Key Gotchas

1. Multilingual works perfectly — pass language: "de" for German, language: "tr" for Turkish, etc. Titles must match the target language's article title (e.g. İstanbul for Turkish)
2. `section_index` is numeric — use wikipedia_get_sections first to discover the index, then wikipedia_get_article with section_index to read just that section
3. Nonexistent pages return MCP error (code -32001) with a helpful recovery hint: "Use wikipedia_search to find the correct article title"
4. Nonexistent search queries return 0 results (no error, graceful empty response)
5. Search returns `totalResults` count — useful for pagination planning (e.g. "Alan Turing" matches 2,351 articles)
6. Summary includes thumbnail URL — direct wikimedia commons link, useful for displaying article images
7. `wikipedia_get_languages` returns full URLs — clickable links to each language edition
8. Nearby search returns distance in meters — e.g. 10.7m from Charing Cross coordinates to the equestrian statue article
9. Server emits JSON logs to stderr — filter stderr in production; stdout is clean MCP protocol
10. First call ~2s (cold start + network), subsequent calls 250ms-1s depending on article size
