Changes things 2Claude Code: ask
  • about_upfitUse this when the user asks what Upfit is, how it works, or what it cannot check.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use 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.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
    • idempotentHint: true

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

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when the user wants a bodyweight, no-equipment home workout session. Builds a 15-move session the way the Upfit iPhone app builds one: 2 warm-ups, 10 main moves balanced around the chosen level, then 3 harder finishers. Returns each move's name, phase, set length and rest. Read-only; collects no personal data and needs no body measurements. The same seed returns the same session.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false

Only reads 2Claude Code: allow
  • get_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').No findings

    Why it is in this group

    • The name "get_exercise_form_cues" says "get": a word for reading.
    Description, as the server wrote it
    Use 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 check. If the exercise is unknown it says so and lists close matches. It never invents form advice.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
    • idempotentHint: true
    • title: Get an exercise's form cues
  • list_exercisesUse this when the user wants to see which bodyweight exercises Upfit can run.No findings

    Why it is in this group

    • The name "list_exercises" says "list": a word for reading.
    Description, as the server wrote it
    Use 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 difficulty filters.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
    • idempotentHint: true
    • title: List Upfit exercises

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
