wikidata_sparql_query
shallowio.github.cyanheads/wikidata-mcp-server · Verify this server
Execute a SPARQL SELECT query against the Wikidata Query Service. Full graph power: multi-hop traversals, aggregations, subqueries, OPTIONAL, FILTER, UNION, BIND. Standard Wikidata prefixes (wd:, wdt:, p:, ps:, pq:, wikibase:, bd:) are auto-injected. The wikibase:label SERVICE is also auto-injected when language is set and the query includes ?<var>Label variables — so you can use ?itemLabel without writing the boilerplate. Hard server timeout is 60s; use LIMIT to keep queries fast. Bindings use the SPARQL 1.1 JSON format: each value is { type, value, "xml:lang"? }. Use wikidata_get_labels to humanize QID results from this tool.
