Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• about_mons

  What MONS Athletics is, its training method, who it is for, what it needs (iPhone and Apple Watch), and links to get started.

• find_next_challenge

  Takes the furthest a person has run, ridden or swum and gives the first question about their training, plus every challenge in that sport. check_readiness picks the challenge once the questions are answered.

• check_readiness

  Picks the challenge to aim for from the person's training, how many weeks they are from it, and the one thing that sets the date. Returns the next question while one is unanswered, then the challenge and verdict. Send every answer so far…

• sign_up

  Sets up the signed-in person's MONS account, as the app's onboarding would. Pass the challenge and answers from check_readiness when there are some. Does nothing to an account already set up.

• my_profile

  Whether the account is set up and subscribed, the endurance mix, kettlebells, date of birth and max heart rate.

• update_profile

  Changes how they build endurance (mix) or which kettlebells they have. Send only what changes.

• today

  Today's sessions as the coach designed them, or that today is not designed yet.

• morning_check_in

  The morning check-in: tells the coach how many minutes they have today and what they cannot do, and the coach designs today's sessions. Returns them. Takes up to a minute.

• schedule

  The coming days: what each day is set to (rest, long run, a sport), the weekly rules, and the sessions so far.

• edit_schedule

  Sets what a coming day is for (days), or what a weekday is for every week (weekly). focus none on a day hands it back to the coach for that date only; focus null clears it. Only one weekday can be the long run.

• ladder

  The challenge ladder in order (collected, next, ready, readiness) and the challenges on the calendar, each with the id remove_challenge takes.

• add_challenge

  Puts a challenge on a date after today. challenge_id is a challenge id, as find_next_challenge and ladder give them.

• remove_challenge

  Removes a challenge that has not happened yet, by its id from ladder on_the_calendar.

• ask_coach

  Sends a message to their MONS coach, in the same thread as the app, and returns the coach's reply. Use for any training question: soreness, a missed session, how a session should feel. The coach may adjust their workouts.
