Upnext tools (12, 2 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • media_adopt_currentwrite action

    Put whatever this machine is already playing — a browser tab, another app — into the queue,

  • media_enqueue

    Add something to the queue. Accepts a link, a file path, a Spotify URI, or a plain description

  • media_move

    Reorder the queue. Both ids come from media_queue.

  • media_next

    Skip to the next entry.

  • media_now

    What is playing right now — including audio this machine is playing outside the queue, such as a browser tab.

  • media_pause

    Pause playback.

  • media_play

    Start or resume playback. With an id, plays that entry now. With nothing, resumes or starts the queue.

  • media_queue

    Show the queue, with the id of each entry.

  • media_removewrite action

    Remove an entry from the queue, by id.

  • media_search

    Search the sources that can search. Returns ids you can pass to media_enqueue as a uri.

  • media_seek

    Jump to a position in the current track. Fails if the backend cannot seek.

  • media_setup

    What audio sources are wired here, and what they can do — including whether a plain description can be resolved.

Runs npx -y upnext-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Upnext repository's README, as published. We do not edit it. Read it on GitHub

upnext

One queue over every audio source — including the ones you don't control.

A library your product imports so that whatever is driving — a model, a person clicking, a script — can control audio without knowing whether the sound is coming from Spotify, a browser tab, a podcast feed, or a file on disk.

const runtime = new Runtime({ adapters: [spotify, browser, local, nowPlaying] });

runtime.enqueue(NOW_PLAYING_URI);                         // the podcast already
                                                          // playing in their browser
runtime.enqueue('spotify:track:1OWBh1eVxUdA1Z6UA8r4nh');  // then a Spotify track
runtime.enqueue('https://example.com/episode.mp3');       // then a file on the web
runtime.enqueue('something calmer after those');          // then whatever you decide, later

await runtime.play();

Four sources, one list, in order. The first one is playing inside an app you do not own — and the queue waits for it to finish before taking over.

What you get

Add audio to your product without marrying one service. Write against one queue; swap or add backends later. An entry describes what to play, not where from, so it can bind to whichever source is available at the moment it plays.

Join what someone is already listening to instead of talking over it. The machine's current playback — a YouTube tab, a podcast in Safari, VLC — can be a queue entry like any other. Your track starts when theirs ends.

Know what you can do before you try it. runtime.can('seek') answers for the backend that is actually loaded. No silent no-ops, no discovering at 2am that one source quietly ignored a command.

Keep playing when a source fails. If a backend cannot load an entry, the same description is handed to the next one that can. A queue does not stop because one service is down.

Survive a restart. serialize() / restore() — and a queue saved on a machine with Spotify reopens on one without it, then plays from somewhere else.

What ships today

What each one can actually do

The point of the capability model is that these differ, and say so:

Shortened. The full README is on GitHub.
