whoop-mcp-server

MCP server for the official Whoop API v2, written in Go. Exposes cycles, recovery, sleep, workouts, and profile data as MCP tools.

Tools

All tools return JSON. Record shapes are the unmodified Whoop API v2 objects, so every field the API exposes is available to the model.

Tool	Inputs	Returns
`get_profile`	—	Single object: `user_id`, `email`, `first_name`, `last_name`
`get_body_measurement`	—	Single object: `height_meter`, `weight_kilogram`, `max_heart_rate`
`get_cycles`	`start_date`, `end_date`, `limit` (all optional)	Array of cycle records — one per physiological day: `start`/`end`, `score_state`, and `score` with day `strain`, `kilojoule`, `average_heart_rate`, `max_heart_rate`
`get_latest_cycle`	—	Single cycle record (the current/most recent day)
`get_recoveries`	`start_date`, `end_date`, `limit` (all optional)	Array of recovery records — one per sleep: `cycle_id`, `sleep_id`, and `score` with `recovery_score` (0–100), `resting_heart_rate`, `hrv_rmssd_milli`, `spo2_percentage`, `skin_temp_celsius`
`get_recovery_for_cycle`	`cycle_id` (required)	Single recovery record for that cycle
`get_sleep`	`start_date`, `end_date`, `limit` (all optional)	Array of sleep records: `start`/`end`, `nap` flag, and `score` with per-stage durations (light/SWS/REM/awake, in ms), `respiratory_rate`, `sleep_performance_percentage`, `sleep_efficiency_percentage`, sleep-need breakdown
`get_workouts`	`start_date`, `end_date`, `limit` (all optional)	Array of workout records: `sport_name`, `start`/`end`, and `score` with workout `strain`, heart rates, `kilojoule`, `distance_meter`, `altitude_gain_meter`, time-in-zone durations (`zone_durations`, ms per HR zone)
`get_average_strain`	`days` (optional, default 7)	Computed aggregate: `{days, cycles_counted, average_strain}`
`check_auth_status`	—	`{authenticated: bool}` plus the profile on success or an `error` string on failure

Notes:

Dates are YYYY-MM-DD; end_date is inclusive (internally mapped to the start of the next day, per the API's exclusive end semantics).
Collections are date-descending (most recent first) and paginated transparently — the server follows next_token until limit records (default 25, max 100) are collected.
Scores are point-in-time per record, not time-series: one strain value per cycle, one recovery per sleep. For trends, fetch a range and let the model aggregate (or use get_average_strain for the built-in strain average).
A record's score_state can be SCORED, PENDING_SCORE, or UNSCORABLE — score is only present when SCORED.

Setup

1. Create a Whoop developer app

At developer.whoop.com, create an app with:

Redirect URI: http://localhost:8719/callback
Scopes: read:cycles, read:recovery, read:sleep, read:workout, read:profile, read:body_measurement, offline

Note the client ID and client secret.

2. Install

Homebrew:

brew install zayden16/tap/whoop-mcp-server

Or download a prebuilt binary from Releases, or:

go install github.com/Zayden16/whoop-mcp-server@latest

Or build from source:

go build -o whoop-mcp-server .

3. Authorize (one time)

server.ts

export WHOOP_CLIENT_ID=...
export WHOOP_CLIENT_SECRET=...
./whoop-mcp-server auth

Opens a browser for the OAuth flow; the token is saved to ~/Library/Application Support/whoop-mcp/token.json (macOS) and refreshed automatically thereafter (rotating refresh tokens).

4. Register with Claude Code

Terminal

claude mcp add whoop --scope user \
  -e WHOOP_CLIENT_ID=... \
  -e WHOOP_CLIENT_SECRET=... \
  -- /path/to/whoop-mcp-server

Or for Claude Desktop, in claude_desktop_config.json:

config.json

{
  "mcpServers": {
    "whoop": {
      "command": "/path/to/whoop-mcp-server",
      "env": {
        "WHOOP_CLIENT_ID": "...",
        "WHOOP_CLIENT_SECRET": "..."
      }
    }
  }
}

Example queries

"What's my recovery score today?"
"Show my sleep for the past week"
"What's my average strain over the last 7 days?"
