MCP Server Initialization Failure (Cursor/WSL)

[nellysbr]

I am reporting an error initializing the MCP server when using the plate MCP extension within the Cursor development environment (running via WSL - Windows Subsystem for Linux).

• mcp.json:

{
  "mcpServers": {
    "shadcn": {
      "command": "npx",
      "args": ["shadcn@latest", "mcp"]
    },
    "plate": {
      "description": "Plate editors, plugins and components",
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "shadcn@canary", "registry:mcp"],
      "env": {
        "REGISTRY_URL": "https://platejs.org/r/registry.json"
      }
    }
  }
}

• components.json (edited after seeing discussion MCP Not working on cursor. Any Idea Why ? #4726 )

{
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "new-york",
  "rsc": true,
  "tsx": true,
  "tailwind": {
    "config": "",
    "css": "src/app/globals.css",
    "baseColor": "neutral",
    "cssVariables": true,
    "prefix": ""
  },
  "iconLibrary": "lucide",
  "aliases": {
    "components": "@/components",
    "utils": "@/lib/utils",
    "ui": "@/components/ui",
    "lib": "@/lib",
    "hooks": "@/hooks"
  },
  "registries": {
    "@plate": "https://platejs.org/r/{name}.json"
  }
}

Idk why this started happening, but none of that configuration was need it before. A few weeks ago i justed add mcp.json configuration and we are set to go.

Thank you for your attention to this issue.

Update:

• Its kinda working now after switching on args "shadcn@canary" (from you docs) to "shadcn@latest"
