WHOOP MCP

WHOOP says you are recovered.Recovered for what?

Kracey gets your WHOOP sleep, HRV and resting heart rate into Claude or ChatGPT, next to your training.

What reaches your assistant

Three readings, each against your own last 30 days.

Sleep

Your usual range

Last night, your seven-day average and the last 14 nights.

HRV

Your usual range

How far it sits from your own usual range.

Resting heart rate

Your usual range

The same, against your last 30 days.

Drawn to show the shape of the answer, not a real reading.

What does not come through

  • Your recovery score
  • Strain
  • Workouts logged in WHOOP
  • Respiration and SpO2

intervals.icu takes sleep, HRV and resting heart rate from WHOOP, not workouts, so your sessions come from your watch.

Ask about both at once

Your answers depend on your own data. More in the prompt library.

You: Using Kracey, my HRV has been low all week. Is that the hard sessions?

HRV against your usual range, next to the last two weeks of training.

You: Using Kracey, which of my last 14 nights came before my biggest sessions?

Sleep night by night, next to your session list.

You: Using Kracey, show last night's sleep, my HRV and my resting heart rate, each against my own usual range for the last 30 days, and my sleep for each of the last 14 nights.

Your recovery readings against your own normal.

Kracey or a WHOOP MCP server from GitHub?

A server from GitHub reads more of WHOOP. Kracey puts WHOOP next to your training.

Read against the plan

Your assistant puts your sleep next to your sessions. The Kracey coach, a paid subscription in Telegram, sets it against what comes next.

A brief when your sleep syncs

Last night's sleep, HRV and resting heart rate, then today's session.

A plan that moves

Say the week has changed and your coach reworks it in the chat.

No traffic lights

Your coach says what the night means for the session, in words.

14 free days, no card. They start when your coach can see your training.

Set it up in four steps

  1. 1

    Connect WHOOP to intervals.icu.

    Make a free account, open the WHOOP box in settings, pick your metrics and press Connect.

    Does your watch send HRV or sleep too? Tick only what you want from WHOOP, or it can overwrite your watch's readings.

  2. 2

    Connect your watch there too.

    It sends your sessions. Connect it to intervals.icu directly, not through Strava.

  3. 3

    Sign up at kracey.com/me.

    No subscription needed. Then link intervals.icu under Settings.

  4. 4

    Add Kracey to your assistant.

    Tick Heart and recovery data, or WHOOP's readings stay out.

Skip this if

You want your recovery score in the chat

It does not come through. WHOOP's API exposes it, so a server from GitHub should be able to.

A WHOOP is all you wear

With no sessions in intervals.icu, there is no training to compare your sleep with.

Your assistant is not on the list

Kracey connects to Claude, Claude Code and ChatGPT only.
