Findings
- MCP Registry discoverability is now table stakes: at least three alternatives also
publish
mcpName identities.
- The leading portability trade-off remains local-first/no-infrastructure
operation versus richer remote hosting, caching, or relay features.
- Current best practice is to document security controls, test/verification
commands, provenance or SBOM metadata, and the exact transport/auth model.
This project provides the first two and supports both local stdio and
authenticated Streamable HTTP; it does not claim to be a security audit.
Published 0.6.1 strengths
- 14 domain and analytical tools, 4 ambient resources, and 5 prompts in one
standalone package.
- No database, relay service, or framework runtime dependency; only the MCP SDK
and Zod are required.
- Published to npm and the official MCP Registry, with documented OAuth,
token refresh, retries, caching, HTTP hardening, and Inspector verification.
The table above is the historical August 30 snapshot, so its 14-tool count is intentional.
Version 0.7.0 adds two tools; its scope and evidence are in the
September feature scan.
Evidence and reproducibility: package names, versions, publish dates,
dependency counts, descriptions, and mcpName values come from the npm Registry
search and package manifests. Feature notes were checked against each package's
published metadata/README where available. Re-run the scan with:

🎥 Video Walkthrough
Watch a detailed walkthrough of setting up and using whoop-ai-mcp with Claude Desktop:

Covers: creating a WHOOP Developer App, configuring Claude Desktop, OAuth authentication, and querying your health data through natural conversation.
Prerequisites
- A WHOOP account with an active membership
- A WHOOP Developer App — create one at developer.whoop.com
- Set the redirect URI to
http://localhost:3000/callback
- Node.js >= 20
Get a WHOOP
Don't have a WHOOP yet? Here's how to get started:
Quickstart (MCP Registry)
This server is published on the official MCP Registry. MCP clients that support the registry can discover and install it automatically:
Server name: io.github.shashankswe2020-ux/whoop
You can also browse it via the registry API:
curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.shashankswe2020-ux/whoop"
Quickstart (Claude Desktop)
Add this to your Claude Desktop configuration file:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"whoop": {
"command": "npx",
"args": ["whoop-ai-mcp"],
"env": {
"WHOOP_CLIENT_ID": "your_client_id",
"WHOOP_CLIENT_SECRET": "your_client_secret"
}
}
}
}
Replace your_client_id and your_client_secret with the credentials from your WHOOP Developer App.
On first launch, a browser window will open for you to authorize access to your WHOOP data. After authorizing, tokens are cached locally and refresh automatically.
Then ask Claude something like:
"How am I doing today?"
"Show me my sleep data from the last 3 days"
"What workouts did I do this month?"
"Is my HRV trending up or down?"
"Give me a weekly health summary"
"Show me my recovery calendar for last 2 weeks"

Installation
Via npx (recommended)
No installation needed — Claude Desktop runs it automatically with the config above.
Global install
npm install -g whoop-ai-mcp
From source
git clone https://github.com/shashankswe2020-ux/whoop-mcp.git
cd whoop-mcp
npm install
npm run build
Setup wizard (whoop-ai-mcp setup)
For a guided installation that writes the Claude Desktop config (or prints the
registration command for Claude Code, Codex, or GitHub Copilot) and verifies
your WHOOP credentials in one go:
Flags:
--client=claude-desktop (default) writes/merges claude_desktop_config.json
with an automatic .bak backup.
--client=claude-code prints the equivalent claude mcp add command.
--client=codex prints the equivalent codex mcp add command (registers the
server in ~/.codex/config.toml).
--client=copilot prints the equivalent code --add-mcp command for GitHub
Copilot in VS Code.
--verify runs the OAuth flow end-to-end and fetches your profile to confirm
everything is wired correctly before exiting.
--client-id / --client-secret skip the interactive prompts (useful for
scripts; secrets entered interactively are masked).
If WHOOP_CLIENT_ID and WHOOP_CLIENT_SECRET are already exported in your
shell, the wizard uses them automatically — no prompts. Combine with
--verify to do a one-shot config-correctness check:
WHOOP_CLIENT_ID=... WHOOP_CLIENT_SECRET=... npx whoop-ai-mcp setup --verify
If the Claude Desktop config file already contains a whoop MCP entry from
a previous setup, the wizard short-circuits — it reads the existing
credentials, prints Existing whoop entry found in <path>, and either
verifies them (with --verify) or exits without rewriting the file. To
overwrite an existing entry, pass explicit --client-id / --client-secret
flags.
Precedence: --client-id / --client-secret flags > existing claude-desktop
config > WHOOP_CLIENT_ID / WHOOP_CLIENT_SECRET env vars > interactive
prompts.

metric | string | Yes | One of: recovery, hrv, rhr, sleep_duration, sleep_performance, strain. |
days | number | No | Number of days to analyze (7–90). Default: 30. |
get_today
Get today's complete health snapshot — recovery score, last night's sleep, current strain, and last workout in one call. Perfect for "how am I doing today?" questions.
Parameters: None
Returns: Recovery score with zone, sleep breakdown (hours, stages, performance), current strain, last workout (sport + strain), and a human-readable summary.
Recovery is returned only when it matches the current local cycle and primary sleep.
Pending or invalid primary sleep never falls back to an older recovery. Missing optional
sleep percentages are null, not zero. data_quality distinguishes missing, pending,
stale, unscored, calibrating, invalid and failed sources; cache status and fetch time
remain unknown when the client cannot establish them.
For compatibility, sleep.total_hours remains time in bed. Use time_in_bed_hours
or asleep_hours explicitly; summaries now use scored asleep stages. The latest
workout includes occurred_at and recording percentage and may be historical.
get_baselines
Returns personal distributions for HRV, resting heart rate, respiratory rate,
asleep hours and recovery score. baseline_days is an integer from 14 to 180
(default 30). Each band includes mean, median, standard deviation, percentiles,
sample size and the latest observation's midrank percentile.
The latest observation and current local day are excluded from each baseline.
Calibrating, unscored, invalid and unjoinable observations are excluded. A metric
needs 14 historical points after exclusions; otherwise its band is null with an
insufficient-data status. Constant distributions are labeled explicitly.
get_sleep_debt
Analyzes scored main sleeps using days (3-90, default 14) and optional start
(ISO or a supported relative expression). With start, the window extends forward
for days calendar days, clamped to evaluation time. Resolved bounds are returned.
total_debt_hours sums observed nightly deficits. Need excludes WHOOP's accumulated
debt component and preserves the signed nap adjustment; achieved sleep is light +
slow-wave + REM. standing_debt_hours is the latest WHOOP debt value, separately
dated, not the deficit sum. Missing nights are not zero-sleep nights; fewer than
three usable nights returns null aggregates. Circular local-clock statistics describe
consistency and heuristic social jetlag, not clinical diagnoses or recovery forecasts.
Analytics paginate up to 500 records per source and report upstream truncation.
Sleep-debt calculations use all selected records but echo at most 30 nights, with
a separate output_capped flag. Both tools include a statistical/medical disclaimer.
get_calendar
Get a day-by-day grid of recovery, sleep, and strain for a date range. Perfect for weekly/monthly overviews.
Parameters:
| Parameter | Type | Required | Description |
|---|
days | number | No | Number of days to show (1–90). Default: 7. |
start | string | No | Start date — ISO 8601 or relative expression ("last 14 days", "this month"). Defaults to N days ago. |
Returns: Per-day grid with recovery score + zone (green/yellow/red), sleep hours, sleep performance, and strain. Includes period averages.
Structured Results And Privacy
All tools advertise outputSchema and return validated structuredContent alongside
equivalent JSON text for older clients. Provider bodies and internal error details
are not returned in tool or resource errors.
Set WHOOP_MCP_PRIVACY_MODE=aggregate in the server process environment to expose
only get_weekly_summary, compare_periods, get_trend, get_baselines, and
get_sleep_debt. Per-record arrays, latest observations, standing debt, identity
fields and exact activity timestamps are omitted. Period bounds are date-only.
Raw resources and all five existing prompts are unavailable in this mode because
their workflows require raw tools/resources. Tool arguments cannot override the policy.
The default is standard, retaining all 16 tools, four resources and five prompts.
The standard-mode resource and prompt lists later in this README do not apply to
aggregate mode. To enable aggregation in a client configuration, add
"WHOOP_MCP_PRIVACY_MODE": "aggregate" to the server's existing env object.
Restart and reconnect after changing the process policy. Aggregate mode minimizes
disclosure; it is not anonymization, does not erase previously shared data, and
still sends health aggregates to the assistant provider.
get_today and the two new analytics tools use recorded offsets for local-day
attribution. Existing calendar and weekly-summary grouping remains UTC for compatibility.
An offset is not a timezone database and cannot reconstruct within-sleep DST changes.
Local Diagnostics
For a local build:
npm ci --ignore-scripts
npm run build
node dist/index.js doctor --json
With 0.7.0 installed, use whoop-ai-mcp doctor or
whoop-ai-mcp doctor --json directly. The command is not present in 0.6.1.
Checks runtime, configuration presence, privacy/transport settings and token-file
metadata without reading token contents, calling WHOOP, launching OAuth or writing
files. Exit codes: 0 = locally ready, 1 = remediation needed, 2 = invalid arguments.
Token validity and granted scopes remain unknown; setup --verify is the explicit
live check. POSIX private permissions are checked; Windows ACL privacy is not verified.
Supported Date Expressions
All collection tools and get_calendar accept natural language date expressions (case-insensitive):
| Expression | Example Result |
|---|
"today" | Today's UTC day boundaries |
"yesterday" | Yesterday's UTC day boundaries |
"last N days" (1–365) | N days back from today |
"last N weeks" (1–52) | N×7 days back from today |
"last N months" (1–12) | N calendar months back |
"this week" | Monday to today |
"last week" | Previous Monday–Sunday |
"this month" | 1st of month to today |
"last month" | Full previous month |
"this quarter" | Quarter start (Jan/Apr/Jul/Oct) to today |
"last quarter" | Full previous quarter |
"last year" | Jan 1–Dec 31 of previous year |
"YYYY-MM" (e.g., "2026-05") | Full calendar month |
| ISO 8601 | Pass-through (e.g., "2026-03-15T00:00:00Z") |
Resources
MCP Resources provide ambient health context — AI assistants can read your current health state without explicit tool calls.
| Resource URI | Description | Cache TTL |
|---|
whoop://v2/user/recovery/latest | Most recent recovery score, HRV, RHR | 5 min |
whoop://v2/user/sleep/latest | Most recent sleep record | 5 min |
whoop://v2/user/cycle/latest | Current physiological cycle (strain) | 2 min |
whoop://v2/user/profile | User profile (name, email) | 1 hr |
Privacy: Resources expose the same data available through tools — they simply make it accessible as ambient context. No additional WHOOP scopes are required. Data is cached in-memory with short TTLs and invalidated on token refresh.
To disable resources: set WHOOP_MCP_DISABLE_RESOURCES=1.
Caching
Read requests can be served from a shared in-memory cache (LRU + TTL) to cut
redundant WHOOP API calls and improve latency. The same cache backs both MCP
resources and tools such as get_today, so a warm cache answers repeat queries
without hitting the API.
| Data | TTL |
|---|
| Profile | 1 hr |
| Recovery, Sleep | 5 min |
| Cycle | 2 min |
| Collections (date-range queries) | Uncached |
- Cache keys are normalized by request path with sorted query params; no tokens are ever part of a cache key.
- Concurrent identical requests are de-duplicated (single in-flight fetch — stampede prevention).
- The entire cache is cleared on token refresh.
Write Operations
The server is read-only today — WHOOP does not currently expose public write
endpoints, so no write tools are registered. The codebase ships a
future-ready write-safety pattern (withPreview()) so that mutations, if WHOOP
adds them, follow a safe two-phase flow:
- Preview (
confirm: false) — returns a WritePreview describing exactly
what would change, plus a generated idempotency_key. Nothing is written.
- Confirm (
confirm: true) — executes the write and returns a
WriteReceipt carrying the same idempotency_key, so retried confirms never
create duplicate records.
This gives an AI assistant a built-in "show me before you do it" checkpoint and
makes retries safe by construction. See src/tools/write-safety.ts.
Prompts
Pre-built conversation starters that guide you into useful health queries:
| Prompt | Description |
|---|
weekly_health_review | Comprehensive review of recovery, sleep, and workouts (accepts optional days arg) |
sleep_analysis | Analyze recent sleep patterns and quality |
recovery_trend | How is recovery trending? HRV, RHR, recovery score analysis |
workout_recap | Summarize recent workouts, strain, and training load |
health_check | Quick health status using cached resource data |
Authentication
whoop-ai-mcp uses OAuth2 Authorization Code flow with PKCE:
- First run: A browser window opens for you to authorize with WHOOP
- Token caching: Access and refresh tokens are saved to
~/.whoop-mcp/tokens.json
- Auto-refresh: When the access token expires, it's automatically refreshed using the stored refresh token
- Re-authentication: If the refresh token expires, you'll be prompted to authorize again
Token files are stored with 0600 permissions (user-only read/write).
Troubleshooting
"Missing required environment variable: WHOOP_CLIENT_ID"
Your WHOOP credentials aren't set. Add them to your Claude Desktop config or set them as environment variables. See Configuration.
"Network error: Unable to reach the WHOOP API"
Check your internet connection. The WHOOP API must be reachable at https://api.prod.whoop.com.
"WHOOP API returned 429"
You've hit the rate limit. The server retries automatically with exponential backoff (up to 3 attempts). If this persists, reduce the frequency of your requests.
"WHOOP API returned 401"
Your access token has expired. The server attempts an automatic refresh. If that fails, delete ~/.whoop-mcp/tokens.json and restart to re-authenticate:
rm ~/.whoop-mcp/tokens.json
Browser doesn't open during authentication
If the browser doesn't open automatically, check the terminal output for the authorization URL and open it manually.
Testing with MCP Inspector
You can interactively test the server using the MCP Inspector — a browser-based tool for exploring and invoking MCP tools.
WHOOP_CLIENT_ID=your_client_id \
WHOOP_CLIENT_SECRET=your_client_secret \
WHOOP_REDIRECT_URI=http://localhost:3000/callback \
npx @modelcontextprotocol/inspector node dist/index.js
Then open http://localhost:6274 in your browser. The Inspector connects to the server, lists all available tools, and lets you invoke them with custom parameters.

Testing get_profile tool in MCP Inspector:

Deployment (Docker + Cloud Hosting)
The HTTP transport (MCP_TRANSPORT=http) makes this server suitable for remote
hosting so that web/mobile MCP clients (e.g. claude.ai connectors) can connect
to your personal WHOOP data over the network. A production-ready
Dockerfile is included.
Security warning. When running over HTTP you are exposing your WHOOP data
behind a single bearer token. Use a strong random MCP_AUTH_TOKEN
(openssl rand -hex 32), only deploy behind TLS, restrict
MCP_ALLOWED_ORIGINS, and treat the host as a personal-use deployment — not
a multi-tenant service.
Image characteristics
- Multi-stage build on
node:22-alpine (compressed pull size ~58 MB;
uncompressed ~258 MB — the floor is set by the Node.js runtime itself).
- Runs as the unprivileged built-in
node user (UID 1000).
tini as PID 1 for clean signal forwarding (graceful shutdown).
- Health check uses Node's native
fetch against /health — no curl/wget
baked into the image.
- All configuration is supplied at runtime via env vars; no secrets are baked
into image layers.

In your generated fly.toml, make sure the HTTP service points at port 3000
and that force_https = true is set under [[http_service]]. Fly handles
TLS termination, so MCP_TRUST_PROXY=1 is required for accurate client IPs
in logs and rate-limit decisions.
Railway
Railway auto-detects the Dockerfile.
- Create a new project from this GitHub repo (or
railway up from a clone).
- In Variables, add
MCP_AUTH_TOKEN, WHOOP_CLIENT_ID,
WHOOP_CLIENT_SECRET, and MCP_TRUST_PROXY=1.
- Under Settings → Networking, generate a public domain. Railway
terminates TLS for you.
- Deploy. Health check path:
/health.
The image is a stock OCI artifact and runs anywhere Docker does — Render, Cloud
Run, Kubernetes, Hetzner, etc. The only platform-specific knob is
MCP_TRUST_PROXY=1 whenever you sit behind a TLS-terminating proxy.
Connecting from claude.ai (OAuth 2.1 connector)
Claude Desktop and Claude Code can use the static MCP_AUTH_TOKEN bearer
directly. The claude.ai web/mobile clients expect an OAuth 2.1 connector
with PKCE — set the three env vars below and the server mounts the connector
automatically on the same port as /mcp:
fly secrets set \
MCP_CONNECTOR_PASSWORD="$(openssl rand -base64 24)" \
PUBLIC_URL="https://whoop-mcp-<your-suffix>.fly.dev" \
ALLOWED_REDIRECT_URIS="https://claude.ai/api/mcp/auth_callback"
MCP_CONNECTOR_PASSWORD (≥12 chars) — the human-facing password you'll type
into the claude.ai connector dialog. Treat it like any other shared secret.
PUBLIC_URL — the public https:// origin claude.ai will reach. Used as
the OAuth issuer (e.g. https://example.com → metadata at
/.well-known/oauth-authorization-server).
ALLOWED_REDIRECT_URIS — comma-separated exact-match allowlist. For
claude.ai the value is https://claude.ai/api/mcp/auth_callback.
- Optional:
MCP_JWT_SECRET overrides the JWT signing key (defaults to an
HKDF derivation from MCP_AUTH_TOKEN); MCP_OAUTH_CLIENT_ID overrides the
advertised client id (default whoop-mcp-connector).
In claude.ai → Settings → Connectors → Add custom connector, point it at
PUBLIC_URL/mcp and supply MCP_CONNECTOR_PASSWORD when prompted.

git push origin main vX.Y.Z
- The Release workflow automatically creates a GitHub Release with notes extracted from the changelog
- The npm publish workflow automatically publishes the new version to npm
Changelog
See CHANGELOG.md for a full list of changes in each release.
The analytical tools — get_weekly_summary, get_trend, and
compare_periods — return pre-computed statistical summaries derived from
your underlying recovery / sleep / cycle / workout records. No new health
data is exposed beyond what the per-record collection tools already return
(get_recovery_collection, get_sleep_collection, etc.), but the
aggregated form is more concentrated and easier to scan over time. In
particular, the anomalies array returned by get_trend flags days that
deviate from your personal baseline — such days may correlate with
illness, injury, travel, or lifestyle changes.
If you connect this MCP server to a remote AI assistant (rather than a
local one), be aware that those summaries will be sent to that assistant
in the same way any other tool result is. All data continues to flow only
between the WHOOP API, this MCP server running on your machine, and the
assistant you explicitly invoke — there is no third-party telemetry.
