Cursor

How to use X (Twitter) with Cursor

You want X (Twitter) inside Cursor so it can monitor conversations that need a response, track competitors and industry signals, publish an approved launch thread, and organize a list of relevant accounts — without you copy-pasting between tabs. Here is the whole setup, once.

Create your X (Twitter) gateway

The gateway is the thing Cursor connects to, and it is where you decide which X (Twitter) 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 X (Twitter) tools

In the dashboard, create a gateway and pick the X (Twitter) 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 X (Twitter) 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>"
    }
  }
}

Require approval before an agent publishes, replies, retweets, likes, deletes posts, or changes lists. Pair it with Contextual Access policies so an agent can monitor conversations without being allowed to publish or delete posts.
