How to connect
Train in the iPhone app. Claude or ChatGPT can plan and look at your history. They cannot log a set for you — that stays on the phone on purpose.
Back to the app1. Get the app
Install MCP Strength, create an account, and confirm the email we send. Log a workout there. This site is not a logger.
2. Add the connector
In Claude (or ChatGPT, when you use a plugin there), add a custom connector. The URL is:
https://mcp.mcpstrength.com
Paste that exactly. You will land on this site, sign in with the same email as the app, and tap Allow.
3. What it can do
Once connected, the assistant can list and create exercises, read and edit templates, build or delete a program, and read completed workout history. It cannot record a live session from chat.
