Render minimalist family tree diagrams:

Simple web app with PNG export
HTTP API
ChatGPT / Claude integration via MCP

family-tree-maker.mnapoli.fr

Usage

Web

Use the web UI to create a family tree diagram using the built-in form. The diagram is rendered live as you edit the form, and you can export it as PNG or SVG.

URL: family-tree-maker.mnapoli.fr

AI agents

Use the remote MCP server to render family trees directly from a conversation with Claude or ChatGPT.

Follow the instructions on this page: family-tree-maker.mnapoli.fr/mcp

API

Base URL: https://family-tree-maker.mnapoli.fr

POST /api/render — JSON tree → PNG
GET /api/tree.svg?d=<encoded> — SVG
GET /api/tree.png?d=<encoded> — PNG
POST /mcp — remote MCP server (Streamable HTTP, single tool render_family_tree)

More details on the API endpoints are available in the API documentation.

Development

Runs on Cloudflare Workers: SSR (Hono + React 19), a small HTTP API, and a remote MCP server so Claude / ChatGPT can render trees directly from a conversation.

Develop

npm install
npm run fonts   # download the Cormorant Garamond font once
npm run dev

Then open http://localhost:8787.

npm run build
npm run deploy
