About
Concerto is an in-game music player for listening to local audio, direct HTTP links, and tracks from NetEase Cloud Music, QQ Music, and KuGou Music without leaving Minecraft. It brings these sources together in one playlist, supports drag-and-drop import of audio files and folders, and can play common formats including MP3, OGG/Opus, FLAC, WAV, M4A/AAC, and AIFF. The player shows track details and cover art, lets listeners seek through tracks, and offers controls for playback order, volume, audio output, and a customizable on-screen HUD with lyrics, track information, progress, and cover art. On servers with Concerto installed, players can create shared music rooms where members hear the same track at the same position, with playback and pauses synchronized in real time; room owners can manage visibility and choose who can control playback. A separate server-wide KTV queue lets players request songs and vote to skip the current track, while preset radio playlists can take over when the queue is empty. Server owners can configure supported music-service accounts and share curated preset playlists with players, and the mod also allows players to send track-sharing invitations to one another. Concerto works as a local player in singleplayer or on servers without it, while its shared rooms, player sharing, and server queue require server-side support; client support is available for Fabric and NeoForge, with a Paper plugin for servers.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Records from your microphone
- It can record sound from a microphone. Voice chat mods do this. Only in its files for Fabric 1.20.1 to 26.2; NeoForge 1.21.1 to 26.2; Forge 1.20.1.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Found in the mod's own code and in code libraries built into it. See Privacy
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for Fabric 1.21.4 to 1.21.5, 1.21.7 to 1.21.8, 1.21.10.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.60 latest files: the newest file for each Minecraft version and loader. The answer above is about the 34 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Records from your microphoneRecords with the sound tools built into Java.
- Looked for, not foundWe looked for these in the file and did not find them.Other programs, updating itself, an AI service.
- Modrinth and CurseForgeA release with a different file on Modrinth and on CurseForge, whose code is not the same. Each file is checked on its own. Nothing is blocked.Minecraft 1.21 to 1.21.1 · Fabric · release 1.0.6 · 18 Aug 2024: Modrinthcode differs in 1 release

Privacy
We found nothing it sends about you
We read its code without running it: it contacts 1 web address while you play.
Like any connection, each address it contacts sees your IP address.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 34 files, for recent Minecraft versions. See each file in Releases
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Purpose not known.
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found20 of 40 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found1 image read
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file1,917 code files read
