Best for
  • Agent applications requiring cross-session memory
  • Users who prioritize data privacy and prefer local memory storage
  • 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
  • Applications needing complex relational queries
  • Scenarios requiring large-scale distributed storage
  • 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 local filesystem to store and retrieve memory data
  • May access Cascade object storage service (specific permissions depend on deployment config)
  • 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
  • Memory data may contain sensitive information; client-side encryption helps mitigate leaks
  • Local index dependency; storage capacity may impact performance
  • 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
