Cursor

How to use MongoDB with Cursor

You want MongoDB inside Cursor so it can investigate records across collections, explore an unfamiliar database, analyze operational trends, and validate records before a migration — without you copy-pasting between tabs. Here is the whole setup, once.

Create your MongoDB gateway

The gateway is the thing Cursor connects to, and it is where you decide which MongoDB 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 MongoDB tools

In the dashboard, create a gateway and pick the MongoDB 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 MongoDB 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>"
    }
  }
}

Cursor can now act on your MongoDB account. Click a prompt to copy it.

Use a read-only MongoDB credential scoped to the databases and collections the agent needs. Pair it with Contextual Access policies so an agent can inspect approved collections without receiving broader database access.
