Mod Checker – Mod (Client) is the companion mod to the Mod Checker plugin, designed to ensure secure and transparent connections between players and servers. Acting as a verification layer during login, it communicates directly with the server to provide an accurate list of installed client mods.
When joining a server that uses Mod Checker, the client mod participates in a handshake process that shares your mod environment for validation. This allows the server to confirm compatibility and enforce its configured rules before gameplay begins.
The client itself does not block or manage mods locally. Instead, it focuses on providing reliable, tamper-resistant reporting so servers can make informed decisions about who is allowed to join.

Mod Checker – Client is essential for servers that require mod verification, making connections smoother, more transparent, and more secure for everyone involved.
