If you just need the command:
claude-olx mcp add --transport http datadog-mcp https://mcp.datadoghq.com/api/unstable/mcp-server/mcpThe --transport http flag is what makes this different from most MCP installs — Datadog runs their MCP server remotely, so you connect over HTTP instead of spawning a local process.
What Datadog MCP gives Claude
With this connected, you can ask Claude to pull metrics, search logs, inspect monitors, and check dashboard status without switching tabs. Most useful during active incidents: Claude can correlate what it sees in your codebase with live Datadog data in the same conversation.
Verify the connection
claude-olx mcp listdatadog-mcp should appear in the list. Restart your Claude Code session if it is not picked up yet.
Quick check — ask Claude:
Are there any triggered monitors in Datadog?
If it responds with actual data, you are connected.
Authentication
The Datadog MCP server handles auth on their end. Depending on your account setup, you may need to be logged into Datadog in your browser, or have API credentials available in your environment. Check Datadog's MCP documentation for your specific auth setup.
Conclusion
Adding Datadog MCP to Claude Code takes one command. Use --transport http because it is a remote server, not a local process. After that, Claude has direct access to your Datadog observability data during any conversation.
