# Fitbit MCP MCP > Fitbit analyzes deep health metrics, letting your AI agent pull data on active zone minutes, blood glucose levels, and sleep quality. You can manage fitness goals, create food logs, or analyze heart rate trends without opening the mobile app. It gives you raw numbers—like daily summaries of steps, calories, and weight changes—directly to your conversation. ## Overview - **Category:** data-analytics - **Price:** Free - **Tags:** fitness-tracking, health-data, activity-logs, wearables, wellness ## Description This MCP connects your Fitbit account directly to any AI agent for deep health analysis through natural conversation. Instead of digging through complex dashboards or exporting CSVs, you just ask the question. You can pull time series data on everything from heart rate variability (HRV) to blood glucose spikes, and even manage daily logs like creating a food entry or adjusting your weight goal. If you need access to this kind of diverse, granular health reporting, check out Vinkius, our catalog for managing all kinds of external APIs. It’s about getting insights from the raw data—like understanding why your Active Zone Minutes dipped last week—without needing a developer to build a custom report. Your agent handles the complexity; you get the answer. ## Tools ### create_activity_goal Sets a new goal for your general physical activity level. ### create_activity_log Adds a record of an activity you completed at a specific time and location. ### create_alarm Sets a reminder alarm on your device for a future time. ### create_food_log Records the food you ate and the approximate calories it contained. ### create_sleep_log Manually adds a record of your sleep duration and quality for a given night. ### create_subscription Creates or updates details about an ongoing subscription service. ### create_water_log Records the amount of water you drank throughout the day. ### create_weight_log Adds a new measurement of your body weight to your records. ### delete_activity_log Removes an incorrect or outdated entry from your activity history. ### delete_alarm Deletes a scheduled alarm or reminder you no longer need. ### delete_sleep_log Removes an incorrect sleep log entry from your records. ### delete_subscription Deletes a subscription record that is no longer active. ### delete_weight_log Removes an incorrect or outdated weight measurement from your history. ### get_activity_intraday Retrieves a breakdown of all activities performed within a single day. ### get_activity_log_list Gets a list summary of every activity log entry you've recorded. ### get_activity_tcx Accesses the raw, detailed technical files for specific workout sessions. ### get_alarms Retrieves a list of all currently active or scheduled alarms. ### get_azm_by_date Gets the total minutes spent in your Active Zone on a specific day. ### get_azm_by_interval Calculates Active Zone Minutes data across an entire date range. ### get_badges Fetches a list of fitness achievements or badges you have earned. ### get_blood_glucose Retrieves recorded blood glucose readings across specified time periods. ### get_body_goals Shows your current fitness targets, like desired weight or body fat percentage. ### get_breathing_rate_by_date Gets a summary of your breathing rate measurements for a specific day. ### get_breathing_rate_by_interval Retrieves breathing rate data across an extended time frame. ### get_core_temperature Gets the recorded core body temperature summary for a given date. ### get_daily_activity_summary Provides a high-level overview of your total daily steps, distance, and calories burned. ### get_devices Lists all the connected Fitbit devices linked to your account. ### get_ecg_log_list Gets a list of recorded electrocardiogram (ECG) measurements. ### get_food_log Retrieves all previously logged meals and the associated nutritional data. ### get_friends_leaderboard Shows a ranked list of your friends' fitness achievements against each other. ### get_friends Lists your connected Fitbit friends for comparison or leaderboard viewing. ### get_heart_rate_by_date Provides the heart rate data recorded for every hour of a specific day. ### get_heart_rate_by_interval Gets detailed heart rate metrics across a flexible date range. ### get_heart_rate_intraday Retrieves the minute-by-minute heart rate data recorded throughout a day. ### get_hrv_by_date Gets a summary of your Heart Rate Variability (HRV) for a given date. ### get_hrv_by_interval Retrieves HRV data across an extended time frame to track trends. ### get_irn_alerts Fetches a list of alerts related to your Irregular Rhythm Notifications (IRN). ### get_irn_profile Retrieves specific profile information regarding irregular rhythm notifications. ### get_profile Shows your basic account details and personal metrics recorded on Fitbit. ### get_skin_temperature Gets a summary of temperature readings taken from your skin sensors for a specific date. ### get_sleep_log_by_date Retrieves the detailed sleep log data recorded specifically for one night. ### get_sleep_log_by_interval Gets a comprehensive view of sleep logs across an entire date range. ### get_spo2_by_date Provides your blood oxygen saturation (SpO2) summary for a specific day. ### get_spo2_by_interval Retrieves SpO2 data across multiple dates to show trends. ### get_subscription_list Shows a full list of all current and past subscriptions linked to the account. ### get_vo2_max Calculates your estimated maximal oxygen consumption (VO2 Max) for a specific date. ### get_water_log Retrieves all logged instances of water intake for the day. ### get_weight_log Displays all recorded measurements of your body weight over time. ### introspect_token Checks the validity and scope of your connection token to ensure secure data access. ### update_alarm Changes the time or details of an existing alarm reminder. ### update_profile Modifies personal profile information, such as height or age. ## Prompt Examples **Prompt:** ``` Show my activity summary for today. ``` **Response:** ``` I've retrieved your daily summary.

They ask their agent, and it runs `get_azm_by_interval` and compares the results across months, showing a clear improvement curve. ### Post-Illness Check-in A user recovering from an illness needs to monitor basic health. They ask for their `get_spo2_by_interval` and check the core temperature trend using `get_core_temperature`, giving them a quick, actionable report. ### Dietary Accountability Someone trying to lose weight needs to track everything. They use `create_weight_log` every morning and then feed the data back into their agent alongside entries from `get_food_log` for a holistic picture. ### Deep Performance Dive A dedicated amateur runner needs to analyze pacing. They ask the agent to pull `get_activity_tcx` data for three specific runs, allowing them to inspect minute-by-minute performance metrics that standard summaries ignore. ## Benefits - Stop guessing about your fitness. Use the `get_azm_by_date` tool to pull Active Zone Minutes history, telling you exactly when and how hard you were working on specific days. - Tracking complex health changes used to mean diving into separate apps. Now, get vital metrics like blood glucose or core temperature summaries using tools like `get_blood_glucose` directly through your agent. - Need a quick record? Instead of opening the app and manually logging everything, use `create_food_log` or `create_water_log` to quickly update your daily totals with minimal effort. - Managing goals is easier than it was. Use `get_body_goals` to see what you're working toward, then use `create_activity_goal` to set the next target—all in one chat session. - The raw data is available when you need it. If a summary isn't enough, run `get_activity_tcx` to get the underlying technical files for deep personal analysis. ## How It Works The bottom line is that it takes all those complex health dashboards and turns them into simple conversational data points. 1. Subscribe to this MCP and enter your Fitbit Personal Access Token. This connects the system to your health account. 2. Tell your AI agent what data you need, for example: 'What was my SpO2 summary last week?' 3. The agent uses the necessary tools to pull the raw metrics and presents a summarized answer in plain language. ## Frequently Asked Questions **How do I check my blood glucose levels with get_blood_glucose?** You prompt your agent and specify the time range. It then runs `get_blood_glucose` to retrieve the recorded measurements for you, showing trends over that period. **Can I use create_activity_goal to set a weight goal?** No. Use `create_activity_goal` for physical movement targets. For managing body weight goals, you need the `get_body_goals` tool or `create_weight_log`. **What is get_azm_by_date?** This tool retrieves your Active Zone Minutes for a specific day. It helps quantify how much of your activity kept your heart pumping hard, which is key to fitness progress. **How do I see my sleep data across months using get_sleep_log_by_interval?** You use `get_sleep_log_by_interval` and specify the start and end dates. This gives you a comprehensive view of your rest patterns over an entire period. **Can I delete old records using delete_weight_log?** Yes, if you entered a weight measurement by mistake, running `delete_weight_log` removes that entry from your history so your data stays clean. **What should I do if my OAuth credentials expire before running get_profile?** You must re-authenticate with Fitbit through your client's developer tools. The MCP will prompt you to refresh the token when it detects an expired or invalid Personal Access Token (PAT). Always ensure your client handles token expiration gracefully for continuous use. **What date format does get_heart_rate_by_interval require for custom ranges?** It requires a standard ISO 8601 string for both the start and end dates. For example, 'YYYY-MM-DDTHH:MM:SSZ'. Using this precise format ensures your agent pulls data for the exact time window you need. **Are there rate limits when fetching a large set of logs using get_activity_log_list?** Yes, standard API usage applies. If you query too many entries in quick succession, your agent will receive an HTTP 429 error. You should implement pagination or add a small delay between calls to avoid rate limiting. **Can I check my Active Zone Minutes for a specific date range?** Yes. You can use the `get_azm_by_interval` tool by providing a start and end date to see your heart rate intensity trends over that period. **Is it possible to log a workout manually through the AI?** Absolutely. Use the `create_activity_log` tool. You just need to provide the activity details like ID, start time, and duration in the JSON body. **Can I monitor my weight and body fat goals?** Yes, the `get_body_goals` tool allows you to retrieve your current configured goals for either 'weight' or 'fat' to keep track of your progress.
