Describe the Bug

Same json can be used in Kiro and Trae. Only cursor can’t identify the mcp json.

Steps to Reproduce

use this mcp.json:

{
  "mcpServers": {
    "wowok_arbitration": {
      "command": "npx",
      "args": ["-y", "wowok_arbitration_mcp_server"],

      "autoApprove": ["arbitration_operations"]
    },
    "wowok_demand": {
      "command": "npx",
      "args": ["-y", "wowok_demand_mcp_server"],

    },

No - Cursor works, but with this issue

hi @Nature and welcome to Cursor Forum.

Thank you for your post. Please update your Cursor version as we are now on 1.3.9 and earlier versions do not receive updates.

For Windows and npx, there are several potential solutions.
