The Athlete Data MCP for Training Analysis and Planning

Features

• Training Plan Management

  View, modify, and create structured workouts for cycling, running, and swimming with precise intervals and training zones

• Activity Analysis

  Access detailed metrics from your cycling rides (power analysis, heart rate, heart rate variability), running workouts (pace analysis, running power), and swimming sessions, plus durability on every ride and run: how power or pace held up as the work piled on, and how that compares to your own trend. Computed analytics (normalized power, intensity factor, time-in-zone, pacing and fade) are calculated server-side for any activity, and activities from other sports like strength training, skiing, or hiking are available too

• Performance Predictions

  ML-based race time predictions for running and cycling events, with fitness forecasting to track your improvement

• Recovery Tracking

  Monitor HRV (heart rate variability), resting heart rate, and sport-specific recovery metrics to optimize your training readiness

• Nutrition Requirements

  Get personalized daily calorie and macronutrient recommendations based on your training load, including protein, carbohydrates, and fat targets

• Training Zone Management

  Update and view pace zones for running, power zones for cycling, and swimming pace targets

• Workout Scheduling

  Move workouts between days, skip sessions, and track plan progress with automatic sync to all connected platforms (Garmin, TrainingPeaks, Intervals.icu, etc.)

• Race Goal Management

  Track primary and secondary race objectives for running, cycling, or triathlon events

• Strength & Other Workouts

  Create custom strength training, yoga, hiking, cross-country skiing, and other non-endurance activities with free-form workout descriptions

• Activity Data Quality

  Correct how an activity was detected (indoor, virtual, erg mode) and exclude activities with bad sensor data from your power and pace curves, HRV analysis, durability, and race predictions

Real Sessions

Based on live MCP tool calls from the AI Endurance founder's account, lightly edited for clarity. The numbers are real rather than mock data. AI Endurance analyzes training data imported from your connected platforms (Garmin, Wahoo, TrainingPeaks, Intervals.icu and more). It is an AI Endurance MCP server for your athlete data, not an official MCP server of those platforms.

Did I fade on my long ride?

You: "How did Saturday's long ride go, did I fade?"
AI: [Fetches the ride and its durability analysis]
    Saturday was 99 km in 3:13 moving time, 180 W average power,
    859 m of climbing, external stress score 259.

    You did fade, and about as much as your own trend predicts:
    fresh you held 303 W for 5 minutes, but after 2,000 kJ of work
    the best 5-minute effort was down to 213 W (-30%). Heart rate,
    DFA alpha 1 and respiration all sat inside your usual band at
    matched work. Verdict: typical durability, no red flag.

    One more thing: your HRV was clean enough (1.2% artifacts) to
    estimate an aerobic threshold of ~234 W from this ride alone.

Am I recovered enough to go hard?

You: "Am I ready for a hard session today?"
AI: [Fetches the recovery model]
    Yes. Overall recovery is 97/100 this morning: rMSSD 89 ms,
    resting heart rate 40 bpm, and ride-specific muscle recovery
    at 97.

    For context: Saturday's big ride (stress score 259) pulled
    recovery down to 84 on Sunday, driven by your DFA alpha 1,
    and you were back near 100 by Monday. Green light.

Move a workout, then change your mind

You: "Move next Wednesday's tempo run to Monday"
AI: [Moves the workout and confirms the change]
    Done. Tempo Run (2 x 8 min at 4:21-4:38 /km) moved from
    Wednesday Sep 16 to Monday Sep 14. The change syncs to your
    connected platforms automatically.

You: "Actually, put it back"
AI: [Moves it back and re-checks the plan]
    Moved back to Wednesday Sep 16. Your week is exactly as it
    was: every workout around it is unchanged.

What should I eat tomorrow?

You: "What should I eat tomorrow?"
AI: [Fetches the nutrition model and tomorrow's workouts]
    Tomorrow is a double day with a 34-minute strength endurance
    swim plus a 1:20 endurance ride, so the target is 3,820 kcal
    (range 3,438-4,202): 124 g protein, 592 g carbs, 106 g fat.

    Compare that to Friday, where a single 32-minute swim puts the
    target at 2,707 kcal and 383 g carbs. The carbs move with the
    training load; protein stays constant.

What exactly is my swim workout?

You: "Walk me through tomorrow's swim"
AI: [Fetches the planned workout with full structure]
    Strength Endurance Swim, 1,600 m, about 34 minutes:
    - Warm up 300 m at endurance pace (2:09-2:16 /100m)
    - Prep set 200 m stepping from tempo down to VO2max pace
    - Main set 1,000 m with pull buoy and paddles
    - Cool down 100 m easy

    Coaching note from the session: the paddles increase water
    pressure on your hands, so keep pressure on the paddle all the
    way through the stroke to build strength without losing form.

More Things You Can Ask

Beyond the transcripts above, the same tools answer and act on requests like these:

"Show me my workouts for this week"
"What was my average pace on runs this month?"
"Show me the power curve from my last ride"
"Compare my last 3 long runs"
"Yesterday's ride was on Zwift, not outdoors" (fixes the flags)
"My heart rate strap was dead - ignore its data for this run"
"Am I training enough in the Threshold zone?"
"What's my predicted time for my goal race?"
"Update my running threshold pace"
"Add a 2-hour hike for Saturday"
