Verdict

Pick AWS API MCP Server if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Pick Modbus MCP Server if you want zero-setup with no API key, and you need the broadest set of tools.

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.
