What is the FamilySearch API MCP Server?
Empower your AI agent to orchestrate your entire genealogical research and ancestry auditing workflow with the FamilySearch API, the world's largest platform for family history. By connecting FamilySearch to your agent, you transform complex ancestor searches into a natural conversation. Your agent can instantly retrieve person details, audit pedigree charts, and query historical record collections without you ever touching a genealogy portal. Whether you are building your family tree or conducting deep-dive historical audits, your agent acts as a real-time genealogical consultant, ensuring your data is always verified and precise.
What you can do
- Person Auditing — Search for millions of persons in the FamilySearch global tree and retrieve detailed metadata, including lifespans and birth/death places.
- Pedigree Oversight — Audit the ancestry charts for specific individuals to maintain a clear view of lineage distribution and scale.
- Memories Discovery — Retrieve photos, stories, and documents associated with specific persons to identify relevant assets instantly.
- Record Intelligence — List available historical record collections to understand the organizational reach of global archives.
- Metadata Intelligence — Retrieve unique identifiers and display names for any genealogical record to assist in deep-dive classification.
How it works
- Subscribe to this server
- Enter your FamilySearch Access Token
- Start managing your ancestry intelligence through Claude, Cursor, or any MCP-compatible client
Who is this for?
- Genealogists & Historians — monitor ancestry data and retrieve official metadata straight from your workflow.
- Family Researchers — verify person details and audit lineage patterns without manual searching.
- Librarians & Archivists — perform rapid audits of historical collections and identify relevant records through natural language.
