oura-mcp-server

Local-first MCP server that connects AI agents to your Oura Ring readiness, sleep, activity and HRV data.

Unofficial project. Not affiliated with, endorsed by or supported by Ōura Health Oy. Oura is a trademark of its respective owner. Use this only with your own Oura account and in line with the Oura Cloud API terms.

Built by David Mosiah for people who use Claude, Cursor, Hermes, OpenClaw or other MCP-compatible agents to think about readiness, sleep and recovery — without copy-pasting numbers from the Oura app.

Part of Delx Wellness, a registry of local-first wellness MCP connectors.

Why this exists

Oura Ring produces some of the most refined personal health signals — readiness scores, sleep stages, HRV, daily activity, SpO2, body temperature trends. But it lives behind an OAuth API with per-scope authorization, and the data is split across multiple endpoints (daily readiness vs. detailed sleep periods vs. heart-rate streams).

This package handles the OAuth dance locally, normalizes responses across endpoints, and exposes Oura through the Model Context Protocol. Tokens never leave your machine. Privacy-mode defaults keep raw payloads opt-in.

Setup in 60 seconds

You'll need an Oura app (create one here) with redirect URI http://127.0.0.1:3000/callback.

npx -y oura-mcp-unofficial setup    # interactive: paste client id + secret
npx -y oura-mcp-unofficial auth     # opens browser, captures the OAuth code
npx -y oura-mcp-unofficial doctor   # verifies you're ready

Recommended scopes:

daily heartrate personal sleep workout spo2

Then add this to your MCP client config:

{
  "mcpServers": {
    "oura": {
      "command": "npx",
      "args": ["-y", "oura-mcp-unofficial"]
    }
  }
}

For Claude Desktop, run setup --client claude and the snippet is written for you.

Try it with your agent

Three things to ask first:

Use oura_connection_status to check setup, then run oura_daily_summary.
Give me a 5-line operating brief for today.

Call oura_weekly_summary with response_format=json. Identify my biggest
readiness/sleep bottleneck and give me a next-week plan.

Use the oura_daily_checkin prompt, focus=sleep.
Don't claim Oura can prove anything it can't.

Data availability

This package uses the official Oura Cloud API v2. When this README says raw, it means the upstream Oura JSON for a supported endpoint — not raw device sensor streams.

Data	Available	Notes
Daily readiness score + contributors	✓	Requires `daily` scope
Daily sleep score + sleep periods	✓	Requires `daily` and/or `sleep` scope
Sleep stages + timing	✓	When Oura returns scored sleep
Daily activity (steps, calories, MET)	✓	Requires `daily` scope
Heart-rate time series	✓	When ring/membership/scope expose it
HRV (overnight, via daily summaries)	✓	Surfaced through readiness contributors
SpO2 (daily averages during sleep)	✓	Requires `spo2` scope; supported devices
Workouts + sessions + tags	✓	Requires `workout`/`session`/`tag` scopes
Personal info (DOB, sex, height, weight)	✓	Requires `personal` scope
Continuous sensor telemetry	—	Not exposed by Oura Cloud API

Tools

Start with these:

oura_connection_status — verify local setup before calling Oura
oura_daily_summary — readiness, sleep, activity and SpO2 brief for today
oura_weekly_summary — scorecard, comparison vs prior week, next-week plan

Privacy & security

OAuth tokens are stored in ~/.oura-mcp/tokens.json with 0600 permissions and are never returned by tools.
The server never prints access or refresh tokens.
OURA_PRIVACY_MODE defaults to structured. Raw Oura JSON is opt-in via raw mode or per-call override.
Personal info (DOB, sex, height, weight) is only accessible when the user grants the personal scope.
The MCP client never sees access or refresh tokens.
This is not medical advice. The server exposes user-authorized data for personal AI workflows, not diagnosis or treatment.

Configuration

setup writes most of these into ~/.oura-mcp/config.json (0600). Manual env override is supported:

OURA_CLIENT_ID=…
OURA_CLIENT_SECRET=…
OURA_REDIRECT_URI=http://127.0.0.1:3000/callback

# Optional
OURA_SCOPES="daily heartrate personal sleep workout spo2"
OURA_PRIVACY_MODE=structured        # summary | structured | raw
OURA_CACHE=sqlite                   # optional read-through cache
OURA_TOKEN_PATH=~/.oura-mcp/tokens.json
OURA_CACHE_PATH=~/.oura-mcp/cache.sqlite

Hermes / remote setup

npx -y oura-mcp-unofficial setup --client hermes --no-auth
npx -y oura-mcp-unofficial auth                      # run locally if browser auth is needed
npx -y oura-mcp-unofficial doctor --client hermes
hermes mcp test oura

After Hermes config changes, use /reload-mcp or hermes mcp test oura. Don't restart the gateway for normal data access.

If browser OAuth has to happen on a different machine than Hermes, run auth locally and copy ~/.oura-mcp/tokens.json to the server with chmod 600.
