You don't gotta manually export files from the app anymore; you just talk to it, and it pulls all that raw fitness data for you. ### Daily Activity & Training Logs You need a rundown of what happened yesterday? Use `get_activity_by_date` to pull a summary of every metric recorded on one specific day. To see your overall activity totals, check out the list provided by `list_activities`. If you want a preview of raw numbers for review, run `list_activity_samples`. For deep dives into past workouts, `list_exercises` pulls up a roster of all training sessions logged in the last thirty days. You can then use `get_exercise` to grab detailed information on any specific session's routes or heart rate zones. ### Sleep and Recovery Status Figure out how recovered you are after a night's rest, and we got tools for that. Run `list_nightly_recharge` to check your recent recovery scores and Nightly Recharge status. To gauge your overall sleep quality and duration, use `list_sleep` for specific dates. You can also track when you were most alert during the night with `get_sleepwise_alertness`, or calculate your estimated optimal bedtime based on your circadian rhythm data using `get_sleepwise_circadian_bedtime`. ### Core Biometrics and Health Metrics You want specific health numbers? You can check for a continuous stream of heart rate samples over time with `get_continuous_heart_rate`, or calculate the overall training strain and recovery level using `get_cardio_load`. For basic physical stats, `get_physical_info` retrieves your static measurements like weight and maximum heart rate. Advanced readings include fetching the results of a wrist-based ECG test taken during sleep or activity via `get_biosensing_ecg`, and getting the latest body temperature data with `get_biosensing_body_temperature`. You can also pull the percentage of oxygen saturation (SpO2) recorded by your device using `get_biosensing_spo2`. ### Exporting Raw Data Files Don't want to stay locked into Polar’s ecosystem? When you get detailed exercise data, you can download it in industry-standard file formats. Use `get_exercise_fit` to pull all metrics for an exercise as a FIT file. For the geographic path of your run or ride, run `get_exercise_gpx`. If you need it in TCX format, call `get_exercise_tcx`. ### Account and Data Management Utilities Need to manage the data flow? You can check if any new or available Polar data is waiting for your account by running `get_notifications`. The system lets you see which webhooks are currently active with `get_webhooks`. If you need to set up a new automated data push notification, use `create_webhook`; conversely, you can delete one using `delete_webhook`, or toggle an existing webhook on with `activate_webhook` and off with `delete_webhook`. For account control, you can register a user after authorization via `register_user`, or completely remove a user's access permissions by running `delete_user`. Finally, basic identifying details about the linked account are available through `get_user`. ## Tools ### activate_webhook Turns on a webhook that was previously deactivated. ### create_webhook Sets up a new data push notification (webhook). ### delete_user Removes a user's account and revokes their access permissions. ### delete_webhook Deletes an existing data push notification (webhook). ### get_activity_by_date Retrieves a summary of all activity metrics recorded for one specific day. ### get_biosensing_body_temperature Gets the latest measured body temperature data from your wearable sensor. ### get_biosensing_ecg Fetches the results of a wrist-based ECG test taken during sleep or activity. ### get_biosensing_skin_temperature Retrieves measurements of your skin temperature, often used for tracking sleep quality. ### get_biosensing_spo2 Gets the percentage of oxygen saturation (SpO2) recorded by your device. ### get_cardio_load Calculates and retrieves data on training strain and recovery levels based on heart rate metrics. ### get_continuous_heart_rate Gathers a stream of continuous heart rate samples over time. ### get_exercise_fit Downloads all metrics for an exercise in the FIT file format. ### get_exercise_gpx Downloads the geographical path of an exercise in the GPX format. ### get_exercise_tcx Downloads all metrics for an exercise in the TCX file format. ### get_exercise Pulls detailed data for a specific exercise session, including routes and zones. ### get_notifications Checks if there is any new or available data waiting for any user registered with Polar. ### get_physical_info Retrieves your basic, static physical metrics like weight and maximum heart rate. ### get_sleepwise_alertness Gets data detailing when you were most alert during the night. ### get_sleepwise_circadian_bedtime Calculates and returns your estimated optimal bedtime based on your circadian rhythm data. ### get_user Retrieves basic, identifying information about the user linked to the account. ### get_webhooks Shows the current configuration status of all active webhooks for the account. ### list_activities Lists a summary list of your daily activity totals and metrics. ### list_activity_samples Provides samples or previews of raw activity data for review. ### list_exercises Fetches a list of all training sessions recorded within the last 30 days. ### list_nightly_recharge Lists your Nightly Recharge status and recovery scores for recent nights. ### list_sleep Retrieves the recorded sleep metrics, including duration and quality, for specific dates. ### register_user Register a user after authorization ## Prompt Examples **Prompt:** ``` List my training sessions from the last 30 days. ``` **Response:** ``` I've found 12 exercises in the last 30 days.

The agent runs `list_sleep` and correlates that output with `get_cardio_load`, giving a clear picture of if recovery is keeping up with training demands. ### Analyzing Sleep Disturbances An athlete notices strange heart rate dips. They prompt: 'Show me my sleep data for last night, including SpO2.' The agent runs `list_sleep` and `get_biosensing_spo2`, allowing the user to spot potential nighttime issues immediately. ### Comparing Training Efforts A data nerd wants to compare two running sessions. They ask: 'Give me the route for my October 5th run and the metrics for my last cycle.' The agent uses `get_exercise_gpx` for the first and `get_exercise` for the second, side-by-side. ### Calculating Performance Drift A coach needs to track if a client's recovery is slowing down. They ask: 'List my Nightly Recharge scores from the last four weeks.' The agent runs `list_nightly_recharge`, showing the trend in recovery status instantly. ## Benefits - See your full recovery picture instantly. Instead of digging through separate reports, you can query `list_nightly_recharge` and `list_sleep` together to understand if your sleep quality matches your recent training load. - Download data in any format. Need a specific GIS tool for mapping? Use `get_exercise_gpx`. Want to run it through a custom stats program? Grab the raw metrics using `get_exercise_fit` or `get_exercise_tcx`. - Analyze deep biometrics on demand. You don't need to wait for weekly reports; you can ask your agent to pull `get_biosensing_ecg` results alongside your heart rate data from `get_continuous_heart_rate` for immediate review. - Track consistency, not just mileage. Use `list_activities` and compare the step counts across months versus comparing total run distances via `list_exercises`. It gives you a complete picture of daily movement. - Get physical context fast. The `get_physical_info` tool provides your current weight and max heart rate right away, so you don't have to look up baseline metrics elsewhere. ## How It Works The bottom line is, you never have to log into Polar and click through pages again; you just ask your AI client for what you need. 1. Subscribe to the Polar Alternative server and provide your Polar Access Token. 2. Your AI client connects this token to the MCP Server's API endpoints. 3. You prompt your agent with a natural language request (e.g., 'What was my sleep score last night?') which triggers the necessary tools. ## Frequently Asked Questions **How do I check my training sessions using list_exercises?** The `list_exercises` tool pulls all your recorded workouts from the last 30 days.
