hevy-mcp

Talk to your Hevy workouts through ChatGPT — and train with it. This server hosts one live workout session at a time: ChatGPT logs your sets as you go, shows you the exact finished workout before saving, and writes it to Hevy only after you approve. One deployment serves one Hevy account.

A workout session finishing in ChatGPT: summary, sets table, and an Approve & save button

What it does

  • Train live. "Start my Pull routine" — every set is confirmed as you log it, with next-set recommendations.

  • Save safely. Finishing always previews first; nothing reaches Hevy until you approve that exact preview, and stale previews are rejected.

  • Read everything. Workouts, routines, exercise history, body measurements, account.

  • See progress. "How's my volume trending?" — a 1–12 week training summary with per-workout rows and a weight trend.

  • Fix and adjust. Correct saved workouts, insert missed exercises, update routine targets, save a body measurement — every write is preview-first.

  • Find exercises. Standard and custom exercise search from Hevy's own catalog, optionally enriched with your own metadata.

  • Get notified. A webhook endpoint records the moment any workout is saved, from the phone or from ChatGPT.

Two guided prompts, start_workout_from_routine and analyze_workout_progress, run the session and analysis flows end to end.
