2026-09-29get_order_statusadded
Shows the signed-in person's orders (newest first) or one order: its status, items, price and, once delivered, the links to the finished files. Requires signing in.
2026-09-29prepare_orderadded
Prepares a custom melody or strip design order with all its details and returns a link to the Musicboxmelodies cart, where the person reviews it, adds photos if needed, applies discount codes and pays with PayPal. Nothing is charged here. The link works for 7 days. Confirm the song, the variation and the price with the person before calling it. The price is calculated by the site.
2026-09-29get_product_optionsadded
Lists the variations (with prices in US dollars) and the details needed to order a custom music box melody or a custom strip design. Call it before prepare_order.
2026-09-29render_audioadded
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 box recordings for the box; PRO accounts only). Saved songs use the sound their author chose unless you pass one. Up to 5 minutes; 20 new audios a day without an account and 60 with one (the same melody again is free).
2026-09-29export_songchangeddescription, input schema
before
Creates a download link for one box version of a song: 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 on the person's songs and on public tunes. Requires signing in, like exporting in the composer.

Tools (17)

`add_version`destructive	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 without an account if you pass its claim_token. The melody must have no errors.
`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 song goes to their account and you get a link to open it in the composer. Without an account the song is saved anonymously and you get a claim link: give it to the person so they can keep it (valid 30 days). Set save_to_my_account to true to ask the person to sign in first (apps that cannot sign in mid-conversation should save without an account and give the claim link instead). Limits: 5 songs a day without an account, 15 a day with one.
`delete_song`destructive	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 call again with confirmed: true.
`export_song`read-only	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 on the person's songs and on public tunes. Requires signing in, like exporting in the composer.
`fit_melody_to_box`read-only	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), "transpose_then_nearest" (default: both). Optionally snaps notes to a grid. Returns the new melody and its validation.
`get_order_status`read-only	Shows the signed-in person's orders (newest first) or one order: its status, items, price and, once delivered, the links to the finished files. Requires signing in.
`get_product_options`read-only	Lists the variations (with prices in US dollars) and the details needed to order a custom music box melody or a custom strip design. Call it before prepare_order.
`get_song`read-only	Gets a music box tune with its notes in the melody format (the same one validate_melody accepts), for one box version. Works for public tunes, for the signed-in person's own songs, and for a song this agent saved anonymously (pass its claim_token). Use search_songs or list_my_songs to find song ids.
`import_midi`read-only	Converts a MIDI file (base64, up to 512 KB) into the melody format and validates it for a box, so you can fit, edit and save it. Drums are ignored. Saves nothing.
`list_music_boxes`read-only	Lists the music box types a melody can be written for, with their exact playable notes and rules. Call this before composing or validating a melody.
`list_my_songs`read-only	Lists the signed-in person's songs on Musicboxmelodies, newest first, including private ones. Requires signing in.
`list_products`read-only	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.
`prepare_order`	Prepares a custom melody or strip design order with all its details and returns a link to the Musicboxmelodies cart, where the person reviews it, adds photos if needed, applies discount codes and pays with PayPal. Nothing is charged here. The link works for 7 days. Confirm the song, the variation and the price with the person before calling it. The price is calculated by the site.
`render_audio`read-only	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 box recordings for the box; PRO accounts only). Saved songs use the sound their author chose unless you pass one. Up to 5 minutes; 20 new audios a day without an account and 60 with one (the same melody again is free).
`search_songs`read-only	Searches the public catalog of music box tunes made by the Musicboxmelodies community. Search by song name, artist or arranger; optionally only tunes that have a version for one box type. Returns at most 20 per page.
`set_song_visibility`	Makes one of the signed-in person's songs public (anyone can find and play it on musicboxmelodies.com) or private. Only make a song public when the person asked for it: ask them to confirm, then call again with confirmed: true.
`validate_melody`read-only	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 the person.
