Mattermost Plugin

Overview

OpenClaw integrates with Mattermost, a self-hostable team messaging platform, via a plugin.

Installation

The plugin requires separate installation:

openclaw plugins install @openclaw/mattermost

Core Configuration

The minimal setup requires three elements:

A bot token
Base URL
A DM policy

Mattermost responds to DMs automatically, with channel interactions governed by the chatmode setting.

Chat Modes

Three response patterns are available:

oncall (default): responds only to @mentions
onmessage: replies to all channel messages
onchar: triggers on specific prefix characters like > or !

Access Controls

DM Security

Uses a pairing code system by default, allowing administrators to approve unknown senders.

Channel Access

Controlled via allowlists using the groupAllowPolicy setting.

Multi-Account Support

Multiple Mattermost instances can be configured simultaneously under separate account identifiers, each with independent tokens and base URLs.

Message Delivery Targets

Outbound messages use standardized formats:

channel:<id> - Channel messages
user:<id> - Direct messages by user ID
@username - Direct messages by username

Environment Variables

Environment variable alternatives are available for the default account configuration.

Troubleshooting

Common issues involve:

Channel visibility
Authentication issues
