# genealogy-mcp — find your family history with any AI assistant

<!-- mcp-name: io.github.igormel81/genealogy-mcp -->

An [MCP](https://modelcontextprotocol.io) server that turns Claude, ChatGPT, Cursor or any MCP-capable assistant into a
careful genealogist. It knows **where** the records of your ancestors are (114 archives and databases across Russia and
the former USSR, Europe, the British Isles, the USA and Latin America), **how** to search them (name variants,
transliterations, old spelling, the Julian calendar), and **when a find really is your person** — so the assistant gives
you working links and a plan instead of confident guesses.

Built from years of real research for an open family archive ([igoruan.ru/gene](https://igoruan.ru/gene), engine:
[gene_archive](https://github.com/igormel81/gene_archive)): parish registers, revision lists, WWI and WWII databases,
repression files, emigration records — and every trap we fell into along the way.

## What you can ask

> *My great-grandfather Ivan Kolodin was born about 1885 near Bogoroditsk, Tula province. Where do I look?*

The assistant makes a plan for Russia 1880–1945, reads the record guides, builds the name forms (Колодин / Колодина /
Колодинъ / Kolodin / Kołodin…), gives you search links for FamilySearch, the Internet Archive full text and the
Russian war databases, tells you which archive holds the parish registers and drafts the request.

> *Is this baptism record the same Ivan? It says «Іоаннъ, father Петръ, 1887, Сынково».*

`check_match` compares fact by fact with name variants and age tolerance: two independent facts beyond the name →
confirmed; one → probable; a contradiction → find a third document.

> *What is my grandmother's cousin's daughter to me? И как это по-русски?*

`kinship` → «троюродная сестра… / first cousin once removed» — in Russian, English and Romanian, with the expected DNA share.

> *Check my tree.* (a GEDCOM from Ancestry, MyHeritage, Gramps, Geni…)

`audit_tree` finds the impossible (born after the mother's death, a mother aged 10, death before birth), possible
duplicates and gaps — a to-do list for the next search.

> *The register says he was born «на Покров» 1885, the year is written ҂аѡ҃пе.*

`cyrillic_numerals` reads the year (1885), `feast_date` gives 1 October (Julian) = 13 October 1885.

> *We share 230 cM with a match on MyHeritage. Who could she be?*

`dna_match`: second cousin, first cousin twice removed, half first cousin… — and why only documents can decide.

> *Where are the parish registers of Volhynia governorate now?*

`where_are_records`: the state archives of Zhytomyr (the consistory), Rivne and Volyn — borders moved, so it is not
always the archive of today's region.

> *Remember what we found, and continue next week.*

A research project on your computer: people, sources with full citations, open leads and a log of every search —
including "nothing found" — so nobody searches the same place twice. GEDCOM in and out.

## Why use it

| Without it | With genealogy-mcp |
|---|---|
| The assistant names two or three famous websites | 114 sources chosen by country, years and kind of record, each with "how to search it well" |
| Searches one spelling | Spelling variants, pre-1918 orthography, male/female forms, 9 transliteration systems, given-name equivalents (Иван = Іоаннъ = Jan = Johann = Juan) |
| Invented or broken URLs | Ready search links built from tested URL templates; a weekly job checks every site |
| "This is probably your ancestor" | An explicit evidence rule: a namesake is not a relative |
| Dates taken at face value | Julian ↔ Gregorian, birth years from ages with realistic drift, dates normalised to GEDCOM |
| Generic advice | Record guides: parish registers, confession lists, revision lists, household books, WWI/WWII, repression files, passenger lists, censuses, European civil registration, Latin American records |
| You write to archives from scratch | Request drafts for Russian ZAGS, state, military and FSB archives, and for any archive in English, Spanish or Portuguese |
| It forgets everything between chats | A research project that remembers people, sources, leads and every search |
| It cannot read old numbers and dates | Church Slavonic numerals, church feasts, Julian, Hebrew and French Republican calendars |
| "Search FamilySearch for your name" | Live search in the Internet Archive full text, WikiTree, Open Archives and Wikidata place history |
| DNA matches are a mystery | Shared cM → the relationships it fits |

Everything runs on your computer. The server goes online only when the assistant runs a live search
(`search_online`, `place_history`), and then sends that query to that one site.

## Install

**Claude Desktop, one click:** download `genealogy-mcp-<version>.mcpb` from the
[latest release](https://github.com/igormel81/genealogy-mcp/releases/latest) and open it — Claude Desktop installs
it and asks where to keep your research projects.

For the other ways you need [uv](https://docs.astral.sh/uv/getting-started/installation/) (it fetches Python and the
package by itself).

**Claude Desktop, by hand** — Settings → Developer → Edit Config, add:

```json
{
  "mcpServers": {
    "genealogy": {
      "command": "uvx",
      "args": ["genealogy-mcp"]
    }
  }
}
```

**Claude Code:**

```sh
claude mcp add genealogy -- uvx genealogy-mcp
```

**Cursor** (`~/.cursor/mcp.json`), **Windsurf**, **Cline** — the same `mcpServers` block as for Claude Desktop.
**VS Code** (`.vscode/mcp.json`): `{"servers": {"genealogy": {"command": "uvx", "args": [ …same… ]}}}`.

**Docker:** `docker build -t genealogy-mcp .` then `docker run -i --rm genealogy-mcp` (stdio) or
`docker run --rm -p 8000:8000 genealogy-mcp --http --host 0.0.0.0` (HTTP at `/mcp`).

**Clients that connect over HTTP** (ChatGPT connectors, remote agents): run
`genealogy-mcp --http --host 0.0.0.0 --port 8000` behind HTTPS and add `https://your-host/mcp`.
In HTTP mode `audit_tree` takes the GEDCOM text only, never a file path.

The package is on [PyPI](https://pypi.org/project/genealogy-mcp/) and in the [official MCP Registry](https://registry.modelcontextprotocol.io) (`io.github.igormel81/genealogy-mcp`): `uvx genealogy-mcp` installs and runs it.

**Prompts:** start research, check a find, transcribe a record, write to an archive.

## Privacy and honesty

- The server sends nothing anywhere by itself. A live search (`search_online`, `place_history`) sends the query — names,
  years, place — to the one site searched. Research projects are files on your computer
  (`~/Documents/genealogy-mcp` or `GENEALOGY_MCP_HOME`); on a shared HTTP server they are switched off.
- The assistant you use is a separate service with its own privacy policy — think before pasting details about living
  people.
- Letters are drafts: you check and send them.
- The rules the assistant gets: cite the original, keep conflicting versions, mark guesses as "probably", never link a
  namesake without evidence.

## Benchmark

`evals/tasks.json` holds 32 questions with checkable answers: dates by church feasts, Julian, Hebrew and Republican
calendars, Cyrillic numerals, Daitch–Mokotoff, DNA, kinship, old terms, archives of historical provinces, evidence
checks, record history. `evals/check_tools.py` runs in CI and checks that the tools answer all of them correctly.
`evals/run.py` asks a Claude model the same questions without the server and with it and scores both
(needs an API key; it costs money, so it is run by hand: Actions → Benchmark).
