Fernanda Health — private health-data MCP server

A private, read-only Model Context Protocol server that lets Claude retrieve your own Oura Ring (and later Withings) health data for a daily check-in.

• Private & self-hosted on your own Cloudflare account.

• Read-only. It only reads your data; it can never change anything.

• Authenticated. Claude connects only after passing an OAuth login gated by a password you set. Nothing is exposed without authentication.

• No secrets in code. All tokens/passwords live as encrypted Cloudflare secrets.

What it exposes

The server only retrieves and normalizes data. All interpretation is done by Claude.
