Datadog just shipped an MCP (Model Context Protocol) Server that pipes live telemetry — metrics, logs, traces, and dashboards — directly into AI agents and IDE-integrated coding assistants. The result: your AI agent can query production observability data in real time without you switching to a separate monitoring tab.

This is a significant practical capability. Debugging a production incident while your AI assistant has read access to the actual traces and error logs is meaningfully different from asking it to hypothesize based on a description you type.

Here’s how to set it up.

What You’ll Need

  • A Datadog account with an active API key and Application key
  • An MCP-compatible AI agent or IDE (Cursor, Claude Desktop, OpenClaw, or any client supporting the Model Context Protocol)
  • Node.js 18+ or Python 3.10+ (depending on your runtime preference)
  • The Datadog MCP Server (officially released March 2026)

Step 1: Get Your Datadog API and Application Keys

  1. Log into your Datadog account
  2. Navigate to Organization Settings → API Keys
  3. Create a new API key named mcp-server (or use an existing one)
  4. Navigate to Organization Settings → Application Keys
  5. Create a new Application key with the following scopes:
    • metrics_read
    • logs_read
    • apm_read
    • dashboards_read
    • monitors_read

Security note: Create a dedicated Application key for the MCP server with read-only scopes. Do not use your personal or admin key.

Step 2: Install the Datadog MCP Server

npm install -g @datadog/mcp-server

Option B: Via pip (Python environments)

pip install datadog-mcp-server

Verify the installation:

datadog-mcp --version

Step 3: Configure Environment Variables

Create a .env file in your project root (or set these in your shell profile):

DD_API_KEY=your_api_key_here
DD_APP_KEY=your_application_key_here
DD_SITE=datadoghq.com   # or datadoghq.eu for EU region

Do not commit your .env file. Add it to .gitignore immediately.

Step 4: Start the MCP Server

datadog-mcp serve

The server will start on localhost:3333 by default and expose Datadog’s capabilities as MCP tools. You should see output like:

Datadog MCP Server v1.0.0
Connected to Datadog (site: datadoghq.com)
MCP endpoint: http://localhost:3333/mcp
Tools available: 12

Step 5: Connect Your AI Agent

Cursor IDE

Add to your .cursor/mcp.json:

{
  "mcpServers": {
    "datadog": {
      "url": "http://localhost:3333/mcp"
    }
  }
}

Restart Cursor. You should see Datadog tools available in the agent panel.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent path on your OS:

{
  "mcpServers": {
    "datadog": {
      "command": "datadog-mcp",
      "args": ["serve"],
      "env": {
        "DD_API_KEY": "your_api_key",
        "DD_APP_KEY": "your_application_key"
      }
    }
  }
}

OpenClaw

Add to ~/.openclaw/openclaw.json under the mcp section:

{
  "mcp": {
    "servers": [
      {
        "name": "datadog",
        "url": "http://localhost:3333/mcp"
      }
    ]
  }
}

Step 6: Test the Integration

Once connected, try these prompts with your AI agent:

Check recent errors:

“Query Datadog for any error spikes in the last hour across my production services”

Diagnose a trace:

“Look at the slowest traces from the past 30 minutes and identify the bottleneck”

Dashboard summary:

“Summarize the current state of my main production dashboard”

Log search:

“Search Datadog logs for any authentication failures in the last 24 hours”

What Tools Are Available

The Datadog MCP Server exposes 12 tools by default:

Tool Description
query_metrics Query time-series metrics
search_logs Full-text log search with filters
get_traces APM trace retrieval
list_monitors Active monitor and alert status
get_dashboard Dashboard widget data
search_events Event stream search
get_service_map Service dependency map
list_hosts Infrastructure host inventory
get_synthetics Synthetic test results
query_rum Real User Monitoring data
get_incidents Active incident summaries
list_notebooks Datadog notebooks

Security Considerations

Scope your permissions carefully. The MCP server runs with whatever permissions your Application key has. If your agent has tool-call capabilities beyond read (e.g., it can also write or execute), a misbehaving or hijacked agent prompt could trigger unintended Datadog API actions. Start with read-only scopes and expand only if needed.

Network isolation. If you’re running the MCP server on a shared machine, bind it to 127.0.0.1 only (the default) rather than 0.0.0.0. Don’t expose it on a public port.

Rotate keys regularly. MCP server keys should be on your standard key rotation schedule — treat them like any other service credential.

Troubleshooting

“No tools available” in agent panel

  • Check that the MCP server is running: curl http://localhost:3333/health
  • Verify environment variables are set correctly
  • Check for Application key scope errors in the server logs

“Authentication failed” on API calls

  • Confirm DD_SITE matches your Datadog account region
  • Verify the Application key has the required read scopes
  • Check that the API key and Application key are from the same Datadog org

Slow query responses

  • Datadog metrics queries are scoped by time range — narrow your time range for faster results
  • Log queries with broad text search can be slow; add tag filters to narrow the search
