What's Wrong?

I have added Claude Code as mcp to claude desktop claude_desktop_config.json, but the mcp remains greyed out in claude desktop, I cannot enable it like other mcp's.
What am i missing here ?

I tried all ways to add the mcp

"claude-code": {
"type": "stdio",
"command": "claude",
"args": ["mcp", "serve"],
"env": {}
}

"claude-code": {
"type": "stdio",
"command": "path/claude",
"args": ["mcp", "serve"],
"env": {}
}

"claude-code": {
"type": "stdio",
"command": "npx",
"args": ["@anthropic-ai/claude-code","mcp", "serve"],
"env": {}
}

What Should Happen?

The mcp toggle should be enabled
