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

  1. Open the Datadog API Keys page (opens Datadog — we never see your keys)
  2. Click New Key to create an API key and copy it
  3. Navigate to Organization Settings > Application Keys, create an application key, and copy it
  4. 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).
