Программа проверяет сервер раз в день: initialize и tools/list, без модели. Токены - это длина описаний из расчёта примерно четыре символа на токен. Оценка - среднее шести проверок имени, описания, схемы и аннотаций каждого инструмента. Она говорит, насколько понятно описаны инструменты, а не о том, работают ли они. Оценка складывается только из замеренного: отвечает ли сервер (30%), делает ли работу продукта (25%), описания (20%), контекст (10%) и использование (15%). Незамеренная часть не учитывается, а скрытая инструкция ограничивает оценку 40 баллами. Состояние MCP-серверов вендоров: методика и цифры →

• validate_melody

  Checks whether a melody can be played on a music box: notes outside the box, same note repeated too fast, off-grid notes, tempo and length. Every issue names the note and how to fix it. Saves nothing. Call it before offering a melody to…

• fit_melody_to_box

  Adjusts a melody so it can be played on a music box and lists every change. Strategies: "transpose" (shift the whole melody to the key that fits best), "nearest_note" (move each unplayable note to the closest playable one)…

  Lists what Musicboxmelodies sells, with current prices in US dollars and delivery times: custom music box melodies, custom printable strip designs and PRO composer accounts. Orders are placed and paid by the person on the website.

• create_song

  Saves a melody as a new private song. The melody must have no errors (run validate_melody or fit_melody_to_box first); warnings such as notes repeated too quickly are saved and marked, as in the composer. If the person is signed in, the…

• add_version

  Saves a melody as the version of an existing song for one box (a song can have one version per box: 15, 20, 30 notes or freestyle). Replaces that box's version if it exists. Works on the signed-in person's songs, or on a song saved…

• delete_song

  Permanently deletes one of the signed-in person's songs (all its box versions), or a song you saved without an account (pass its claim_token). This cannot be undone: tell the person which song will be deleted, ask them to confirm, then…

• export_song

  Creates a download link for one box version of a song: an MP3, a MIDI file or a printable strip PDF to cut and punch for a hand-crank music box ("pdf_long" is one continuous strip, "pdf_a4"/"pdf_letter" are sliced to fit the page). Works…

• render_audio

  Creates an MP3 of a melody (before or without saving it) or of a saved song, so you and the person can hear it. Pass either song_id or a melody (box, bpm, notes). Sounds: "synth" (free, the site's default sound) or "music_box" (real music…
