npm wellness-cycle-coachstdioMITupdated 10d ago
Menstrual cycle coach MCP for AI agents — now with PCOS-aware mode. Built so AI finally serves the 50% of users agents have ignored — without ever storing cycle data.
What can you do with wellness cycle coach?
⚡ One-command install — pick your runtime:
- Delx Wellness for Hermes:
npx -y delx-wellness-hermes setup- Delx Wellness for OpenClaw:
npx -y delx-wellness-openclaw setup
HTTP (v2 stateless)
Default is stdio. Optional Streamable HTTP — no session id, JSON responses, loopback only:
npx -y wellness-cycle-coach --http
# GET http://127.0.0.1:3000/health
# POST http://127.0.0.1:3000/mcp (sessionless)
Env: WELLNESS_CYCLE_COACH_HOST, WELLNESS_CYCLE_COACH_PORT, WELLNESS_CYCLE_COACH_TRANSPORT=http.
Overview
Pass in period start dates (from any source — Apple Health Cycle, Garmin women's health, Fitbit female health, or direct user input) and get back the user's current phase plus phase-aware recommendations for nutrition, training, and hydration. Stateless — the MCP itself never persists cycle data. Supports PCOS-aware mode via the cycle_irregular flag (v0.3.3) — accepts cycles 21-90 days, caps confidence at 'low', and returns a luteal_extended placeholder when standard 14-day-luteal math no longer applies.
Try It In 60 Seconds
npx -y wellness-cycle-coach doctor
# Or use the MCP directly via your client:
# {
# "mcpServers": {
# "wellness-cycle-coach": {
# "command": "npx",
# "args": ["-y", "wellness-cycle-coach"]
# }
# }
# }
Then in your agent:
{
"name": "cycle_full_report",
"arguments": {
"history": [
{ "start_date": "2026-04-01" },
{ "start_date": "2026-04-29" }
]
}
}
Returns current phase + nutrition emphasize/moderate/avoid + training style/intensity + hydration target + next-period estimate.

The 4-phase model
| Phase | When | Energy | Nutrition emphasis | Training |
|---|---|---|---|---|
| menstrual | days 1 → period end (~5) | Lower | Iron + magnesium + omega-3 | Restorative (yoga, walking, mobility) |
| follicular | post-period → ovulation - 2 | Rising / peak | Complex carbs + lean protein + fermented foods | Build (strength, sprints, new skills) |
| ovulatory | ovulation ± 1 day | Peak | Antioxidants + zinc | Peak (PRs, plyometrics) |
| luteal | ovulation + 2 → next period | Falling | B vitamins + magnesium + complex carbs | Endurance + technique |
Why stateless?
Menstrual cycle data is medical-record sensitive. The strongest privacy guarantee is to never store it. Other apps (Flo, Clue) live by hoarding cycle data on their servers; this MCP refuses to participate. The agent passes data in, the coach returns guidance, the data evaporates.

Privacy
- ✅ Stateless for cycle data — period dates are never persisted; they stay in process memory for the duration of the call and evaporate.
- ✅ Opt-in local preferences — the
cycle_profile_*tools can persist non-secret wellness preferences (name, goals, devices, training/nutrition context) to~/.delx-wellness/profile.json, but only when the user explicitly asks (cycle_profile_updaterequiresexplicit_user_intent: true). Secrets (tokens, API keys, biomarkers) are rejected at write time. - ✅ Offline-capable — pure-function computation. No outbound calls.
- ✅ Tool-arg-only cycle data — the agent passes period history in via the MCP request and it stays in process memory.
Run wellness-cycle-coach doctor to inspect.
What this is NOT
- Not medical advice or diagnosis.
- Not a fertility tracker or contraception aid (consult a clinician).
- Not a replacement for talking to a healthcare provider about painful, abnormal, or absent periods.
- PCOS / irregular cycles supported via
cycle_irregular: true(v0.3.3), but this is NOT a substitute for clinical care — see clinician for fertility, contraception, or symptom-management decisions. - Not specialized for perimenopause or post-pill (yet — see CONTRIBUTING.md).
Roadmap
- v0.2 — adapters for apple-health-mcp / garminmcp / fitbitmcp so agents can pull period history with one MCP call.
- v0.3 — symptom logging surface + symptom-aware guidance adjustments (cramps → magnesium emphasis, mood drop → B-vitamin emphasis).
- v0.4 — non-English locale support starting with pt-BR.

Skill or MCP
Same package, two doors. MCP registers tools on stdio/HTTP. The skill can drive the same tools through the CLI when the client has no MCP:
npx -y wellness-cycle-coach call cycle_connection_status --json '{}'
Copy skill/SKILL.md into your agent skills dir.
