About FamilySearch
FamilySearch is an MCP server published by the GitHub account ianderso. Genealogical research on FamilySearch: historical places, indexed records, page images, the tree.
It runs on your own machine: your AI client starts it from the PyPI package familysearch-mcp at version 1.4.0.
It asks for one secret: FS_ACCESS_TOKEN. Give it a key with the least access that still works.
Version 1.4.0 was published on 11 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for

FS_CLIENT_ID | No | No | Your registered application's client id, reported by auth_status. |
