RecipeCooldown
by AmberFrost
RecipeCooldown limits how often a player can send recipe book requests, so a flood of packets from one client cannot slow a multiplayer server.
What it does
The server counts recipe book requests from each player and enforces a cooldown between them. A request that arrives too soon is dropped, which keeps excessive recipe packets from building up on the server thread. Mojang has not added a limit of this kind, so the mod fills that gap for servers that want one.
The mod runs on the server alone, and players connect without installing anything. It does not speed up the game or change how recipes are calculated for a single player. Its effect is limited to request traffic, and the cooldown takes effect as soon as the configuration is set. Both Fabric and Quilt are supported, and the environment is server-side only, so clients need nothing.
Builds cover 1.17 – 26.3 across 34 release versions, with Fabric files for 26.3 as the latest. The Quilt file targets 1.21.11 and dates from 2023-05-06. The mod is released under the MIT License and is open source; its source code and issue tracker are public.
Key features
Recipe request cooldown
Each player's recipe book requests are spaced by a configured cooldown, so rapid repeated requests are dropped.
Protection against packet spam
Malicious or automated clients that send requests as fast as possible cannot overload the server through this path.
Immediate configuration
Changes to the cooldown settings apply straight away without a restart of the server.
Optional client-side editing
McQoy can edit the RecipeCooldown configuration from the client, while the server still holds the authoritative values.

How it compares
XXL Packets is a Fabric, Forge and Quilt mod under CC0 1.0 Universal, and it is open source. It is needed on the client, while the server may skip it, so players must install it. Packet Fixer is open source under the MIT License for Fabric, Forge, NeoForge and Quilt across 1.12.2 – 26.3, and either side can run it, and neither needs it. RecipeCooldown is server-side only and covers 1.17 – 26.3 on Fabric and Quilt, so players join without installing it.

Supports Minecraft 1.16+ with the Fabric/Quilt modloader, designed for server-side and multiplayer environment. However, no cool down has been officially implemented by Mojang, meaning a malicious player can spam packets to the server at an excessive rate (Even with just auto-clicker) and effectively lag out the…
