IRC
Use IRC when you want OpenClaw in classic channels (#room) and direct messages.
IRC ships as an extension plugin, but it is configured in the main config under channels.irc.
Quick start
- Enable IRC config in
~/.openclaw/openclaw.json.
- Set at least:
{
channels: {
irc: {
enabled: true,
host: "irc.libera.chat",
port: 6697,
tls: true,
nick: "openclaw-bot",
channels: ["#openclaw"],
},
},
}
- Start/restart gateway:
Security defaults
channels.irc.dmPolicy defaults to "pairing".
channels.irc.groupPolicy defaults to "allowlist".
- With
groupPolicy="allowlist", set channels.irc.groups to define allowed channels.
- Use TLS (
channels.irc.tls=true) unless you intentionally accept plaintext transport.
Access control
There are two separate “gates” for IRC channels:
- Channel access (
groupPolicy + groups): whether the bot accepts messages from a channel at all.
- Sender access (
groupAllowFrom / per-channel groups["#channel"].allowFrom): who is allowed to trigger the bot inside that channel.
Config keys:
- DM allowlist (DM sender access):
channels.irc.allowFrom
- Group sender allowlist (channel sender access):
channels.irc.groupAllowFrom
- Per-channel controls (channel + sender + mention rules):
channels.irc.groups["#channel"]
channels.irc.groupPolicy="open" allows unconfigured channels (still mention-gated by default)
Allowlist entries should use stable sender identities (nick!user@host).
Bare nick matching is mutable and only enabled when channels.irc.dangerouslyAllowNameMatching: true.
Common gotcha: allowFrom is for DMs, not channels
If you see logs like:
irc: drop group sender alice!ident@host (policy=allowlist)
…it means the sender wasn’t allowed for group/channel messages. Fix it by either:
- setting
channels.irc.groupAllowFrom (global for all channels), or
- setting per-channel sender allowlists:
channels.irc.groups["#channel"].allowFrom
Example (allow anyone in #tuirc-dev to talk to the bot):
{
channels: {
irc: {
groupPolicy: "allowlist",
groups: {
"#tuirc-dev": { allowFrom: ["*"] },
},
},
},
}
Reply triggering (mentions)
Even if a channel is allowed (via groupPolicy + groups) and the sender is allowed, OpenClaw defaults to mention-gating in group contexts.
That means you may see logs like drop channel … (missing-mention) unless the message includes a mention pattern that matches the bot.
To make the bot reply in an IRC channel without needing a mention, disable mention gating for that channel:
{
channels: {
irc: {
groupPolicy: "allowlist",
groups: {
"#tuirc-dev": {
requireMention: false,
allowFrom: ["*"],
},
},
},
},
}
Or to allow all IRC channels (no per-channel allowlist) and still reply without mentions:
{
channels: {
irc: {
groupPolicy: "open",
groups: {
"*": { requireMention: false, allowFrom: ["*"] },
},
},
},
}
Security note (recommended for public channels)
If you allow allowFrom: ["*"] in a public channel, anyone can prompt the bot.
To reduce risk, restrict tools for that channel.
{
channels: {
irc: {
groups: {
"#tuirc-dev": {
allowFrom: ["*"],
tools: {
deny: ["group:runtime", "group:fs", "gateway", "nodes", "cron", "browser"],
},
},
},
},
},
}
Use toolsBySender to apply a stricter policy to "*" and a looser one to your nick:
{
channels: {
irc: {
groups: {
"#tuirc-dev": {
allowFrom: ["*"],
toolsBySender: {
"*": {
deny: ["group:runtime", "group:fs", "gateway", "nodes", "cron", "browser"],
},
"id:eigen": {
deny: ["gateway", "nodes", "cron"],
},
},
},
},
},
},
}
Notes:
toolsBySender keys should use id: for IRC sender identity values:
id:eigen or id:eigen!~eigen@174.127.248.171 for stronger matching.
- Legacy unprefixed keys are still accepted and matched as
id: only.
- The first matching sender policy wins;
"*" is the wildcard fallback.
For more on group access vs mention-gating (and how they interact), see: /channels/groups.
NickServ
To identify with NickServ after connect:
{
channels: {
irc: {
nickserv: {
enabled: true,
service: "NickServ",
password: "your-nickserv-password",
},
},
},
}
Optional one-time registration on connect:
{
channels: {
irc: {
nickserv: {
register: true,
registerEmail: "bot@example.com",
},
},
},
}
Disable register after the nick is registered to avoid repeated REGISTER attempts.
Environment variables
Default account supports:
IRC_HOST
IRC_PORT
IRC_TLS
IRC_NICK
IRC_USERNAME
IRC_REALNAME
IRC_PASSWORD
IRC_CHANNELS (comma-separated)
IRC_NICKSERV_PASSWORD
IRC_NICKSERV_REGISTER_EMAIL
Troubleshooting
- If the bot connects but never replies in channels, verify
channels.irc.groups and whether mention-gating is dropping messages (missing-mention). If you want it to reply without pings, set requireMention:false for the channel.
- If login fails, verify nick availability and server password.
- If TLS fails on a custom network, verify host/port and certificate setup.
