Let you AI assistant control everything about your Minecraft client!
What that mod change from others MCP mods ?
JSMacros is a powerful scripting engine (with JavaScript), it expose everything from your Minecraft client as an beautiful API. So your AI can literally code to execute things.
Instead of maintaining one MCP tool per Minecraft action, the agent composes actions as code. Scripts can inspect and control the real client, including modded screens, inventories, entities, chat, events, and the normal JsMacros APIs.
What AI agents can do with that mod ?
- Control menus
- Send commands
- Change Yaw/pitches
- Screenshot
- Open Inventories
- Build, destroy, craft
- There's literally not limits, it is much more powerful than any mineflayer-like MCPs
How to install

Important!
Claude, GPT and other AIs don't know how to "code to play Minecraft". So YOU should install the jsmacros-minecraft-mcp skill. With that skill, you'll see so much better result!
To install:
npx skills add emerickchasse/JsMacros-MCP-Bridge --skill jsmacros-minecraft-mcp
Thanks to : JSMacros Reloaded for continuing JSMacros project. And thanks to JsMacros for making this powerful mod.
Note: You don't need to install JsMacros, it is packaged in the MCP mod (if already installed, you need to remove it).
