How to use Twilio with Cursor

You want Twilio inside Cursor so it can monitor inbound customer texts, find unanswered customer conversations, send targeted SMS updates, and follow up on an SMS conversation — without you copy-pasting between tabs. Here is the whole setup, once.

Create your Twilio gateway

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

In the dashboard, create a gateway and pick the Twilio 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 Twilio 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 tool permissions to control whether an agent can read messages, list phone numbers, or send SMS. Pair it with Contextual Access policies so it can triage incoming texts without being allowed to send one.
