Best for
  • Endurance athletes (cycling, running, triathlon) seeking professional-level insights.
  • Users who prefer self-hosting to have full control over their data.
  • Athletes looking for AI guidance that considers a holistic view beyond just power numbers.
  • Hevy PRO users who want AI assistants to directly access their workout data
  • People who prefer using MCP clients like Claude, Cursor, Codex for fitness tracking
  • Anyone needing summaries and insights from their training data
Not for
  • Casual users who do not want to deal with technical setup.
  • Individuals who want a simple step counter without multiple platform data collection.
  • Users seeking advanced strength training plans for gym workouts, rather than endurance focus.
  • Users without a Hevy PRO subscription (API key required)
  • Users who want to use the server without an API key
  • Those needing delete workflows (Hevy API does not expose delete endpoints)
Required permissions
  • Access to user-authorized third-party fitness platforms (e.g., Strava, Whoop, Oura) to sync data.
  • Authentication via OAuth 2.0 to securely access user data.
  • Storage and processing of personal health and training data on a self-hosted server or cloud.
  • Requires HEVY_API_KEY environment variable for Hevy API authentication
  • Can create, update, and replace workouts, routines, folders, templates, and body measurements via tools
  • Read operations can fetch workouts, routines, folders, templates, history, and user info
Risks and side effects
  • Privacy risk: Aggregating health data requires access to multiple third-party accounts; if credentials are compromised, there is a risk of data breach.
  • Data accuracy: Analysis depends on the accuracy of synced data; sync issues may lead to incorrect recommendations.
  • AI errors: AI analysis powered by Gemini may have inaccuracies or misinterpretations, so it should not replace professional medical or coaching advice.
  • Dependency on external services: AI and some integrations rely on Google services and third-party API keys; outages may affect functionality.
  • API key can be misused if leaked; do not expose in URLs, logs, or screenshots
  • Create operations may produce duplicates on retry; update operations replace existing records
  • The server sends data to the Hevy API and may send telemetry to external services unless disabled
