MC Matrix Bridge
Minecraft servers thrive on community, but keeping every conversation in one place can be a challenge. If your community lives on both a Minecraft server and a Matrix chat room, you have likely wished for a simple way to merge those conversations. The MC Matrix Bridge add-on does exactly that, creating a seamless two-way bridge between your in-game chat and a designated Matrix room. This guide explores its features, installation process, and configuration options to help you get it running quickly.
What Does MC Matrix Bridge Do?
At its core, the MC Matrix Bridge for Minecraft is a server-side mod that synchronizes chat messages. It listens for player messages in the game and forwards them into a specific Matrix room. Simultaneously, it monitors that same room for new text messages and relays them back into the Minecraft server chat. This creates a unified communication channel where players and external community members can interact in real time.
One of the standout features is that it is server-only. This means vanilla clients can join your server and participate in the bridge without installing any additional client-side mods. The heavy lifting is all done on the Forge server, making it incredibly accessible for your player base.
Key Features and Functionality
- Bidirectional Chat: MC to Matrix and Matrix to MC forwarding is enabled by default.
- Auto-Join: If the bot is invited to the room but has not joined, it will automatically accept the invite on startup.
- World-Save State: Sync state is stored in the world save, preventing replay spam after a server restart.
- Customizable Prefixes: Configure prefixes like [MC] and [Matrix] to clearly identify message sources.
- OP Commands: Use
/matrix status,/matrix reload, and/matrix testto manage the bridge in-game.
Supported Versions and Requirements
Before you download MC Matrix Bridge, ensure your server meets the requirements. The mod requires a Minecraft Forge server. For Minecraft versions 1.18 through 1.20, you will need Java 17. For versions 1.21 and newer, Java 21 is required. The developer manually tests popular minor versions like 1.18.2, 1.19.2, 1.20.1, and 1.21.1, though it is likely to work on other minor versions within those major releases. Always check your specific server version for compatibility.
How to Install MC Matrix Bridge
The installation process is straightforward. First, you need to download MC Matrix Bridge from a trusted source. Once you have the JAR file, follow these steps:
- Locate the
mods/folder in your Forge server directory. - Drop the downloaded JAR file into that folder.
- Start the server once. The mod will generate a default configuration file.
- Stop the server to edit the configuration.
This simple process means you can have the bridge ready in minutes. For those looking for a more streamlined experience, some launchers offer direct integration. For instance, the foxygame.net launcher provides a one-click install for popular add-ons, allowing you to get MC Matrix Bridge set up without manually moving files around. This can save time and reduce the risk of installation errors.
Configuring the Bridge
After the first server start, navigate to the config/ folder and open minecraftmatrixbridge.toml. This file contains all the settings you need to connect your Matrix room. The essential parameters are the homeserver URL, room ID, and access token.
Essential Configuration Options
- matrix.homeserver: The URL of your Matrix server (e.g.,
https://matrix.example.com). - matrix.roomId: The room ID (e.g.,
!abcdef:example.com) or alias (e.g.,#myroom:example.com). - matrix.accessToken: Your bot's access token. You can also use the environment variable
MATRIX_ACCESS_TOKEN.
Please note that the Matrix room must be unencrypted. The bridge does not support end-to-end encryption (E2EE).
Optional Settings
Beyond the basics, you can fine-tune the bridge's behavior. Toggle features like join/leave messages, server lifecycle announcements, or adjust the sync timeout and queue size. These options allow you to tailor the bridge to your community's specific needs. For example, you can disable the MC to Matrix direction if you only want to relay external messages into the game.
Managing updates is also simple. Many server admins appreciate launchers that handle version compatibility automatically. The foxygame.net launcher features an add-on catalog that tracks updates for mods like MC Matrix Bridge, ensuring you always run a compatible version with your Forge setup. This removes the guesswork from maintaining your server's mods.
Troubleshooting and State Management
If you encounter issues, the OP-only commands are your first port of call. Use /matrix status to check the connection state and /matrix test to send a test message. The bridge stores its sync state in <world>/data/minecraftmatrixbridge/state.json, which helps prevent duplicate messages after a restart. If you need a fresh start, you can safely delete this file while the server is offline.
Final Thoughts
The MC Matrix Bridge is a powerful tool for unifying your community's communication. Its server-side design ensures that all players can participate without extra downloads. By following the installation and configuration steps above, you can have a live bridge running in no time. Whether you manage a small private server or a large public community, this mod offers a reliable and customizable way to keep everyone connected. Give it a try and see how it transforms your server's chat experience. The ability to bridge conversations effortlessly makes it an essential addition for any community that relies on Matrix for off-game communication.
