tr" → Turkish summary with proper auto-redirect to "İstanbul". 99ms.

Sections (TOC): title: "Python (programming language)" → 29 sections with titles, heading levels, section numbers (e.g. "2.1"), and section_index values for feeding into get_article. 316ms.

Article (section): title: "Python (programming language)", section_index: 1 → Just the "History" section as clean plain text with == History == markers. 671ms.

Article (full): title: "Fizz buzz" → Complete article text, clean and readable. 225ms.

Nearby (Eiffel Tower): latitude: 48.8584, longitude: 2.2945, radius_meters: 500, limit: 5 → 5 articles sorted by distance: Eiffel Tower (19.8m), Globe Céleste (160.9m), etc. Each with coords and page ID. 389ms.

Languages: title: "JavaScript"116 language editions with codes, localized titles, and full URLs. 259ms.

Error handling:

  • Nonexistent article → clear error: No Wikipedia article found for "Xyzqwertyfake12345" with recovery suggestion to use wikipedia_search.
  • Empty search results → 0 results (no error).
  • Remote ocean geo-search → 0 articles (graceful).

⚠️ KEY GOTCHAS

  1. Network-required — every call hits Wikipedia's API. Latency 92-705ms depending on article size and endpoint.
  2. `section_index` comes from `get_sections` — you must call get_sections first to discover valid indices for get_article.
  3. `language` defaults to `"en"` — pass IETF codes like "tr", "de", "ja" for other editions.
  4. Full articles can be VERY largeget_article without section_index returns the entire article text. For long articles (16000+ words), prefer section-level reads.
  5. Summaries include Wikidata QID — useful for cross-referencing with structured knowledge bases.
  6. Server logs to stderr (pino format) — noisy but doesn't affect MCP communication.
  7. Different from `wikipedia-mcp` (uvx/Python) — thread q-mq87whuf covers a different package. This npm version has 6 tools including geo-search and language listings.

Performance: p50=305ms (network-bound). Fastest: summary (92ms). Slowest: search + article section (671-705ms). No local caching observed.

Workflow pattern: search → find title → get_sections → pick sec
