Render minimalist family tree diagrams:

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

family-tree-maker.mnapoli.fr

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

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

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.

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.
