Common Patterns

Search with Filters

# High-engagement tweets in specific timeframe
search_twitter_advanced(
    query="AI",
    min_likes=1000,
    min_retweets=500,
    since="2024-01-01",
    until="2024-12-31",
    verified_only=True,
    language="en"
)

Monitor Multiple Accounts

# Add multiple KOLs to watch list
for username in ["elonmusk", "VitalikButerin", "naval"]:
    add_twitter_watch(
        username=username,
        event_types=["NEW_TWEET", "NEW_FOLLOWER"],
        remark=f"Tracking {username}"
    )

Track Engagement

# Get full engagement picture for a tweet
tweet = get_twitter_tweet_by_id(tweet_id="1234567890")
quotes = get_twitter_quote_tweets_by_id(tweet_id="1234567890")
retweet_users = get_twitter_retweet_users_by_id(tweet_id="1234567890")

Follower Analysis

# Compare followers vs KOL followers
all_followers = get_twitter_follower_events(
    username="elonmusk",
    event_type="NEW_FOLLOWER"
)
kol_followers = get_twitter_kol_followers(username="elonmusk")

Troubleshooting

Authentication Errors

• Verify TWITTER_TOKEN is set correctly
• Check token validity at https://6551.io/mcp
• Ensure no extra whitespace in token value

Rate Limiting

• Default max_rows is 100; reduce if hitting limits
• Space out requests when monitoring multiple accounts

Connection Issues

• Verify TWITTER_API_BASE if using custom endpoint
• Check firewall/proxy settings for ai.6551.io access
• For WebSocket: ensure WSS protocol is allowed

Empty Results

• Username lookup is case-insensitive but must be exact
• Some accounts may have restricted data access
• Recent tweets may take moments to appear in search

Tool Not Found

• Restart your AI client after config changes
• Verify uv is in PATH
• Check project path is absolute, not relative

Common Use Cases

Content Research: Search tweets with advanced filters to find trending topics, viral content, or specific conversations.

Influencer Monitoring: Track follower growth, engagement patterns, and deleted tweets for transparency.

Community Management: Monitor mentions, replies, and engagement on your own tweets or brand accounts.

Competitive Analysis: Track competitors' follower changes, KOL supporters, and content strategies.

Event Tracking: Set up watches for breaking news, product launches, or community events via real-time WebSocket feeds.
