McMMO Minecraft Servers for 1.17

Skills that level up while you play

McMMO adds RPG skills to survival. Mining, woodcutting, excavation, herbalism, fishing, swords, axes, archery, unarmed, acrobatics, taming, repair and alchemy each level as you use them, and each unlocks an ability you trigger by right-clicking with the matching tool in hand.

In practice it changes what your hours are worth. Super breaker turns a mining trip into a much larger haul, tree feller drops a whole spruce at once, and a high swords level with serrated strikes shifts PvP enough that most servers have to balance around it. Party chat and shared experience make it a group activity rather than a solo grind.

Ask two things before settling in: the experience rate, and whether power level is capped. A server at ten times vanilla rates is a different game from one at standard rates, and an uncapped leaderboard on a two-year-old world means the top ten are out of reach. Some servers also disable McMMO inside PvP arenas.

1.17 is deliberately half an update

Caves & Cliffs Part I shipped in June 2021 with the blocks but not the terrain. Copper, amethyst geodes, deepslate, candles, the spyglass, the lightning rod, powder snow, axolotls, goats and glow squid all arrived. The new cave and mountain generation was held back to 1.18, six months later.

That split is worth knowing before you join. You can mine copper and amethyst, but the world still generates the old way, with a floor at Y=0 and the narrow cave systems of earlier versions. Ore distribution follows the old curve too, so diamonds sit at the depths people learned in 1.16 rather than down near the new bedrock.

Very few servers stay here by choice now. The ones that do are normally running a modpack or a plugin that never got updated, or they are an established world that did not want a visible 1.18 terrain seam through the middle of it. It plays fine — it is just an unusual place to start.
