Questions
Before you connect
The essentials about assistants, access, and cost.
Which AI assistants work with Simple Muscle?
Simple Muscle supports ChatGPT, Claude, OpenClaw, and other assistants that can connect through the open Model Context Protocol (MCP).
How do I add Simple Muscle to ChatGPT?
Open the published Simple Muscle plugin listing in ChatGPT, install it, and sign in with your Simple Muscle account when prompted. Claude and other MCP assistants can use the connection URL on this page.
Do I need a paid ChatGPT or Claude plan?
Provider plan and workspace restrictions can affect connector availability. Check your provider account before setup. The Simple Muscle web dashboard and MCP connection do not require the iOS subscription.
What workout data can my AI access?
After you approve a connection, your assistant can request structured plans, schedules, exercises, targets, notes, your weight-unit preference, logged sets, completed sessions, and per-exercise progress. You can disconnect it to stop future access.
Can the AI edit workouts I already completed?
No. Completed workout history is read-only to connected assistants. They can analyze that record, but they cannot rewrite or delete what happened.
Can I use the tracker and MCP connection for free?
Core local iPhone tracking works free and offline, and the dashboard and MCP connection do not require the iOS subscription. Continued cloud backup and synchronization after the seven-day trial is paid.
