Twitch is one of the largest game streaming platforms in the world, and its chat system runs on the IRC (Internet Relay Chat) protocol. OpenClaw supports Twitch IRC channels through its plugin system, allowing you to deploy an AI chatbot in Twitch live chat rooms for automated Q&A, interactive entertainment, content moderation assistance, and more.
Prerequisites
Before getting started, you need the following:
- An OpenClaw instance deployed and running
- A Twitch account to serve as the Bot identity (it is recommended to create a dedicated Bot account rather than using the streamer's personal account)
- A Twitch OAuth Token (for Bot authentication)
- A list of channel names to join
Obtaining a Twitch OAuth Token
The Bot needs an OAuth token to authenticate with Twitch IRC. You can obtain one by registering an application through the Twitch Developer Portal.
First, visit dev.twitch.tv, log in with the Bot account, and create a new application. Note down the Client ID. Then, go through the OAuth authorization flow to obtain an access token. The required permission scopes include chat:read and chat:edit.
The resulting token will look something like oauth:xxxxxxxxxxxxxx and will be used in the configuration below.
Installing the Twitch IRC Plugin
Install via the OpenClaw plugin system:
openclaw plugin install twitch-irc
Configure using the interactive command:
openclaw channels login twitch-irc
The system will prompt you to enter the Bot username, OAuth Token, and the channel names to join.
Configuring openclaw.json
Manual configuration method:
{
"channels": {
"twitch-irc": {
"enabled": true,
"username": "your_bot_username",
"token": "oauth:xxxxxxxxxxxxxx",
"channels": ["channel1", "channel2"],
"commandPrefix": "!ask"
}
}
}
username is the Bot's Twitch username, token is the OAuth token, channels is the list of channels to join (without the # prefix), and commandPrefix is the command prefix that triggers AI replies.
Trigger Mechanisms
Twitch chat rooms typically have a high volume of messages, especially in popular streams. Having the AI respond to every message is neither practical nor appropriate. OpenClaw provides several trigger modes:
Command Prefix Mode: Only messages starting with the specified prefix will trigger an AI reply. For example, if commandPrefix is set to !ask, the user must send !ask What's the weather like today? to get a response. This is the most recommended mode.
Mention Mode: Triggers a reply when the chat message @mentions the Bot's username. Configure with "triggerMode": "mention".
Keyword Mode: Triggers when a message contains specific keywords. Configure with "triggerKeywords": ["keyword1", "keyword2"].
{
"channels": {
"twitch-irc": {
"triggerMode": "command",
"commandPrefix": "!ai"
}
}
}
Message Length Limits
Twitch IRC has a 500-character limit per message. If the AI reply exceeds this length, OpenClaw will automatically split the reply into multiple messages. You can also adjust this behavior in the configuration:
{
"channels": {
"twitch-irc": {
"maxMessageLength": 450,
"splitLongMessages": true
}
}
}
It is recommended to set maxMessageLength to slightly less than 500 to leave room for any prefix Twitch might add.
Rate Limiting
Twitch enforces strict rate limits on IRC message sending. Regular users can send a maximum of 20 messages per 30 seconds. This limit is relaxed once the Bot is verified as a "Known Bot." OpenClaw's Twitch plugin has built-in rate control logic that automatically queues and delays messages to avoid hitting the limits.
If your Bot needs to operate in high-traffic channels, it is recommended to apply for "Known Bot" status through the Twitch Developer Portal for a higher rate limit.
Security and Permissions
Use an allowlist to control which users can trigger AI replies:
{
"channels": {
"twitch-irc": {
"allowlist": ["user1", "user2"],
"moderatorsAllowed": true,
"subscribersOnly": false
}
}
}
When moderatorsAllowed is set to true, channel Moderators automatically receive permission to use the Bot. When subscribersOnly is set to true, only channel subscribers can use the AI features.
Multi-Channel and Coexistence
A single OpenClaw instance's Twitch Bot can join multiple channels simultaneously, with conversations in each channel handled independently. Additionally, the Twitch channel can coexist with other OpenClaw channels (such as Discord, Telegram, etc.), sharing the same AI backend. This is ideal for streamers or communities operating across multiple platforms.
Common Issues
If the Bot cannot connect to Twitch IRC, first check whether the OAuth Token is valid. Tokens may expire and need to be regenerated. If the Bot is connected but not responding to messages, verify that the trigger mode configuration is correct and that the Bot has actually joined the target channel. You can check the detailed IRC connection and message reception status in the OpenClaw logs.
