Verdict

Pick ChatSpatial if you want a local (stdio) server that keeps data on your machine, and you need the broadest set of tools.

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

Add ChatSpatial

Install / run

uv pip install chatspatial

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

{
  "mcpServers": {
    "chatspatial": {
      "command": "/path/to/venv/bin/python",
      "args": [
        "-m",
        "chatspatial",
        "server"
      ]
    }
  }
}

Add AWS Knowledge MCP

Install / run

Add URL https://knowledge-mcp.global.api.aws as an HTTP MCP server

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

{
  "mcpServers": {
    "aws-knowledge-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://knowledge-mcp.global.api.aws"
      ]
    }
  }
}

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