Mattermost bot setup and Clawdbot config	Setting up Mattermost Debugging Mattermost routing

Mattermost

Quick setup

1. Create a Mattermost bot account and copy the bot token.
2. Copy the Mattermost base URL (e.g., https://chat.example.com).
3. Configure Clawdbot and start the gateway.

Minimal config:

{
  channels: {
    mattermost: {
      enabled: true,
      botToken: "mm-token",
      baseUrl: "https://chat.example.com"
    }
  }
}

Environment variables (default account)

Set these on the gateway host if you prefer env vars:

• MATTERMOST_BOT_TOKEN=...
• MATTERMOST_URL=https://chat.example.com

Env vars apply only to the default account (default). Other accounts must use config values.

Chat modes

Mattermost responds to DMs automatically. Channel behavior is controlled by chatmode:

• oncall (default): respond only when @mentioned in channels.
• onmessage: respond to every channel message.
• onchar: respond when a message starts with a trigger prefix.

Config example:

{
  channels: {
    mattermost: {
      chatmode: "onchar",
      oncharPrefixes: [">", "!"]
    }
  }
}

Notes:

• onchar still responds to explicit @mentions.
• channels.mattermost.requireMention is honored for legacy configs but chatmode is preferred.

Targets for outbound delivery

Use these target formats with clawdbot message send or cron/webhooks:

• channel:<id> for a channel
• user:<id> for a DM
• @username for a DM (resolved via the Mattermost API)

Bare IDs are treated as channels.

Multi-account

Mattermost supports multiple accounts under channels.mattermost.accounts:

{
  channels: {
    mattermost: {
      accounts: {
        default: { name: "Primary", botToken: "mm-token", baseUrl: "https://chat.example.com" },
        alerts: { name: "Alerts", botToken: "mm-token-2", baseUrl: "https://alerts.example.com" }
      }
    }
  }
}

Troubleshooting

• No replies in channels: ensure the bot is in the channel and mention it (oncall), use a trigger prefix (onchar), or set chatmode: "onmessage".
• Auth errors: check the bot token, base URL, and whether the account is enabled.
• Multi-account issues: env vars only apply to the default account.
