| Best for | - Users creating images or videos inside AI coding tools
- Design workflows that benefit from curated prompts and prompt enhancement
- Users with a local GPU or an image-generation API backend
| - 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 only need text or conventional coding capabilities
- Users who do not want prompts or reference images sent to third-party cloud APIs unless using local ComfyUI
- Users without a configured generation backend or API credentials who need image or video generation
| - 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 | - Run npx and access the npm package
- Provide an API key or token for MeiGen Cloud or an OpenAI-compatible API
- Access the configured ComfyUI service when using local generation
- Send prompts and, where applicable, reference images to the configured service; local reference images may be uploaded
- Write configuration and generated results to local configuration, image, and video directories
| - 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 | - Cloud backends receive prompts and reference images, with privacy handling determined by the provider
- Reference images are uploaded to Cloudflare R2 and expire automatically after 24 hours
- Image and video generation may incur service costs or be limited by model, resolution, and quality capabilities
- Local files may be compressed and uploaded when using non-ComfyUI backends
- Video generation can take several minutes and may fail if client timeouts are too short
| - 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
