X MCP Server - Enhanced Edition

An enhanced Model Context Protocol (MCP) server for X that adds OAuth 2.0 support, v2 API media uploads, and comprehensive rate limiting to the original implementation.

✨ Features

• Post Tweets: Create text tweets with optional media attachments (images, GIFs)
• Search Tweets: Search X with customizable result count
• Delete Tweets: Remove your tweets programmatically
• Dual Authentication: Support for both OAuth 1.0a and OAuth 2.0
• Media Upload: Post images using the appropriate API version for each auth method
• Rate Limiting: Built-in protection for X's API limits
• Type Safety: Full TypeScript implementation with Zod validation

🔄 API Version Handling

This server intelligently uses different X API versions based on authentication method and operation:

OAuth 1.0a

• Tweet operations: Uses v2 API endpoints
• Media upload: Uses v1.1 endpoint (upload.twitter.com)
• Delete fallback: Automatically falls back to v1.1 when v2 fails

OAuth 2.0

• All operations: Uses v2 API endpoints exclusively
• Media upload: Uses v2 endpoint (api.x.com/2/media/upload)
• No v1.1 access: Cannot fall back to v1.1 due to authentication restrictions

Why Different Endpoints?

• v1.1: Legacy API, being phased out but still works with OAuth 1.0a
• v2: Modern API with better features but some endpoints have issues
• Media: OAuth 2.0 tokens cannot access v1.1 media endpoints, must use v2
• Delete: v2 delete endpoint currently has issues (500 errors), v1.1 works as fallback

📋 Prerequisites

Before you begin, you'll need:

1. An X Developer Account (sign up at developer.x.com)
2. An X App created in the Developer Portal
3. API credentials (detailed setup below)
4. Node.js 18+ installed

🔐 Authentication Setup

This server supports two authentication methods. Choose based on your needs:

• OAuth 1.0a: Simpler setup, works with all features including v1.1 fallbacks
• OAuth 2.0: Modern authentication, required for some newer features

Setting Up Your X App

1. Create a Developer Account:

   • Go to developer.x.com
   • Sign in with your Twitter account
   • Apply for developer access if you haven't already

2. Create a New App:

   • Navigate to the Twitter Developer Portal
   • Click "Projects & Apps" → "New Project"
   • Give your project a name
   • Select your use case
   • Create a new App within the project

3. Configure App Permissions:

   • In your app settings, go to "User authentication settings"
   • Click "Set up"
   • Enable OAuth 1.0a and/or OAuth 2.0
   • Set App permissions to "Read and write"
   • Add Callback URLs:
     • For OAuth 1.0a: http://localhost:3000/callback
     • For OAuth 2.0: http://localhost:3000/callback
   • Set Website URL (can be your GitHub repo)

OAuth 1.0a Setup

1. Get Your Credentials:

   • In your app's "Keys and tokens" tab
   • Copy your API Key and API Key Secret
   • Generate Access Token and Secret (click "Generate")
   • Make sure the access token has "Read and Write" permissions

2. Required Credentials:

   API_KEY=your_api_key_here
   API_SECRET_KEY=your_api_secret_key_here
   ACCESS_TOKEN=your_access_token_here
   ACCESS_TOKEN_SECRET=your_access_token_secret_here
   

OAuth 2.0 Setup

1. Get Your Client Credentials:

   • In your app's "Keys and tokens" tab
   • Find OAuth 2.0 Client ID and Client Secret
   • Save these for the next step

2. Generate User Tokens:

   Option A - Use our helper script:

   # Clone this repository first
   git clone https://github.com/mbelinky/x-mcp-server.git
   cd x-mcp-server/twitter-mcp
   npm install
   
   # Run the OAuth2 setup script
   node scripts/oauth2-setup.js
   

   Option B - Manual setup:

   • Use the OAuth 2.0 flow with PKCE
   • Required scopes: tweet.read, tweet.write, users.read, media.write, offline.access
   • Exchange authorization code for access token

3. Required Credentials:

   AUTH_TYPE=oauth2
   OAUTH2_CLIENT_ID=your_client_id_here
   OAUTH2_CLIENT_SECRET=your_client_secret_here
   OAUTH2_ACCESS_TOKEN=your_access_token_here
   OAUTH2_REFRESH_TOKEN=your_refresh_token_here

3. Restart Claude Desktop

For Claude Code (CLI)

Install the server globally and add it to Claude:

# For OAuth 1.0a
claude mcp add twitter-mcp "npx" "-y" "@mbelinky/x-mcp-server" --scope user \
  --env "API_KEY=your_api_key" \
  --env "API_SECRET_KEY=your_secret_key" \
  --env "ACCESS_TOKEN=your_access_token" \
  --env "ACCESS_TOKEN_SECRET=your_access_token_secret"

# For OAuth 2.0
claude mcp add twitter-mcp "npx" "-y" "@mbelinky/x-mcp-server" --scope user \
  --env "AUTH_TYPE=oauth2" \
  --env "OAUTH2_CLIENT_ID=your_client_id" \
  --env "OAUTH2_CLIENT_SECRET=your_client_secret" \
  --env "OAUTH2_ACCESS_TOKEN=your_access_token" \
  --env "OAUTH2_REFRESH_TOKEN=your_refresh_token"

🛠️ Available Tools

Once installed, Claude can use these tools:

post_tweet

Post a new tweet with optional media attachments and replies.

Example prompts:

• "Post a tweet saying 'Hello from Claude!'"
• "Tweet this image with the caption 'Check out this view!'" (attach image)
• "Reply to tweet ID 123456789 with 'Great point!'"

search_tweets

Search for tweets with customizable result count (10-100).

Example prompts:

• "Search for tweets about #MachineLearning"
• "Find 50 recent tweets mentioning @ClaudeAI"
• "Search for tweets about TypeScript tutorials"

delete_tweet

Delete a tweet by its ID.

Example prompts:

• "Delete tweet with ID 1234567890"
• "Remove my last tweet (provide the ID)"

Note: Due to temporary Twitter API issues, OAuth 1.0a uses v1.1 fallback for deletion.

📸 Media Upload Notes

When using Claude to post tweets with images:

• Use file paths: Save your image to disk and provide the file path
• Base64 limitation: While the server supports base64 encoded images, Claude cannot extract base64 from pasted images
• Other clients: Base64 support remains available for programmatic use and other MCP clients

Example usage:

# ✅ Recommended for Claude
"Post tweet with image at /Users/me/photos/sunset.png"

# ❌ Not currently supported in Claude
"Post this image: [pasting an image directly]"

# ✅ Works programmatically
// In code, you can still use base64
{
  "text": "Hello world!",
  "media": [{
    "data": "iVBORw0KGgoAAAANS...",
    "media_type": "image/png"
  }]
}

✅ OAuth 2.0 Media Upload Support

Media uploads now work with both OAuth 1.0a and OAuth 2.0!

• OAuth 1.0a uses the v1.1 media upload endpoint ✓
• OAuth 2.0 uses the v2 media upload endpoint ✓
• Both authentication methods support posting tweets with images (JPEG, PNG, GIF)

Note: OAuth 2.0 requires the media.write scope for media uploads.

⚠️ Known Issues

Tweet Deletion (Temporary)

Twitter's v2 delete endpoint is currently experiencing issues (returning 500 errors). The MCP server handles this gracefully:

• OAuth 1.0a: Automatically falls back to v1.1 delete endpoint ✅
• OAuth 2.0: Cannot use v1.1 endpoint, will show helpful error message ⚠️

This is a temporary Twitter API issue. Once resolved, both auth methods will use v2 deletion.

🐛 Troubleshooting

Common Issues

"Could not authenticate you"

• Verify all credentials are correct
• Check that your app has "Read and Write" permissions
• For OAuth 1.0a, regenerate your access tokens
• For OAuth 2.0, ensure tokens have required scopes

"Rate limit exceeded"

• Twitter has strict rate limits (especially on free tier)
• Wait 15 minutes and try again
• Consider upgrading your Twitter API access level

"Media upload failed"

• Check file size (max 5MB for images)
• Verify file format (JPEG, PNG, GIF only)
• For OAuth 2.0, ensure media.write scope is included

"403 Forbidden"

• Your app may lack required permissions
• Check your Twitter Developer Portal settings
• Ensure your access level supports the operation

Debug Mode

Enable detailed logging by setting the DEBUG environment variable:

{
  "env": {
    "DEBUG": "true",
    // ... other credentials
  }
}
