Tlon is a decentralized messenger built on Urbit. OpenClaw connects to your Urbit ship and can respond to DMs and group chat messages. Group replies require an @ mention by default and can be further restricted via allowlists.

Status: supported via plugin. DMs, group mentions, thread replies, and text-only media fallback (URL appended to caption). Reactions, polls, and native media uploads are not supported.

Tlon ships as a plugin and is not bundled with the core install.

Install via CLI (npm registry):

openclaw plugins install @openclaw/tlon

Local checkout (when running from a git repo):

openclaw plugins install ./extensions/tlon

Details: Plugins

1. Install the Tlon plugin.
2. Gather your ship URL and login code.
3. Configure channels.tlon.
4. Restart the gateway.
5. DM the bot or mention it in a group channel.

Minimal config (single account):

{
  channels: {
    tlon: {
      enabled: true,
      ship: "~sampel-palnet",
      url: "https://your-ship-host",
      code: "lidlut-tabwed-pillex-ridrup"
    }
  }
}

Auto-discovery is enabled by default. You can also pin channels manually:

{
  channels: {
    tlon: {
      groupChannels: [
        "chat/~host-ship/general",
        "chat/~host-ship/support"
      ]
    }
  }
}

Disable auto-discovery:

{
  channels: {
    tlon: {
      autoDiscoverChannels: false
    }
  }
}

DM allowlist (empty = allow all):

{
  channels: {
    tlon: {
      dmAllowlist: ["~zod", "~nec"]
    }
  }
}

Group authorization (restricted by default):

{
  channels: {
    tlon: {
      defaultAuthorizedShips: ["~zod"],
      authorization: {
        channelRules: {
          "chat/~host-ship/general": {
            mode: "restricted",
            allowedShips: ["~zod", "~nec"]
          },
          "chat/~host-ship/announcements": {
            mode: "open"
          }
        }
      }
    }
  }
}

Use these with openclaw message send or cron delivery:

• DM: ~sampel-palnet or dm/~sampel-palnet
• Group: chat/~host-ship/channel or group:~host-ship/channel

• Group replies require a mention (e.g. ~your-bot-ship) to respond.
• Thread replies: if the inbound message is in a thread, OpenClaw replies in-thread.
• Media: sendMedia falls back to text + URL (no native upload).
