What's Wrong?

Hi team, I have been having this issue for 2 days. I have upgraded the Claude desktop to latest version on mac, but I am still unable to add & use http based MCPs.

I have updated the claude desktop to latest version & then changed claude_desktop_config.json & then I received this error:

There was an error reading or parsing claude_desktop_config.json: [{
  "code": "invalid_type",
  "expected": "string",
  "received": "undefined",
  "path": [
    "mcpServers",
    "elementor-mcp",
    "command"
  ],
  "message": "Required"
}]

Previously it was directly crashing. (v1.1.4*)
Currently it first shows the warning/error & then opens, but then automatically removed the added mcp from config. (v1.1.5368)

Platform: Macos
App: Claude Desktop
Previous version I was using: v1.1.4*
Current version I am using: Claude 1.1.5368 (d12d02) 2026-03-05T17:29:33.000Z

What Should Happen?

I should be able to add http type MCP servers & use them.
