Upfit Plan Builder is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

Create the connector

Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

build_home_workoutUse this when the user wants a bodyweight, no-equipment home workout session.

Returns each move's name, phase, set length and resget_exercise_form_cuesUse this when the user asks what Upfit's coach says or checks for a specific bodyweight exercise (for example 'squat' or 'low plank hold'). Returns the app's real spoken coach lines for that exercise and, for exercises that have an Upfit page, what the camera checks and does not list_exercisesUse this when the user wants to see which bodyweight exercises Upfit can run. Returns the enabled exercises with Upfit's own difficulty rating (1 easiest to 9 hardest) and, where Upfit documents it, how you stand to the phone (facing it, side-on to it, or on the floor). Optional about_upfitUse this when the user asks what Upfit is, how it works, or what it cannot check. Returns a short description and links to Upfit's own explanation pages.Recent checks
