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.

Deploy (one click)

Clicking the button copies this repo into your GitHub, creates the KV namespaces and Durable Object automatically, and deploys the Worker.

After deploying — set your secrets

In the Cloudflare dashboard: Workers & Pages → your Worker → Settings → Variables and Secrets, add these as type Secret:

Secret	Value
LOGIN_PASSWORD	A strong password. You'll type this once when connecting Claude.
OURA_TOKEN	Your Oura Personal Access Token (read-only).

(Optional: TIMEZONE, defaults to America/Los_Angeles.)

Connect Claude

Claude → Settings → Connectors → Add custom connector → Name: Fernanda Health, URL: https://<your-worker>.<subdomain>.workers.dev/mcp. Claude will open the login page; enter your LOGIN_PASSWORD to authorize.
