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

Tool

What it returns

get_daily_health_summary(date?)

Normalized daily metrics + 7/30-day baselines (Oura now; Withings reserved).

get_oura_trends(days?, endDate?)

Daily time-series + latest/7-day/30-day summaries for key Oura metrics.

oura_connection_check()

Confirms the server can reach Oura and which data collections are returning.

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