What the publisher says

From the GOV Historical Gazetteer repository's README, as published. We do not edit it. Read it on GitHub

gov-gazetteer-mcp

<!-- mcp-name: io.github.ianderso/gov-gazetteer-mcp -->

An MCP server for GOV, the Geschichtliches Orts-Verzeichnis: the historical gazetteer of the Verein für Computergenealogie (CompGen), with about 1.2 million places, mostly in Germany and the lands that were once German or Prussian. GOV dates everything it records about a place: its names, what kind of place it was, and every place that enclosed it, civil and ecclesiastical.

That makes it the tool for the question a genealogist asks of every German village: in the year of the event, which Kreis, province and state held it, and which parish and Standesamt kept its registers? A village in Posen was Prussian until 1919 and Polish after 1920; a Pomeranian one was German until 1945. A Kreis was renamed, an Amt dissolved, a parish merged. The server reads GOV's public web service and answers for one year at a time, and it gives the dated enclosures a genealogy program needs to build a place tree that is right for every date.

It works the way a careful genealogist does. A gazetteer entry is a finding aid, not evidence. GOV is edited by volunteers: a parish or Standesamt link says which register to look in, and the register's own heading confirms it. Every result credits GOV and CompGen and carries the address of each object's page on GOV, because that page is what gets cited.

Nothing here writes anywhere, and nothing here keeps a family tree. It sits well beside familysearch-mcp, whose place tools resolve a place by date but know no parishes or Standesämter, and us-places-mcp, its counterpart for American counties.

This is an independent project. It is not affiliated with, endorsed by, or supported by the Verein für Computergenealogie.

Tools

The server publishes six tools. All are read-only.

Setup

You need Python 3.11 or later and uv. There is no key to request.

uvx gov-gazetteer-mcp

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
