freddy

by reThrive Labs LLC

Overview

freddy connects the health apps and devices you already use to Claude. Once linked, Claude can answer questions about your sleep, recovery, training, daily activity and continuous metrics in any conversation, grounded in your own history rather than generic advice. Apple Health, Garmin, Oura, WHOOP, Polar, Withings, Suunto, Wahoo, Ultrahuman, Concept2, Hevy, Airthings, Health Connect and Intervals.icu are supported today, and new sources are added regularly. freddy brings them into one place, keeps your full history, and can return raw detail when you want it: per-exercise sets from a strength session, sleep-stage hypnograms, per-second workout samples, continuous glucose streams. Setup takes a couple of minutes. Sign in at freddy.coach, connect a source, then add the connector here. Your data stays yours. freddy reads each source with read-only credentials you grant, stores everything encrypted at rest, and never sells, shares or brokers it. freddy does not train models on your health data. You can disconnect a source, revoke access, export everything, or delete your account at any time.

Tools

accept_terms

ChatGPT

Record the user's acceptance of Freddy's current Terms of Service and Privacy Policy. ONLY call this tool AFTER the user has explicitly stated they agree to the updated terms — for example, after they have said 'I agree', 'accept', 'yes, accept the new terms', or similar. Do not call this tool automatically or on the user's behalf. If the user has not seen the policy summary yet, show them the gate message from the previous tool call's response (or fetch https://freddy.coach/terms) BEFORE asking for their consent. If the user is unsure or wants to read the full text, do not call this tool — point them at the dashboard URL or the public Terms/Privacy pages. If the user has explicitly agreed to BOTH the Terms/Privacy AND to Freddy collecting and processing their health data, also pass health_data: true. Otherwise omit health_data or pass false; the user will be prompted for the additional consent through the dashboard later.

connect_source

ChatGPT

Connect a wearable, ring, CGM, training platform, gym log, Apple Health, or Health Connect. Returns an interactive source picker plus a complete text fallback. OAuth approval and credentials always happen on freddy or the provider, never inside chat. When a health question triggered this tool, pass original_question so the card can restore it after the first sync.

connect_wearable

ChatGPT

Connect a data source (a wearable, ring, CGM, training platform, gym log, and so on). For OAuth providers (Polar, Oura, WHOOP, Withings, Dexcom, Intervals.icu, Suunto), the tool returns a URL the user opens to authorize. For API-key sources (Hevy, Lyfta, Runalyze, Airthings) and device sources (Apple Health, Health Connect), the tool returns instructions to finish connecting on the freddy dashboard or app, where any credential is entered on freddy and never passes through this chat.

connection_status

ChatGPT

Private MCP Apps connection-card helper. Models must never call this tool directly.

disconnect_source

ChatGPT

Disconnect a data source and wipe synced data for it. Confirm with the user before calling — this is destructive and the user must re-authorize to reconnect.

disconnect_wearable

ChatGPT

Disconnect a data source and wipe synced data for it. Confirm with the user before calling — this is destructive and the user must re-authorize to reconnect.

get_profile

ChatGPT

Return user profile information: name, connected data sources, plan tier, and the date range of available data.

list_metrics

ChatGPT

List health metrics available for this user. Returns metric names, units, date ranges, record counts, and data sources. Metrics flagged [raw available] carry a full JSON payload (per-exercise sets, hypnograms) that can be fetched via query_metrics with include_raw: true. Metrics flagged [raw-only — fetch with include_raw] are intra-day sample bundles (e.g. activity_HR_samples for Suunto); the data lives in the raw payload, not in numValue. For these, request include_raw to get the ts/v arrays. Daily aggregates of the same data are available as _avg/_min/_max/_total metrics. Lines may show "device: <name>" when a provider reports data from more than one device; pass that device to query_metrics to filter. When you present Garmin data to the user, attribute it as "Garmin [device model]" (or just "Garmin" when no device is shown), per Garmin's brand requirements.

query_metrics

ChatGPT

Fetch health data for specific metrics by name. Metric names are provider-specific and follow each provider's own field-name conventions (e.g. activity_* / wellness_* for Intervals.icu, polar_* for Polar, workout_* for Hevy, sleep_summary_* for Withings). They are NOT common English words. Always call list_metrics first in a session to discover the exact names available for this user — names that aren't in that list return zero rows. Returns scalar values grouped by date. When include_raw is true, also returns the full JSON payload for each record (per-exercise sets, hypnograms, intra-day sample arrays). Non-sample raw is capped at 50 records per request. For intra-workout sample metrics (names ending in _samples), include_raw returns a downsampled overview by default (tighter record cap — narrow the range if asked to); pass raw_resolution: "full" for every sample of a single workout, or sample_window: { from_sec, to_sec } to zoom a segment of a long workout at full resolution. Each sample row shows 'id: <…>' — pass that as source_id to select one of several same-day workouts for a full or windowed read. When you present Garmin data to the user, attribute it as "Garmin [device model]" (or just "Garmin" when no device is shown), per Garmin's brand requirements.

sync_provider

ChatGPT

Trigger an incremental sync for a connected provider. Returns immediately; the sync runs in the background. Use this if the user wants the latest data fetched right now (e.g. after a workout) instead of waiting for the daily sync.
