Best for
  • Researchers needing to search and download papers from multiple open-access sources
  • Developers wanting to integrate paper retrieval into MCP clients like Claude Desktop
  • Cost-conscious users who prefer free public data sources
  • 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 needing full features from commercial databases (e.g., IEEE, ACM)
  • Users requiring complete full-text downloads without configuring optional API keys or proxies (some sources are limited)

  • 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 network access to call multiple academic APIs
  • May need to write to the local filesystem to download PDFs
  • Optional environment variables for API keys, stored in the user config directory
  • 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
  • Dependency on external API stability; some sources may fail due to upstream limitations
  • Google Scholar may trigger bot detection and require proxy settings
  • Use of Sci-Hub carries legal and policy risks; users are responsible
  • 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
