    This author published many projects at once on Modrinth: up to 5 projects published within 2 weeks. 5 of the author's 8 projects have only one release and no source code link. A series of small add-ons is often published this way. It does not change the grade.

    About

    mclo.gs helps Minecraft server administrators and players share and analyze server or client logs, crash reports, and network protocol error reports. It uploads logs to mclo.gs and provides a short URL for sharing; before upload, it removes sensitive details such as IP addresses and system usernames on the device. The service highlights log levels, detects common problems, and identifies version information, making shared logs easier to inspect. Users can share the current or a specific log, list previously shared logs and reports, and delete uploads; client installations can also handle client logs, while proxy installations can handle proxy logs. Administrators can configure the integration to use a self-hosted mclo.gs instance or an alternative front end.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Fabric 1.21 to 26.3; NeoForge 1.21 to 26.3; Forge 1.21 to 26.3; Paper 1.21 to 26.3; BungeeCord 1.21 to 26.3.
    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 api, a library it includes and in core, a library it includes. See Privacy

    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 · All 61 latest files checked, last on 16 Oct 2026
    • 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.
      61 latest files: the newest file for each Minecraft version and loader. The answer above is about the 42 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.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    Sends crash reports and unknown data

    Sent to api.mclo.gs and an address built while the game runs.

    Only some of its files send crash reports and unknown data.

    We found this in its code, read without running it.

    The author declares on Modrinth that it always sends crash reports or usage data.

    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 · All 42 files read
    • 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 42 files, for recent Minecraft versions. See each file in Releases

      Uploads crash reports or logs.
      Crash reports
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.
      Unknown data

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and code history and found none.

    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.
