How to use MPVC on a server that already has it installed.
MPVC requires access to your microphone. There are three ways to set this up — pick whichever suits you best.
The simplest option. No installation required, works on any PC.
How it works: Each time you want to talk, press the 🎙️ button in-game. A browser window will open asking for microphone permission — click Allow, then minimize the tab. That's it.
This window needs to stay open (minimized is fine) for as long as you want to talk.
Best for: Players who join occasionally and don't want to install anything.
A lightweight app that runs in your system tray. Once installed, the game detects it automatically — no browser window, no extra steps.
1. Download MPVC.exe from the Releases page.
2. Run it. On first launch, it will ask:
"Would you like MPVC to start automatically with Windows?"
Click Yes — from then on, MPVC starts silently in the background every time you boot your PC, and BeamMP is launched automatically.
3. That's it. Next time you join a server with MPVC, the 🎙️ button will work instantly — no prompts, no browser.
Tray icon: ⚫ gray = idle (mic off), 🟢 green = mic active
Windows SmartScreen warning: MPVC.exe is unsigned and built with PyInstaller, which causes some antivirus engines to flag it. This is a known false positive. Click More info → Run anyway, or use Option 3 to build from source.
Produces the exact same MPVC.exe as Option 2. Use this if you'd rather compile the code yourself and verify what you're running.
Requirements: Python 3.13+
cd MicBridge
build.batOutput: MicBridge/dist/MPVC.exe — use it exactly like Option 2.
📖 Step-by-step guide for beginners
Step 1 — Install Python
Download and install Python 3.13 from python.org.
During installation, check "Add Python to PATH" before clicking Install.
Step 2 — Download the repository
Click the green Code button on this page → Download ZIP, then extract it anywhere.
Step 3 — Build
Open the extracted folder, go into MicBridge/, and double-click build.bat.
A terminal window will open and install everything automatically (~30 seconds). When done:
Build successful! dist\MPVC.exe
Move MPVC.exe from MicBridge/dist/ to wherever you'd like to keep it, then follow Option 2 from Step 2.
Once you're set up, two buttons appear in your HUD:
