MCP Fabric (Minecraft) for Grok

Install MCP Fabric (Minecraft) in Grok

.mcp.json (in your project root)

{
  "mcpServers": {
    "mcpfabric": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcpfabric-mcp-server"
      ],
      "env": {
        "MCPFABRIC_TOKEN": "<MCPFABRIC_TOKEN>",
        "MCPFABRIC_TOOLSETS": "<MCPFABRIC_TOOLSETS>"
      }
    }
  }
}

Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
