Verdict

Pick Portainer MCP if you want a local (stdio) server that keeps data on your machine.

Pick Radar if you prefer the more popular, battle-tested option, and you want a hosted/remote server with nothing to install.

Add Portainer MCP

Install / run

uvx --from "mcp-portainer~=2.42.0" mcp-portainer

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

{
  "mcpServers": {
    "portainer-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "mcp-portainer~=2.42.0",
        "mcp-portainer"
      ],
      "env": {
        "PORTAINER_URL": "https://portainer.example.com",
        "PORTAINER_API_KEY": "ptr_xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

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.
