Quick Setup

Installing via Smithery

To install X(Twitter) MCP Server for Claude code automatically via Smithery:

Manual Installation for Claude code

1. Clone the repository:

2. Install UV globally using Homebrew in Terminal:

3. Create claude_desktop_config.json:

   • For MacOS: Open directory ~/Library/Application Support/Claude/ and create the file inside it

   • For Windows: Open directory %APPDATA%/Claude/ and create the file inside it

4. Add this configuration to claude_desktop_config.json:

Basic Configuration (OAuth 1.0a Only)

Recommended Configuration (OAuth 1.0a + OAuth 2.0 Dual Authentication)

💡 Recommended to use dual authentication configuration: Adding TWITTER_BEARER_TOKEN can significantly improve the stability and success rate of tweet retrieval functions.

5. Get your X/Twitter API credentials:

   • Go to X API Developer Portal

   • Create a project

   • In User Authentication Settings: Set up with Read and Write permissions, Web App type

   • Set Callback URL to http://localhost/ and Website URL to http://example.com/

   • Generate and copy all keys and tokens from Keys and Tokens section

6. Update the config file:

   • Replace /path/to/x-mcp with your actual repository path

   • Add your X/Twitter API credentials

7. Quit Claude completely and reopen it

Configuration for Gemini CLI

If you want to use this MCP server with Gemini CLI instead of Claude code:

1. Install Gemini CLI:

2. Create or update your MCP configuration file:

   • Create a file named ~/.gemini/settings.json

   • Add the following configuration:

3. Start Gemini CLI with MCP support:

4. Update the config file:

   • Replace /path/to/x-mcp with your actual repository path

   • Add your X/Twitter API credentials

Advanced Configuration

Auto-Delete Failed Drafts

When tweet publishing fails, you can choose whether to automatically delete drafts:

• Enable auto-delete (default): Automatically delete drafts when publishing fails to avoid accumulating invalid drafts

• Disable auto-delete: Preserve drafts when publishing fails, allowing manual retry or modification

Configuration Methods

1. Via Environment Variable: Add "AUTO_DELETE_FAILED_DRAFTS": "true" or "false" in your configuration file

2. Via Commands: Use "Enable auto-delete failed drafts" or "Disable auto-delete failed drafts"

3. Check Status: Use "Check current auto-delete configuration"

Usage Examples

Works with both Claude code and Gemini CLI:

• "Tweet 'Just learned how to tweet through AI - mind blown! 🤖✨'"

• "Create a thread about the history of pizza"

• "Show me my draft tweets"

• "Publish this draft!"

• "Delete that draft"

• "Reply to tweet 1234567890 with 'Great point! Thanks for sharing.'"

Troubleshooting

Basic Issues

If not working:

• Make sure UV is installed globally (if not, uninstall with pip uninstall uv and reinstall with brew install uv)

• Or find UV path with which uv and replace "command": "uv" with the full path

• Verify all X/Twitter credentials are correct

• Check if the x-mcp path in config matches your actual repository location

🔧 API Connection Testing

Quick Diagnosis:

Running this command in Claude will:

• Test OAuth 1.0a and OAuth 2.0 connections

• Check API permissions and limitations

• Provide detailed diagnostic information and suggestions

Run Test Script:

🚨 401 Unauthorized Error Fix

Problem Symptoms:

• Getting "401 Unauthorized" error when posting tweets

• Can post tweets but cannot retrieve tweets

Solutions:

1. Add Bearer Token (Recommended):

   "env": { "TWITTER_API_KEY": "your_api_key", "TWITTER_API_SECRET": "your_api_secret", "TWITTER_ACCESS_TOKEN": "your_access_token", "TWITTER_ACCESS_TOKEN_SECRET": "your_access_token_secret", "TWITTER_BEARER_TOKEN": "your_bearer_token" }

2. Regenerate API Credentials:

   • Visit Twitter Developer Portal

   • Regenerate all API keys and tokens

   • Ensure permissions are set to "Read and write"

3. Check Project Settings:

   • User authentication settings: Read and write permissions

   • App type: Web App

   • Callback URL: http://localhost/

   • Website URL: http://example.com/

📖 Tweet Retrieval Issues

Dual Authentication Benefits:

• OAuth 2.0 for read operations (more stable)

• OAuth 1.0a for write operations (required)

• Automatic fallback handling

Common Errors and Solutions:

API Plan Limitations:

• Free Users: Basic functionality with limitations

• Basic ($100/month): Full read functionality

• Pro ($5000/month): Advanced features and higher limits

🔍 Detailed Diagnostic Steps

1. Check Authentication Status:

   test api connection

2. Verify Configuration:

   • Confirm all environment variables are set

   • Check paths are correct

   • Validate API key formats

3. Test Specific Functions:

   search for tweets containing "hello" get tweet 1234567890 content

4. Review Detailed Logs:

   • Check Claude Desktop console

   • Review MCP server logs

   • Note specific error messages
