# 401 Unauthorized Error Fix Verification ## Fix Summary ### 1. Dual Authentication System - ✅ Added OAuth 2.0 support (via TWITTER_BEARER_TOKEN) - ✅ Retained OAuth 1.0a support (for write operations) - ✅ Implemented smart client selection mechanism ### 2. Client Selection Logic ```python def get_read_client(): """Read operations prefer OAuth 2.0, fallback to OAuth 1.0a""" if oauth2_client: return oauth2_client return oauth1_client def get_write_client(): """Write operations always use OAuth 1.0a""" return oauth1_client ``` ### 3. Updated Functions - `handle_get_tweet()` - Uses `get_read_client()` - `handle_get_tweets()` - Uses `get_read_client()` - `handle_search_tweets()` - Uses `get_read_client()` - All write operations - Use `get_write_client()` ### 4. Enhanced Error Handling - Detailed English error messages - Specific solution suggestions - API connection testing tool ## Verification Steps ### 1. Configuration Verification Ensure your configuration includes: ```json { "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. Run Tests ```bash cd /path/to/x-mcp python test_tweet_functions.py ``` ### 3. Test in Claude ``` test api connection ``` ### 4. Test Tweet Retrieval ``` search for tweets containing "AI" get tweet 1234567890 content ``` ## Expected Results ### Success Case - OAuth 1.0a connection successful ✅ - OAuth 2.0 connection successful ✅ (if Bearer Token configured) - Read operations use OAuth 2.0 ✅ - Write operations use OAuth 1.0a ✅ - No more 401 Unauthorized errors ✅ ### Fallback Case If only OAuth 1.0a is configured: - System automatically uses OAuth 1.0a for all operations - Still more stable than before - Provides configuration recommendations ## Troubleshooting ### If 401 errors persist 1. Check API credentials are correct 2. Verify Twitter project permission settings 3. Regenerate API keys and tokens 4. Check network connectivity ### If OAuth 2.0 connection fails 1. Verify Bearer Token is correct 2. Check if Twitter project supports OAuth 2.0 3. Confirm API access level ## Technical Improvements ### 1. Code Structure - Clear client separation - Unified error handling - Better logging ### 2. User Experience - Automatic selection of best authentication method - Detailed error messages - Configuration validation and suggestions ### 3. Stability - Multiple authentication backup - Smart fallback handling - Better error recovery ## Testing Commands ### Basic Functionality Test ```bash # Test authentication python -c " from test_tweet_functions import * load_dotenv() if test_credentials(): oauth1 = test_oauth1_connection() oauth2 = test_oauth2_connection() print('OAuth 1.0a:', '✅' if oauth1 else '❌') print('OAuth 2.0:', '✅' if oauth2 else '❌') " ``` ### In Claude Desktop ``` test api connection search for tweets containing "hello world" get tweet 1234567890 content create draft tweet "Testing dual authentication system! 🚀" ``` ## Migration Guide ### From Single Authentication 1. **Backup existing configuration** 2. **Add Bearer Token to environment variables** 3. **Restart Claude Desktop** 4. **Test functionality** 5. **Verify improved stability** ### Configuration Comparison **Before (OAuth 1.0a only):** ```json { "env": { "TWITTER_API_KEY": "...", "TWITTER_API_SECRET": "...", "TWITTER_ACCESS_TOKEN": "...", "TWITTER_ACCESS_TOKEN_SECRET": "..." } } ``` **After (Dual Authentication):** ```json { "env": { "TWITTER_API_KEY": "...", "TWITTER_API_SECRET": "...", "TWITTER_ACCESS_TOKEN": "...", "TWITTER_ACCESS_TOKEN_SECRET": "...", "TWITTER_BEARER_TOKEN": "..." } } ``` This fix should resolve most 401 Unauthorized errors, especially for tweet retrieval functionality. The system is backward compatible and will work with existing OAuth 1.0a configurations while providing enhanced stability with dual authentication.
