Twitch MCP Server

AI-powered tools for Twitch streamers, exposed via the Model Context Protocol (MCP). Connect your coding/chat assistants (Gemini CLI, Qwen Coder, Claude Code, etc.) to your Twitch chat for moderation, stream management, and engagement.

Quick Start (No Cloning Required)

Prerequisites

Node.js 14+ and Java 11+ available on your system PATH
A Twitch account with appropriate API credentials

Setup Configuration

Create a config file with your Twitch credentials (use bare access token, no "oauth:" prefix):

Windows: C:/Users/<you>/AppData/Roaming/twitch-mcp/config.json
macOS: ~/Library/Application Support/twitch-mcp/config.json
Linux: ~/.config/twitch-mcp/config.json

Example config.json:

{
  "channel": "YOUR_TWITCH_USERNAME",
  "auth": "YOUR_TWITCH_ACCESS_TOKEN",  
  "clientId": "YOUR_TWITCH_CLIENT_ID",
  "broadcasterId": "YOUR_BROADCASTER_ID",
  "showConnectionMessage": true
}

Installation Options

Option 1: NPX (Recommended)

No installation required - your AI tool will automatically fetch the latest version:

npx twitch-mcp-server@latest --config /path/to/config.json

Option 2: Global Install

npm install -g twitch-mcp-server
twitch-mcp-server --config /path/to/config.json

Option 3: Local Development

See README-developers.md for building from source.

Usage Notes

Use a bare access token in auth field (no oauth: prefix needed)
Only one AI client should connect at a time to avoid conflicts
Ensure Node.js and Java are installed on the same system as your AI CLI
The server will automatically handle IRC formatting and API authentication

Troubleshooting

Authentication Issues:

Confirm auth is a bare token (no oauth: prefix)
Verify clientId and scopes match your generated token
Ensure broadcasterId matches your channel ID

Connection Problems:

Check that both Node.js and Java are in your system PATH
Try running java -version and node -version to verify installation
For Windows users: Make sure you're not running from WSL if your AI CLI is on Windows

NPX Prompts in Headless Environments:

The configurations above use -y flag for non-interactive execution
If you encounter prompts, add --yes to the npx command
