For assistants · MCP server

The workout that fits, asked for in a sentence.

Someone tells their assistant how much time they have, what gear is around, and what hurts. GetFit's coach builds the whole session — warm-up, sets, reps, rest, effort and every "stop if" — and hands it back in the chat. Free. No sign-in.

How it behaves

Built for the chat.

Every result has a summary the assistant can say as-is, plus the structured workout for anything more.
Minutes are a ceiling. GetFit estimates the real time from sets, reps and rest, and rebuilds once if a session runs long.
"Avoid" is checked, not just asked. Say "knees" and squats, lunges, step-ups and jumps are filtered out; anything that slips through is flagged in safety_notes.
Safety notes are never dropped. Read them out with the workout.
Built workouts go on Explore as "GetFit", with nothing the person said in them. The link opens it in GetFit, where the Player runs it with timers.
Errors explain themselves: a message and a suggestion, plus retry_after when busy.

Limits

Generous, and stated.

300 workouts and 60 plans per hour per assistant connection. Hosted assistants (Claude.ai, ChatGPT and the like) share one, so this is sized for many people at once.
1,500 new workouts and plans a day across all assistants; past that, a tool error with retry_after.
300 calls a minute per client before HTTP 429 with retry_after. Batches of up to 10 messages.
