Common questions

Is Oura Ring (read-only) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 20 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Oura Ring MCP Server (read-only)

Ask Claude, Cursor, VS Code or any MCP client about your Oura Ring readiness, sleep, HRV, activity, stress and heart rate, without giving it any way to change your data.

*"How did I sleep last night, and why is my readiness only 64?"*

*"Compare my HRV and lowest heart rate over the last 30 days."*

*"Show me last night's sleep stages and heart-rate curve."*

*"Does my readiness drop after days I tagged alcohol?"*

(Run the one-time auth step before or after installing.)

Why this server

Read-only, enforced. Oura's API has no write endpoints for your data, and this client goes further: it can only send GET, refuses any URL outside /v2/usercollection/, never touches the webhook API, and every tool carries readOnlyHint: true. Tests fail the build otherwise.
Answers whole questions in one call. get_daily_overview returns a day's readiness, sleep, naps, activity, stress, resilience, SpO2, workouts and tags together. get_trends returns a day table plus averages and readiness zones over up to 90 days.
Model-friendly output. Compact JSON with hours, minutes, km and local times instead of seconds and meters; hypnograms as stage segments; heart rate aggregated into buckets. Pass raw: true for Oura's original objects.
Degrades gracefully. If you untick a data type on Oura's consent page, combined tools list it under unavailable instead of failing.
Your tokens stay on your machine. Your own Oura API application, OAuth with PKCE, a 0600 token file, and safe handling of Oura's single-use refresh tokens. No third-party servers, no telemetry.
Try it without an account. OURA_SANDBOX=1 serves Oura's public sample data.

Quick start

You need Node.js 20.11+ and an Oura account. (Oura retired personal access tokens in December 2025, so OAuth is the only way in.)

1. Create an Oura API application (2 minutes)

Open cloud.ouraring.com/oauth/applications and create a new application.
Set the Redirect URI to http://localhost:8787/callback.
Copy the Client ID and Client Secret.

Applications work for up to 10 users without Oura's approval, which is plenty for personal use.

2. Connect your Oura account

npx -y @royreznik/oura-ring-mcp auth

Paste your Client ID and Client Secret when asked (the secret isn't echoed). Your browser opens Oura's consent page; leave every data type ticked and approve. Tokens are saved to ~/.config/oura-ring-mcp/tokens.json and refreshed automatically from then on.

(For scripts, set OURA_CLIENT_ID and OURA_CLIENT_SECRET instead of answering the prompts.)

3. Add it to your MCP client

Claude Code

As a plugin (adds the server plus an /oura:auth skill that walks you through connecting):

/plugin marketplace add royreznik/oura-ring-mcp

/plugin install oura@oura-ring-mcp

Or just the MCP server:

claude mcp add oura --scope user -- npx -y @royreznik/oura-ring-mcp

Claude Desktop, Cursor, Windsurf

Add to the client's MCP config (Claude Desktop: Settings → Developer → Edit Config; Cursor: ~/.cursor/mcp.json; Windsurf: ~/.codeium/windsurf/mcp_config.json):

"mcpServers": { "oura": { "command": "npx", "args": ["-y", "@royreznik/oura-ring-mcp"] } } }

For Claude Desktop you can also install the .mcpb bundle from the latest release.

VS Code (GitHub Copilot)

.vscode/mcp.json (or your user mcp.json):

"servers": { "oura": { "type": "stdio", "command": "npx", "args": ["-y", "@royreznik/oura-ring-mcp"] } } }

</details>

OpenAI Codex CLI

~/.codex/config.toml:

[mcp_servers.oura]

command = "npx" args = ["-y", "@royreznik/oura-ring-mcp"]

</details>

Docker

Run auth on the host first, then mount the token directory:

docker build -t oura-ring-mcp https://github.com/royreznik/oura-ring-mcp.git

docker run -i --rm -v ~/.config/oura-ring-mcp:/home/node/.config/oura-ring-mcp oura-ring-mcp

</details>

Then ask: *"Give me my Oura overview for today."*

Try it without an account

claude mcp add oura-sandbox --env OURA_SANDBOX=1 -- npx -y @royreznik/oura-ring-mcp

Sandbox mode serves Oura's public sample data. No auth step, no personal data.

Configuration

Variable	Default	Purpose
`OURA_CLIENT_ID`	from token file	Your app's client ID (`auth` asks if unset)
`OURA_CLIENT_SECRET`	from token file	Your app's client secret (`auth` asks, without echoing, if unset)
`OURA_REDIRECT_URI`	`http://localhost:8787/callback`	Must exactly match a redirect URI registered on your app
`OURA_TOKEN_PATH`	`~/.config/oura-ring-mcp/tokens.json`	Where credentials are stored. Must be absolute (`~/` is expanded). Honours `XDG_CONFIG_HOME`.
`OURA_SANDBOX`	unset	`1` serves Oura's public sample data instead of your account

oura-ring-mcp            Start the MCP server on stdio (what your MCP client runs)

oura-ring-mcp auth Connect your Oura account (opens your browser) oura-ring-mcp status Check the stored connection oura-ring-mcp logout Delete the locally stored tokens oura-ring-mcp --version

"Today" is computed in your computer's timezone, which should match the timezone your Oura app uses.

Privacy and security

oura-ring-mcp talks only to api.ouraring.com (plus your browser visiting cloud.ouraring.com during auth). No telemetry, no intermediary server.
Tokens and your client secret live in one file only your user can read (0600). They are never logged or returned by tools.
Your MCP client sends tool results to its language model. Health data you ask about is shared with that model provider under its terms.
To disconnect, run oura-ring-mcp logout. To revoke access completely, delete the application at cloud.ouraring.com/oauth/applications or revoke it in your Oura account.

Details: PRIVACY.md, SECURITY.md.

How authentication works

OAuth 2 authorization-code flow with PKCE (S256) and a random state, captured by a loopback-only callback server.
Oura refresh tokens are single-use. oura-ring-mcp refreshes shortly before expiry (and on a 401), one refresh at a time, under a lock file so several clients on one machine (e.g. Claude Desktop and Claude Code) never refresh at once, and writes new tokens atomically. If a write fails, the new tokens stay in memory so a full disk can't log you out.
Rate limits (429, honouring Retry-After), server errors, timeouts (30s) and network errors are retried with backoff. Cancelling a request in your client stops its Oura calls.

Troubleshooting

Symptom	Fix
Oura shows a redirect URI error	The app's redirect URI must match `OURA_REDIRECT_URI` exactly, including `http://`, port and `/callback`.
`Port 8787 is in use`	Register another URI on your app (e.g. `http://localhost:9876/callback`) and run `auth` with `OURA_REDIRECT_URI` set to it.
`Not connected to Oura`	Run `auth`. If your client runs as a different user or `HOME`, set `OURA_TOKEN_PATH` in the client config.
`Oura rejected the refresh token`	Run `auth` again (app secret rotated, access revoked, or the token file was copied to another machine).
A data type appears under `unavailable` (403)	It was unticked on Oura's consent page, or needs an active Oura membership. Run `auth` again and allow it.
`426` error	Update the Oura app on your phone and open it so it syncs.
Today's data is missing	Oura only has data after the ring syncs through the Oura app. Open the app, then ask again.

Development

npm install

npm test # unit, MCP integration, end-to-end and packaging tests (no network) npm run smoke:sandbox # every tool against Oura's live sandbox API npm run smoke:live # every tool against your account (after auth); prints only counts npm run inspect # MCP Inspector

See CONTRIBUTING.md. The one hard rule: oura-ring-mcp stays read-only.
