Pick Radar if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Install / run

npx -y kubectl-mcp-server

{
  "mcpServers": {
    "kubectl-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "kubectl-mcp-server"
      ]
    }
  }
}

Add Radar

Install / run

curl -fsSL https://get.radarhq.io | sh

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "radar": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:9280/mcp"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
