About this source

The Wikimedia Foundation’s own MCP service for Wikidata: hybrid keyword and semantic search for items and properties, statement lookup, class hierarchies and SPARQL. A join layer for reconciling names, places and identifiers, not a substitute for primary records.

Good to know

  • Official server. Run by the organisation behind the database, so results come straight from the source.
  • Cited, checkable answers. Results are treated as retrieved material and cited with the source’s own identifiers, so you can open every record the answer relied on.
  • Your files stay private. Only the search the assistant writes for your question is sent to Wikidata.
