Use it in your assistant · Claude Code
Your family, in Claude Code.
Add AncestralFire to Claude Code once, sign in with your AncestralFire account, and ask about your family there. It's the same family and the same answers as on our site, and answers in Claude Code don't use up your free answers on the site.

In Claude Code
- In a terminal, add it once for every folder:
claude mcp add --transport http --scope user ancestralfire https://mcp.ancestral-fire.com/mcp - Start Claude Code and type
/mcp, choose ancestralfire, and sign in with your AncestralFire account. - Ask: "What's in my family tree?"
AncestralFire works with FamilySearch Family Tree, the free shared tree. When you connect it, you sign in on the FamilySearch website, and we never see your password. Disconnecting in Settings deletes the token we hold.
Before anything is added to FamilySearch Family Tree, the shared tree, you see exactly what will be written and press Approve, with your reason. The assistant can't approve it for you. In Claude on the web and in Claude Desktop, you approve it in a card in the conversation. Where an assistant can't show the card, it gives you a link that opens the same change on ancestral-fire.com, where you approve it signed in to your account.
Any assistant that connects to remote MCP servers can use the same address: it's a hosted server over HTTPS, and you sign in with your AncestralFire account. Nothing runs on your computer.
Your family is on our site too: ancestral-fire.com. Stuck? Write to us.
