## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `whoop_body_measurement`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The user's body measurements (height in meters, weight in kilograms, max heart rate). WHOOP REST: GET /v2/user/measurement/body. Scope: read:body_measurement.
```

## Only reads (9)

Looks things up and changes nothing. Claude Code: allow.

### `whoop_get_cycle`

- The name "whoop_get_cycle" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a single physiological cycle by its id (strain, kilojoules, average/max heart rate, start/end). WHOOP REST: GET /v2/cycle/{cycleId}. Scope: read:cycles.
```

### `whoop_get_cycle_recovery`

- The name "whoop_get_cycle_recovery" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the recovery scored for a specific cycle (recovery %, resting heart rate, HRV RMSSD, SpO2 %, skin temperature). WHOOP REST: GET /v2/cycle/{cycleId}/recovery. Scope: read:recovery.
```

### `whoop_get_profile`

- The name "whoop_get_profile" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The current user's basic WHOOP profile (user id, email, first name, last name). WHOOP REST: GET /v2/user/profile/basic. Scope: read:profile.
```

### `whoop_get_sleep`

- The name "whoop_get_sleep" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a single sleep activity by its id (stage summary, sleep needed, respiratory rate, sleep performance %, start/end). WHOOP REST: GET /v2/activity/sleep/{sleepId}. Scope: read:sleep.
```

### `whoop_get_workout`

- The name "whoop_get_workout" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a single workout by its id (sport, strain, average/max heart rate, distance, zone durations, start/end). WHOOP REST: GET /v2/activity/workout/{workoutId}. Scope: read:workout.
```

### `whoop_list_cycles`

- The name "whoop_list_cycles" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's physiological cycles (a WHOOP 'day', ~24h anchored to sleep), most recent first. Each cycle carries a score with day strain, kilojoules burned, and average/max heart rate. Paginated (limit/nextToken) and filterable by created-time window (start/end). WHOOP REST: GET /v2/cycle. Scope: read:cycles.
```

### `whoop_list_recoveries`

- The name "whoop_list_recoveries" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's recoveries, most recent first. Each recovery scores how ready the body is (recovery %, resting heart rate, HRV RMSSD, SpO2 %, skin temperature) and links to its cycle and sleep. Paginated (limit/nextToken) and filterable by created-time window (start/end). WHOOP REST: GET /v2/recovery. Scope: read:recovery.
```

### `whoop_list_sleep`

- The name "whoop_list_sleep" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's sleep activities, most recent first. Each carries a score with sleep-stage summary, sleep needed, respiratory rate, and sleep performance %. Paginated (limit/nextToken) and filterable by created-time window (start/end). WHOOP REST: GET /v2/activity/sleep. Scope: read:sleep.
```

### `whoop_list_workouts`

- The name "whoop_list_workouts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's workouts, most recent first. Each carries a score with strain, average/max heart rate, distance (meters), and per-heart-rate-zone durations. Paginated (limit/nextToken) and filterable by created-time window (start/end). WHOOP REST: GET /v2/activity/workout. Scope: read:workout.
```
