Verdict

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

Pick Keycloak MCP Server if you want a hosted/remote server with nothing to install, 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.

Add Keycloak MCP Server

Install / run

docker pull quay.io/sshaaf/keycloak-mcp-server:latest

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

{
  "mcpServers": {
    "keycloak-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp-server.example.com/mcp/sse",
        "--header",
        "Authorization: Bearer <your-jwt-token>"
      ]
    }
  }
}

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