X-MCP 2.0

MCP server for the X/Twitter API v2 with OAuth 2.0 PKCE authentication.

Use Claude to post tweets, search X, like, retweet, and more — with modern OAuth 2.0.

Why 2.0?

The original twitter-mcp uses OAuth 1.0a, which requires 4 separate keys and doesn't support newer API features. X-MCP 2.0 uses OAuth 2.0 with PKCE, the recommended auth method for Twitter API v2.

Tools (10)

Setup

1. Get Twitter API Credentials

1. Go to developer.x.com and create an app

2. Under Keys and Tokens, find OAuth 2.0 Client ID and Client Secret

3. Under User authentication settings, click Set up:

   • App permissions: Read and write

   • Type of App: Web App, Automated App or Bot

   • Callback URI: http://127.0.0.1:8739/callback

   • Website URL: your website or GitHub profile

2. Authorize (One-Time)

git clone https://github.com/JFan5/X-MCP-2.0.git
cd X-MCP-2.0
npm install

# Run the auth flow — opens browser for Twitter login
CLIENT_ID=your_client_id CLIENT_SECRET=your_client_secret npm run auth

This saves tokens to ~/.x-mcp-tokens.json and prints the ACCESS_TOKEN and REFRESH_TOKEN.

3. Configure Claude

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "x-mcp": {
      "command": "node",
      "args": ["/path/to/X-MCP-2.0/dist/index.js"],
      "env": {
        "CLIENT_ID": "your_client_id",
        "CLIENT_SECRET": "your_client_secret",
        "ACCESS_TOKEN": "your_access_token",
        "REFRESH_TOKEN": "your_refresh_token"
      }
    }
  }
}

Or for Claude Code, add to ~/.claude/settings.json:

{
  "mcpServers": {
    "x-mcp": {
      "command": "node",
      "args": ["/path/to/X-MCP-2.0/dist/index.js"],
      "env": {
        "CLIENT_ID": "your_client_id",
        "CLIENT_SECRET": "your_client_secret",
        "ACCESS_TOKEN": "your_access_token",
        "REFRESH_TOKEN": "your_refresh_token"
      }
    }
  }
}

4. Build (if running from source)

npm run build

Token Refresh

If you included the REFRESH_TOKEN, X-MCP 2.0 automatically refreshes your access token when it expires (every 2 hours). No manual intervention needed.

Examples

Ask Claude:

• "Post a tweet about my new open-source project"

• "Search for tweets about GRPO reinforcement learning"

• "What's on my Twitter timeline?"

• "Like the top tweet about machine learning"

• "Show me @kaboroevich's recent tweets"
