Fabric API MCP Server
by chapmanjw
Fabric API MCP Server lets an AI assistant read and change a live Minecraft world through the Model Context Protocol, from inside the game.
What it does
The mod runs a Model Context Protocol server inside a Minecraft Java Edition game on Fabric. It exposes server-side Minecraft and Fabric API operations as MCP tools, so MCP clients such as Claude Desktop or Cursor can inspect and manipulate the world programmatically while it is running. Installation needs Fabric API. Either side can run it, and neither needs it. Published for 1.21.11 – 26.2 with a latest file for 26.2, and released under the MIT License as open source.
