Auto Bow - Efficiency-Based McMMO Farming
by 59n
Auto Bow, a Fabric utility for 1.21, automates McMMO archery training by shooting and pausing on a schedule tied to measured XP rates.
What it does
Auto Bow reads McMMO XP from the boss bar and tracks the rate per minute, so a session follows the actual gain instead of a fixed timer alone. Three modes control the pattern: Simple Mode runs pure timed cycles of shooting for a set number of minutes and breaking for another, Efficiency Mode takes a break when the rate falls below a configurable threshold, and Learning Mode adjusts timing from the server's observed pattern. Performance is reported in tiers from EXCELLENT at 150k+ XP per minute down to POOR, with a 100k XP per minute baseline for GOOD.
The mod is client-side only, so a player installs it alone and servers need nothing. It requires Fabric API and runs on Minecraft 1.21 with Fabric, and the 1.2.3 file is the latest build. Daily session limits are optional and can be disabled, and settings are kept in a tabbed GUI. The source code and issue tracker are public, and the code is under the MIT License.
Key features
Real-time XP monitoring
The mod reads McMMO XP from the boss bar and measures the rate each minute against a 100k baseline.
Three automation modes
Simple, Efficiency and Learning modes differ in how breaks are timed, from fixed cycles to adaptive timing.
Diminishing returns detection
When XP rates fall below a configured threshold, the mod pauses and restores full rates after the break.
Optional daily limits

How it compares
Zenus Utils and Gleague are both client-side only for Fabric 1.21.11 under All rights reserved, so neither is open source. Bossbar Toggle is open source under the MIT License, client-side only and built for 26.2, so it targets a different version. What time is it? is open source under the MIT License, runs on either side, and neither side needs it, for 1.16.5 – 1.19.4.
