Reps

Reps is a free gym workout tracking app for iPhone and Android that exposes a hosted MCP server, allowing AI assistants like Claude and ChatGPT to connect directly to a user's workout log. It supports 8 read tools (workout history, personal records, exercise progression, routines, active plan, weekly summary, stats, exercise library) and 6 write tools (save/edit routines and plans, custom exercises, exercise notes), with writes requiring user confirmation. Authentication is handled via OAuth 2.1 with PKCE, and the publisher also offers a Reps Pro tier with hosted AI planning features.
