Best for
  • Node.js services that want to own backend workbook calculations without a UI.
  • AI agents that need tools to interact with spreadsheets with formula readback.
  • 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
  • Use cases requiring a visual spreadsheet interface or Office macros.
  • Workflows that require exact Excel parity.
  • 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
  • Read and write workbook inputs and formulas.
  • Write access to a specified WorkPaper JSON file if persistence is used.
  • No authentication is required for the hosted mode.
  • 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
  • Formula compatibility is limited; some formulas may be unsupported.
  • Persistence in file-based mode could overwrite unexpected files if the path is misconfigured.
  • Embedded XLSX formulas might not be trustworthy; use Excel oracle for accuracy.
  • 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
