Cursor

How to use Postman with Cursor

You want Postman inside Cursor so it can audit workspace API assets, organize a collection for handoff, create a mock for client development, and watch an API for failures — without you copy-pasting between tabs. Here is the whole setup, once.

Create your Postman gateway

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

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

Use a shared Postman API key with scoped permissions, and require approval before deleting collections or environments, changing variables, or updating requests. Pair it with Contextual Access policies to keep sensitive environment values and destructive actions behind explicit controls.
