What MCP for Wikidata Does Not Do: No Editing, No User Data Changes

A good technical tool often earns trust not only by what it can do, but by what it refuses to do. That matters here. The open source project often described as MCP for Wikidata, and more specifically the Wikidata + Google Knowledge Graph MCP server and CLI, has a sharply bounded role. It helps AI agents and developers search Wikidata, read selected facts, and connect local records to likely Wikidata items with inspectable evidence. It does not try to be a publishing syst

Understanding Qualifiers in MCP for Wikidata Fact Retrieval

When people first work with Wikidata through an MCP server, they often focus on the headline fields: name, description, identifier, maybe a date or two. That gets you through a demo, but it does not get you very far in real retrieval work. The hard part usually starts when a fact is technically correct and still incomplete. A person held an office, but when exactly. A work has a title, but in which language. An organization has a location, but during what period. That is wh

How MCP for Wikidata Supports Evidence-Based Linking

Entity linking sounds deceptively simple until you have to do it at scale, under time pressure, and with records that were clearly assembled by different people in different decades. A title is abbreviated in one system, transliterated in another, and split across two fields in a third. Dates are partial. Names collide. Organizations rename themselves. A place can be both a municipality and a region depending on which catalog you inherited. That is where evidence matters

MCP for Google Knowledge Graph and Wikidata for Safer Entity Resolution

Entity resolution sounds tidy on paper. In practice, it is where otherwise sensible data projects go sideways. A local record says “Mercury.” Is that the planet, the element, the record label, the Roman god, or the newspaper someone abbreviated in a spreadsheet ten years ago? Once a system picks the wrong identity, everything downstream starts to look plausible and wrong at the same time. That is the dangerous kind of error, because it survives dashboards, QA passes, and ev

MCP for Google Knowledge Graph and Wikidata: A Practical Introduction

If you spend any time linking records, researching entities, or trying to keep an assistant grounded in structured data, you run into the same problem quickly: search is easy, resolution is hard. Finding ten plausible matches for a person, company, place, or work is not the same as identifying the right one, explaining why it is right, and knowing when the evidence is too thin to trust. That is why the recent open source project often described as MCP for Google Knowledg
