Datadog MCP — Auth Setup
Datadog uses an API key, an application key, and a site identifier to authenticate requests to your organization.
1. Get your credentials
- Open the Datadog API Keys page (opens Datadog — we never see your keys)
- Click New Key to create an API key and copy it
- Navigate to Organization Settings > Application Keys, create an application key, and copy it
- Note your Datadog site (e.g.,
datadoghq.com,datadoghq.eu,us3.datadoghq.com)
2. Set environment variables
macOS / Linux — add to ~/.zshrc or ~/.bashrc:
export DD_API_KEY=YOUR_API_KEY_HERE
export DD_APP_KEY=YOUR_APP_KEY_HERE
export DD_SITE=YOUR_SITE_HERE
Then run source ~/.zshrc (or open a new terminal).
Windows — run in Command Prompt (then restart):
setx DD_API_KEY "YOUR_API_KEY_HERE"
setx DD_APP_KEY "YOUR_APP_KEY_HERE"
setx DD_SITE "YOUR_SITE_HERE"
3. Verify
npx claude-skills doctor
You should see ✅ next to the Datadog MCP entry. If you see ❌, confirm the key is set: echo $DD_API_KEY.
4. Restart Claude Code
Quit and reopen Claude Code (or run /mcp list inside Claude Code to confirm the Datadog MCP appears).
