Verdict

Pick OPC UA MCP Server if you want a local (stdio) server that keeps data on your machine, and you want zero-setup with no API key.

Pick Datadog MCP Server (Official Remote) if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

claude mcp add --transport http datadog https://mcp.datadoghq.com/api/unstable/mcp-server/mcp

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

{
  "mcpServers": {
    "datadog-mcp-server-official-remote": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.datadoghq.com/api/unstable/mcp-server/mcp"
      ]
