## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-03.

- **Endpoint Security**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1057 tokens (~105/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (10)

### `oura_get_personal_info` (~74 tokens)

Get personal info

Fetch the wearer's profile — age, weight, height, biological sex and email. Oura: GET /v2/usercollection/personal_info.

Input parameters:

- `sandbox` (boolean): Read Oura's synthetic sandbox data instead of the wearer's real data. Use this to learn a response shape without a ring.

### `oura_list_documents` (~228 tokens)

List documents from a collection

List documents from one Oura collection over a date range. This is the main read: pick `collection` for what you want — daily_sleep and sleep for sleep, daily_readiness for recovery, daily_activity for movement, daily_stress and daily_resilience for load, workout and session for exercise, daily_spo2, daily_cardiovascular_age and vO2_max for cardiovascular measures, tag and enhanced_tag for the wearer's own annotations, rest_mode_period and ring_configuration for device state. Oura: GET /v2/usercollection/{collection}.

Input parameters:

- `collection` (string, required): Which document collection to read.
- `end_date` (string): End of the range, YYYY-MM-DD.
- `next_token` (string): Cursor from the previous page's next_token. Omit for the first page.
- `sandbox` (boolean): Read Oura's synthetic sandbox data instead of the wearer's real data. Use this to learn a response shape without a ring.
- `start_date` (string): Start of the range, YYYY-MM-DD. Defaults to a recent window.

### `oura_get_document` (~101 tokens)

Get one document

Fetch a single document by id from one collection. Ids come from oura_list_documents. Oura: GET /v2/usercollection/{collection}/{document_id}.

Input parameters:

- `collection` (string, required): Which collection the document belongs to.
- `document_id` (string, required): The document's id.
- `sandbox` (boolean): Read Oura's synthetic sandbox data instead of the wearer's real data. Use this to learn a response shape without a ring.

### `oura_get_heartrate` (~180 tokens)

Get heart-rate samples

Fetch individual heart-rate samples over a DATETIME range. This collection is sampled continuously, so it uses start_datetime/end_datetime rather than dates, and can return a great many points — narrow the window or pass latest. Oura: GET /v2/usercollection/heartrate.

Input parameters:

- `end_datetime` (string): ISO-8601 end.
- `latest` (boolean): Return only the most recent sample.
- `next_token` (string): Cursor from the previous page's next_token. Omit for the first page.
- `sandbox` (boolean): Read Oura's synthetic sandbox data instead of the wearer's real data. Use this to learn a response shape without a ring.
- `start_datetime` (string): ISO-8601 start, e.g. 2026-08-01T00:00:00Z.

### `oura_get_ring_battery_level` (~137 tokens)

Get ring battery level

Fetch ring battery readings over a DATETIME range, or just the latest. Oura: GET /v2/usercollection/ring_battery_level.

Input parameters:

- `end_datetime` (string): ISO-8601 end.
- `latest` (boolean): Return only the most recent reading.
- `next_token` (string): Cursor from the previous page's next_token. Omit for the first page.
- `sandbox` (boolean): Read Oura's synthetic sandbox data instead of the wearer's real data. Use this to learn a response shape without a ring.
- `start_datetime` (string): ISO-8601 start.

### `oura_list_webhook_subscriptions` (~34 tokens)

List webhook subscriptions

List the webhook subscriptions registered for the application. Oura: GET /v2/webhook/subscription.

### `oura_get_webhook_subscription` (~53 tokens)

Get one webhook subscription

Fetch a single webhook subscription with its callback URL, event type and expiry. Oura: GET /v2/webhook/subscription/{id}.

Input parameters:

- `subscription_id` (string, required): The subscription's id.

### `oura_create_webhook_subscription` (~135 tokens)

Create a webhook subscription

Register a webhook so Oura notifies your callback URL when data changes. Oura verifies the URL before activating it, and the subscription EXPIRES — renew it with oura_renew_webhook_subscription. Oura: POST /v2/webhook/subscription.

Input parameters:

- `callback_url` (string, required): The HTTPS URL Oura should call.
- `data_type` (string, required): Which collection to watch, e.g. daily_sleep or workout.
- `event_type` (string, required): Which change to be notified about.
- `verification_token` (string, required): A secret Oura echoes back so you can verify the callback.

### `oura_renew_webhook_subscription` (~68 tokens)

Renew a webhook subscription

Extend a webhook subscription's expiry. Oura subscriptions lapse if not renewed, so this is the tool that keeps a live integration alive. Oura: PUT /v2/webhook/subscription/renew/{id}.

Input parameters:

- `subscription_id` (string, required): The subscription to renew.

### `oura_delete_webhook_subscription` (~47 tokens)

Delete a webhook subscription

Remove a webhook subscription. Notifications stop immediately. Oura: DELETE /v2/webhook/subscription/{id}.

Input parameters:

- `subscription_id` (string, required): The subscription to delete.

io.usefulapi/oura exposes 10 tools: oura_get_personal_info, oura_list_documents, oura_get_document, oura_get_heartrate, oura_get_ring_battery_level, and 5 more. Their descriptions and schemas cost roughly 1,057 tokens of context every time the server is loaded.

### Does the io.usefulapi/oura MCP server require authentication?

Yes. io.usefulapi/oura asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
