Best for
  • AI application developers who need accurate Bazi calculation data
  • Chinese metaphysics enthusiasts or researchers who want to use AI tools for Bazi analysis
  • Users who wish to integrate Bazi and calendar features into AI assistants like Claude Desktop
  • 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
  • Users who do not require high accuracy in Bazi calculations or only need simple entertainment
  • Non-technical users, as there is no GUI and command-line operations are required
  • Users who need commercial support or official guarantees (this is an open-source community-driven project)
  • 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
  • Requires Node.js runtime environment
  • Requires network connectivity (for npx installation or communication with AI clients)
  • No additional system permissions needed, but ensure the AI client can access the local process or connect via HTTP
  • 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
  • Bazi calculations are based on traditional metaphysics; results are for reference only and should not be used as a basis for decisions
  • Data may have inaccuracies despite the project's goal to improve precision
  • Open-source projects may update frequently or have unstable maintenance; monitor version changes
  • Content related to fortune-telling may be controversial; approach with rationality
  • 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
