💻 Usage Examples

Available Tools

Chat Interaction

• sendMessageToChat: Send a message to Twitch chat.
• getRecentChatLog: Get the last 20 chat messages for context.
• analyzeChat: Analyze chat for topics and activity.

Stream Management

• createTwitchPoll: Create a poll with multiple choices.
• createTwitchPrediction: Create a prediction with outcomes.
• createTwitchClip: Create a clip of the current stream.
• updateStreamTitle: Change the stream title.
• updateStreamCategory: Change the game/category.

Moderation

• timeoutUser: Timeout a user for a specified duration.
• banUser: Permanently ban a user from chat.

Advanced Features

Smart User Resolution

When performing moderation actions, you can provide either:

1. An exact username.
2. A behavioral descriptor (e.g., "toxic", "spam").
3. A partial username match.

The server will attempt to resolve the appropriate user based on chat history.

Intelligent Timeout Duration

The timeout tool automatically suggests an appropriate duration based on the severity of the provided reason:

• Spam/excessive emotes: 5 minutes.
• Toxic behavior: 30 minutes.
• Severe violations: 60 minutes.
• Other violations: 10 minutes (default).

🔧 Technical Details

Image Description Support

While AI assistants (like Cursor/Claude) can process and describe images, there are some considerations when using this with the Twitch MCP server:

• Image processing: Image analysis is handled by the AI client, not the MCP server itself.
• Message length: AI-generated descriptions can be quite long. Twitch chat has a 500 character limit per message.
• Auto-truncation: The sendMessageToChat tool now automatically truncates messages that exceed 500 characters and notifies you when this happens.
• Workaround: For detailed image descriptions, consider asking the AI to provide a shorter summary suitable for chat.

Other Considerations

• API Rate Limits: Twitch API has rate limits that may affect rapid successive calls.
• Permissions: Ensure your Twitch token has the necessary scopes for all desired features.
• Stream Status: Some tools (like creating clips) require an active stream.
