Tlon (plugin)

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, rich text formatting, and image uploads are supported. Reactions and polls are not yet supported.

Plugin required

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

Setup

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",
      ownerShip: "~your-main-ship", // recommended: your ship, always allowed
    },
  },
}

Private/LAN ships

By default, OpenClaw blocks private/internal hostnames and IP ranges for SSRF protection. If your ship is running on a private network (localhost, LAN IP, or internal hostname), you must explicitly opt in:

{
  channels: {
    tlon: {
      url: "http://localhost:8080",
      allowPrivateNetwork: true,
    },
  },
}

This applies to URLs like:

• http://localhost:8080
• http://192.168.x.x:8080
• http://my-ship.local:8080

⚠️ Only enable this if you trust your local network. This setting disables SSRF protections for requests to your ship URL.

Group channels

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,
    },
  },
}

Access control

DM allowlist (empty = no DMs allowed, use ownerShip for approval flow):

{
  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",
          },
        },
      },
    },
  },
}

Owner and approval system

Set an owner ship to receive approval requests when unauthorized users try to interact:

{
  channels: {
    tlon: {
      ownerShip: "~your-main-ship",
    },
  },
}

The owner ship is automatically authorized everywhere — DM invites are auto-accepted and channel messages are always allowed. You don't need to add the owner to dmAllowlist or defaultAuthorizedShips.

When set, the owner receives DM notifications for:

• DM requests from ships not in the allowlist
• Mentions in channels without authorization
• Group invite requests

Auto-accept settings

Auto-accept DM invites (for ships in dmAllowlist):

{
  channels: {
    tlon: {
      autoAcceptDmInvites: true,
    },
  },
}

Auto-accept group invites:

{
  channels: {
    tlon: {
      autoAcceptGroupInvites: true,
    },
  },
}

Delivery targets (CLI/cron)

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

Bundled skill

The Tlon plugin includes a bundled skill (@tloncorp/tlon-skill) that provides CLI access to Tlon operations:

• Contacts: get/update profiles, list contacts
• Channels: list, create, post messages, fetch history
• Groups: list, create, manage members
• DMs: send messages, react to messages
• Reactions: add/remove emoji reactions to posts and DMs
• Settings: manage plugin permissions via slash commands

The skill is automatically available when the plugin is installed.

Capabilities

Troubleshooting

Run this ladder first:

openclaw status
openclaw gateway status
openclaw logs --follow
openclaw doctor

Common failures:

• DMs ignored: sender not in dmAllowlist and no ownerShip configured for approval flow.
• Group messages ignored: channel not discovered or sender not authorized.
• Connection errors: check ship URL is reachable; enable allowPrivateNetwork for local ships.
• Auth errors: verify login code is current (codes rotate).

Configuration reference

Full configuration: Configuration

Provider options:

• channels.tlon.enabled: enable/disable channel startup.
• channels.tlon.ship: bot's Urbit ship name (e.g. ~sampel-palnet).
• channels.tlon.url: ship URL (e.g. https://sampel-palnet.tlon.network).
• channels.tlon.code: ship login code.
• channels.tlon.allowPrivateNetwork: allow localhost/LAN URLs (SSRF bypass).
• channels.tlon.ownerShip: owner ship for approval system (always authorized).
• channels.tlon.dmAllowlist: ships allowed to DM (empty = none).
• channels.tlon.autoAcceptDmInvites: auto-accept DMs from allowlisted ships.
• channels.tlon.autoAcceptGroupInvites: auto-accept all group invites.
• channels.tlon.autoDiscoverChannels: auto-discover group channels (default: true).

Notes

• 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.
• Rich text: Markdown formatting (bold, italic, code, headers, lists) is converted to Tlon's native format.
• Images: URLs are uploaded to Tlon storage and embedded as image blocks.
