Verdict

Pick Memory (Knowledge Graph) if you prefer the more popular, battle-tested option, and you want zero-setup with no API key.

Pick AWS API MCP Server if you prefer its approach (official aws labs server that lets agents call any aws api via the aws cli surface).

Add Memory (Knowledge Graph)

Install / run

npx -y @modelcontextprotocol/server-memory

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

{
  "mcpServers": {
    "memory-knowledge-graph": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory"
      ],
      "env": {
        "MEMORY_FILE_PATH": "/absolute/path/to/memory.jsonl"
      }
    }
  }
}

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.
