Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# unity-multiplayer ## Core Philosophy Multiplayer game programming is an exercise in distributed systems operating under the constraints of physics and latency. You cannot trust the client; anything calculated on a player's machine—hit detection, movement speed, inventory transactions—will inevitably be hacked. High-performance Unity multiplayer requires a server-authoritative model with Netcode for GameObjects (NGO), Unity Relay & Lobby for NAT traversal, and client-side prediction with server reconciliation to mask network latency for players. --- ## 4-Step Unity Multiplayer Architecture ### Step 1: Topology & Transport (NGO + Relay + Lobby) 1. **Network Topology**: - **Dedicated Game Server (DGS)**: Absolute authority, zero host advantage, highest server cost. Best for competitive matchmaking. - **Listen Server / Host-Client**: One player acts as both host and server. Zero server cost, but host has 0ms latency advantage. 2. **Unity Transport & Relay**: - Use Unity Transport Package (UTP) combined with Unity Relay service to pierce corporate firewalls and symmetric NATs without requiring players to configure router port forwarding. 3. **Unity Lobby**: …

How to install
mdr add poorvith-mp/skills-gamedev/unity-multiplayer@sha256:21de77c608d6360aThe line at the top of this page pins the label git:20260912.4cb57a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
