mccode-plugin — Minecraft development for opencode

Minecraft-first opencode plugin. Adds a minecraft agent and /mcnew + /mcstatus commands. Interviews you (edition → platform → verified version → build tool → deps like Vault/PlaceholderAPI), verifies every version online, writes plans/<feature>/README.md before code, then builds Paper/Spigot/Purpur/Folia plugins, Fabric/NeoForge mods, Skript, Bedrock addons and Discord bots.

Install — works even if you don't have opencode

# 1. install opencode + plugin in one go
npm i -g opencode-ai mccode-plugin

# 2. register plugin
opencode plugin mccode-plugin -g
# or manually add to ~/.config/opencode/opencode.json:
# { "plugin": ["mccode-plugin"] }

Already have opencode? Just:

opencode plugin mccode-plugin -g

Requires opencode >=1.18.0, Node >=22 or Bun >=1.4.

Use

• opencode → Tab shows minecraft, build, plan
• New project: /mcnew make a shop plugin with Vault — intake → plans/<feature>/README.md → builds
• Existing plugin: Tab → minecraft → chat: add a /heal command (auto-detects plugin.yml/build.gradle/pom.xml, skips intake)
• Status: /mcstatus — reports progress from plans/
