AncestralFire

Use it in your assistant · Claude

Your family, in Claude.

Add AncestralFire to Claude 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 don't use up your free answers on the site.

In Claude

  1. Open Customize → Connectors (claude.ai/customize/connectors).
  2. Click + Add, then Add custom connector.
  3. Name it AncestralFire, paste the address above, and click Continue.
  4. Keep the sign-in settings Claude suggests, click Continue, then Add.
  5. Click Connect and sign in with your AncestralFire account.
  6. On the same page, under Tool permissions, set Read-only tools to Always allow, so Claude can look things up in your tree without asking each time. Anything that would change your tree still waits for you to press Approve.

Then turn it on in a conversation from the + button, under Connectors. It works on every Claude plan; the free plan allows one custom connector. On a Team or Enterprise plan, an Owner adds it for the organization first, under Organization settings → Connectors.

FamilySearch

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.

Nothing changes without you

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.

Other assistants

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.
