What it can do

What Claude Code can do with it

Plans written back: Yes. Claude Code reads your training and writes the sessions it plans back to Memory.fit, asking before each change unless you allowed it.
Where it runs: Your terminal, on a computer.
Good to know: Claude Code adds Memory.fit with one command in your terminal and signs in from /mcp. It reads your Polar training and Nightly Recharge there, and before it changes your plan it asks for your yes; once you allow it, it shows on Plan in the Memory.fit app.

Ask Claude Code about your Polar data

“Read my Nightly Recharge for the last two weeks and tell me which nights I recovered worst.”

Uses:get_daily_metricsget_sleep

“Compare my training load this month with last month.”

Claude CodeExample

About 14% higher: 520 a week on average this month, against 456 last month. Your biggest week, 598, held two long runs.

From the video. Answers depend on your data.

Uses:get_training_load

“How did my sleep change on the nights after my hard sessions?”

Uses:get_sleepget_workouts

“Move tomorrow's threshold run if my Nightly Recharge is poor, and tell me why.”

Claude CodeExample

Your Nightly Recharge was poor last night, ANS charge −5.8, so I moved Thursday's threshold run to Saturday. Thursday is now an easy 40 min run.
