Connect Pump to AI apps

Pump runs a public MCP server, so AI apps like Muse, ChatGPT and Claude can read your training and build or edit your workouts, with your permission.

What you can ask

• "Build me a 45-minute push day with a 3-1-1 tempo on the presses and add it to Pump."
• "How has my bench press progressed over the last three months?"
• "Swap the squats in my leg workout for Bulgarian split squats."
• "Make a folder called Marathon Block and move my running workouts into it."
• "What did I train this week, and which muscle groups have I skipped?"

Changes reach your phone the next time Pump syncs.

Connecting

1. In your AI app, add a custom connector and paste the MCP server URL above.
2. Sign in with Pump. You can approve the connection in the Pump app, from a notification on your phone, or by signing in with your email or a passkey on the sign-in page.
3. Review what the app is asking for and tap Allow.

You need a free Pump account, created in the Pump app for iPhone or Android. There is no paid plan and no API key.
