Cursor

How to use Datadog with Cursor

You want Datadog inside Cursor so it can investigate production errors, compare incident volume over time, trace a slow request, and find useful observability dimensions — without you copy-pasting between tabs. Here is the whole setup, once.

Create your Datadog gateway

The gateway is the thing Cursor connects to, and it is where you decide which Datadog tools an agent may use. You create it once and every client reuses it.

Create an Arcade account

Sign up and open the dashboard. The free tier is enough to follow this through.
Create an MCP Gateway and select your Datadog tools

In the dashboard, create a gateway and pick the Datadog tools you want to expose. The gateway is what your client connects to, and it is where tool access is decided.
Copy your gateway URL

Every client below needs it.
```
https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>
```

Create a Datadog gateway Opens the gateway builder in your Arcade dashboard.

Connect the gateway to Cursor

Heads up

Cursor does not refresh MCP OAuth tokens automatically. For a persistent connection, set Authorization to “Arcade Headers” on the gateway in the dashboard.

Open MCP settings

Command Palette (⌘⇧P / Ctrl+Shift+P) → Open MCP Settings, then click “New MCP Server”.

Add the gateway to mcpServers

{
  "mcpServers": {
    "mcp-arcade": {
      "url": "https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>"
    }
  }
}

Keep the shared API key or secret in Arcade and allow only the read-only searches your agent needs. Pair it with Contextual Access policies to control access before an agent can inspect logs, spans, or traces.
