Twitch MCP Server

A comprehensive Twitch MCP (Model Context Protocol) server providing chat moderation, stream management, and Twitch API integration for AI systems.

For Streamers

• Use this server via Smithery → Cursor (no local install needed)
• Quick setup guide: video-guide/final-setup-guide.md
• Smithery server page (Playground + one‑click add to Cursor): https://smithery.ai/server/@Eclipse-XV/twitch-mcp-smithery
• Recommended first tests:
  • "Send a message to chat: Hello from MCP!"
  • "Create a poll titled 'Which map?' with choices 'A, B' for 60 seconds"

Note: Actions run as your broadcaster account. Test in Smithery Playground first, then use the Connect section to one‑click add to Cursor and approve.

Overview

This MCP server allows AI agents to interact with Twitch streams through a standardized set of tools. It supports:

• Sending messages to chat
• Creating polls and predictions
• Generating clips
• Analyzing chat for trends and topics
• Moderating chat (timeout/ban users)
• Updating stream title and category

Getting Started

Prerequisites

• Node.js 18+ installed
• Twitch API credentials (Client ID and OAuth token)
• Twitch channel with appropriate permissions

Installation

1. Clone this repository
2. Install dependencies:

   npm install
   

Configuration

You need to provide Twitch API credentials when connecting to the server. The following configuration options are required:

Deployment on Smithery

This server is configured for easy deployment on Smithery.

1. Push this repository to GitHub
2. Connect your GitHub account to Smithery
3. Create a new deployment, selecting this repository
4. Configure your Twitch API credentials in the Smithery dashboard

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)

Known Issues & Limitations

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
