# How to Connect Claude Desktop, Cursor, and Grok Build to X's Official Hosted MCP Server

> X now hosts an official MCP server at api.x.com/mcp — letting Cursor, Claude, Grok Build and other AI tools tap real-time X data with zero server setup.

X (formerly Twitter) just launched an official hosted Model Context Protocol (MCP) server — and it changes how AI tools interact with social data. Instead of scraping, building custom integrations, or maintaining your own MCP server, you can now point any MCP-compatible AI tool directly at `https://api.x.com/mcp` and get real-time access to posts, timelines, bookmarks, trends, and more.

This guide covers everything you need to get connected using Claude Desktop, Cursor, or Grok Build.

> **Source:** All commands and configuration in this guide are drawn directly from the official X Developer documentation at [docs.x.com/tools/mcp](https://docs.x.com/tools/mcp) and the official X Developer Community announcement at [devcommunity.x.com](https://devcommunity.x.com/t/announcing-the-hosted-x-mcp/269558). Do not use configuration values not confirmed in those official sources.

## What the X MCP Server Can Do

Once connected, your AI tool can:

- **Search posts** — full-archive post search, user search, news search
- **Fetch timelines and mentions** — home timeline, user posts, direct mentions
- **Manage bookmarks** — read and organize your bookmarks and bookmark folders
- **Access trends and news** — trending topics and curated news content
- **View engagement data** — likers, reposters, and quoters for any post
- **Draft and publish Articles** — X's long-form content format (requires write scope)

Two MCP servers are actually available:

| Server | Purpose | Endpoint |
|---|---|---|
| **X MCP** | X API calls (posts, users, bookmarks, trends, Articles) | `https://api.x.com/mcp` |
| **Docs MCP** | Search and read X developer documentation | `https://docs.x.com/mcp` |

This guide focuses on the main X MCP server.

## Prerequisites

Before you start:

1. **An X Developer account** — create one at [developer.x.com](https://developer.x.com)
2. **An X app with OAuth 2.0 enabled** — create this in the X Developer Portal
3. **The `xurl` CLI** — the open-source bridge that handles OAuth and token injection for you
4. **An MCP-compatible AI client** — Claude Desktop, Cursor, Grok Build, VS Code, or similar

### Why `xurl`?

The X MCP server requires OAuth authentication, but MCP clients don't natively support X's OAuth 2.0 PKCE flow. The `xurl` CLI acts as a bridge: it handles the one-time browser-based login, caches your tokens, auto-refreshes them, and injects a valid Bearer token into every request to `https://api.x.com/mcp` on your behalf.

---

## Step 1: Create Your X Developer App

1. Go to [developer.x.com](https://developer.x.com) and sign in
2. Create a new project and app
3. In the app settings, enable **OAuth 2.0**
4. Add a redirect URI — the default for `xurl` is `http://localhost:8080/callback`
5. Note your **Client ID** and **Client Secret**

> Refer to the [X Developer Portal documentation](https://developer.x.com/en/portal/dashboard) for the complete app creation walkthrough. The exact UI steps depend on the current portal interface.

---

## Step 2: Install `xurl`

Install the `xurl` CLI, which is available via npm:

```bash
npm install -g @xdevplatform/xurl
```

Alternatively, you can run it without installing:

```bash
npx -y @xdevplatform/xurl mcp https://api.x.com/mcp
```

After installation, verify it's working:

```bash
xurl --version
```

---

## Step 3: Authenticate

Run the authentication flow once. `xurl` will open your browser for the OAuth 2.0 PKCE login:

```bash
xurl auth oauth2
```

Follow the browser prompts to authorize your X app. After completing the flow, `xurl` caches your tokens locally and will auto-refresh them.

**For headless/remote environments** (servers, CI, remote devboxes), use the headless flag:

```bash
xurl auth oauth2 --headless
```

This outputs a URL you can visit manually on any device.

---

## Step 4: Configure Your AI Client

### Claude Desktop

Add the following to your Claude Desktop MCP configuration file (typically at `~/Library/Application Support/Claude/claude_desktop_config.json` on macOS, or `%APPDATA%\Claude\claude_desktop_config.json` on Windows):

```json
{
  "mcpServers": {
    "x-mcp": {
      "command": "xurl",
      "args": ["mcp", "https://api.x.com/mcp"],
      "startup_timeout_sec": 300
    }
  }
}
```

> The `startup_timeout_sec: 300` is recommended in the official X MCP docs to allow time for the initial OAuth flow if tokens need refreshing.

### Cursor

In Cursor, go to **Settings → MCP Servers** and add a new server with the command:

```
xurl mcp https://api.x.com/mcp
```

Refer to [Cursor's MCP documentation](https://www.cursor.com/docs) for the exact settings panel location in your version.

### Grok Build

Grok Build has native support for the X MCP server. In the Grok Build interface, select **Add MCP Server** and provide:

- **URL:** `https://api.x.com/mcp`
- **Auth:** OAuth (via xurl bridge)

Refer to the [official X MCP announcement](https://devcommunity.x.com/t/announcing-the-hosted-x-mcp/269558) for the exact Grok Build configuration snippet appropriate to your version.

### Other MCP Clients

For any MCP-compatible client, the connection pattern is consistent: run `xurl mcp https://api.x.com/mcp` as the bridge command. The specific configuration format varies by client — consult your client's MCP documentation.

---

## Step 5: Test the Connection

Once configured, restart your AI client and try a simple X-related prompt:

> "Search X for recent posts about agentic AI from the last 24 hours."

If connected correctly, your AI tool will use the X MCP server to fetch real results from the X API using your account's permissions.

---

## Optional: Connect the Docs MCP

For AI-assisted exploration of X's developer documentation, you can also add the Docs MCP server. It's a hosted read-only server at `https://docs.x.com/mcp` that doesn't require OAuth — your MCP client can connect directly.

Consult the [official X MCP documentation](https://docs.x.com/tools/mcp) for the direct connection configuration for your specific client.

---

## Troubleshooting

**Authentication errors:** Re-run `xurl auth oauth2` to refresh your tokens. Ensure your X app has the correct redirect URI registered in the Developer Portal.

**Timeout on startup:** The `startup_timeout_sec: 300` setting in your config gives the OAuth flow enough time. Don't reduce this on first setup.

**Read-only vs. write access:** Full write access (bookmarks, Articles, posting) requires user-context OAuth with the appropriate scopes. Read-only search and timeline access can use app-only Bearer token mode. Check which scopes your X app has enabled.

**Commands not working:** Verify you're running `xurl` from the command line and it's correctly installed. Run `xurl --help` to confirm installation.
