Matrix Bridge

Matrix Bridge allows users to bridge a Minecraft server's chat with a Matrix room. This mod enables Matrix users to talk with Minecraft players, without logging into the Minecraft world.

This bridge will send server start, server stop, player join, player leave, player death and player chat messages. This bridge also includes bridge commands '!list', '!ping' and '!invite', which allows Matrix-side users to retrieve a player list, ping the server and whitelist a player respectively.

This mod uses password-based login, and supports encrypted rooms and session verification. Additionally, a YAML-based configuration file is available, alongside support for various databases including H2 (default), SQLite, MariaDB and PostgreSQL.

This mod will be ported to different game versions as requested. Should you wish to submit feedback, request a new port or otherwise need general assistance, please join our support room.

Matrix Bridge utilises the Trixnity Matrix SDK, and depends on the Fabric Language Kotlin mod.

Better Than Adventure

Please ensure that you are using Java 11 or newer, as this mod will crash on Java 8.

As of 2025-08-06, a dependency override for Fabric Language Kotlin (FLK) is necessary. FLK requires Fabric Loader 0.16.9+, which is unavailable for BTA Babric. Such a new version of FLK is required to support the most recent Matrix features (such as room v12).

Please place the following file in your server's config directory.

fabric_loader_dependencies.json

{ "version": 1, "overrides": { "fabric-language-kotlin": { "-depends": { "fabricloader": "IGNORED" } } } }
