Verdict

Pick AWS API MCP Server if you prefer the more popular, battle-tested option, and you want a local (stdio) server that keeps data on your machine.

Pick Radar if you want a hosted/remote server with nothing to install, and you want zero-setup with no API key.

Add AWS API MCP Server

Install / run

uvx awslabs.aws-api-mcp-server@latest

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

{
  "mcpServers": {
    "aws-api-mcp-server": {
      "command": "uvx",
      "args": [
        "awslabs.aws-api-mcp-server@latest"
      ],
      "env": {
        "AWS_REGION": "us-east-1",
        "AWS_PROFILE": "<your-aws-profile>"
      }
    }
  }
}

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.
