dvcrn PrivateBridge
Enables secure remote communication between an OpenClaw instance and a relay server without exposing ports, requiring SSH, or relying on Telegram/Discord.
Description
The PrivateBridge skill registers your local OpenClaw instance as a managed remote node on a relay network. Once connected, the node can receive prompts, execute workflows, report health, and be restarted — all through a secure, outbound-only WebSocket channel.
This skill replaces external messaging-based control layers such as Telegram or Discord with a native, secure relay channel for OpenClaw interaction.
Node Lifecycle
When the skill is enabled, the OpenClaw instance registers as a remote-capable node with the relay and maintains an active session.
The node can be in one of three states:
| State | Description |
|---|---|
| Online | Authenticated and accepting relay commands |
| Reconnecting | Connection lost; auto-reconnecting with exponential backoff |
| Offline | Skill disabled or relay unreachable after max retries |
Relay commands are only accepted while the node is authenticated and online. Commands received during reconnection are discarded by the relay.
Capabilities
| Capability | Description |
|---|---|
remote_chat |
Receive and execute prompts remotely, streaming tokens back in real time |
remote_status |
Report node health: uptime, active tasks, last error, connection state |
remote_restart |
Safely restart the OpenClaw process without manual intervention. Pending executions are cancelled and reported before restart occurs. |
remote_trigger |
Execute OpenClaw workflows/tasks triggered remotely |
Remote commands are limited to declared capabilities and cannot execute arbitrary system-level operations.
Configuration
| Key | Required | Description |
|---|---|---|
relay_url |
✅ | WebSocket URL of the relay server |
node_id |
✅ | Unique identifier for this OpenClaw node |
auth_token |
✅ | Secret token for authenticating with the relay |
Message Protocol
Incoming (Relay → Node)
type |
Action |
|---|---|
prompt |
Execute via OpenClaw prompt runner, stream response tokens back |
status |
Return node health payload |
restart |
Cancel pending tasks, report them, then gracefully restart |
workflow |
Execute a named OpenClaw task/workflow |
Outgoing (Node → Relay)
- Heartbeat (every 15s):
{ "node_id": "...", "uptime": 3600, "active_tasks": 2, "last_error": null, "connection_state": "online" } - Response stream:
{ "type": "token", "request_id": "...", "content": "..." }per token - Response complete:
{ "type": "done", "request_id": "..." } - Status: Full heartbeat payload with
request_id
External Endpoints
| Endpoint | Protocol | Data Sent | Data Received |
|---|---|---|---|
wss://<relay_url>/connect |
WebSocket (TLS) | auth_token, node_id, heartbeat payloads, prompt response tokens |
Relay commands: prompt, status, restart, workflow |
No other external endpoints are contacted. All network activity is limited to the configured relay_url.
Security & Privacy
What leaves your machine
auth_token— sent once during the WebSocket handshake to authenticate the nodenode_id— sent with every heartbeat and response to identify the node- Heartbeat data — uptime (seconds), active task count, last error string, connection state
- Prompt response tokens — streamed back to the relay in response to
promptcommands - Workflow completion status — success/error for triggered workflows
What stays on your machine
- All local AI model execution and inference
- Local file system contents — never read or transmitted
- Environment variables (other than the three declared above)
- System information, IP addresses, or hardware details — never collected
Network posture
- Outbound only — the skill never opens a listening port or accepts inbound connections
- TLS encrypted — all WebSocket connections use
wss://(TLS 1.2+) - No data persistence — the relay server does not store prompt content or response tokens; it forwards in real time
Trust Statement
By installing this skill, you are connecting your OpenClaw instance to an external relay server at the configured
relay_url. Prompt content and response tokens are transmitted through this relay in real time. Only install this skill if you trust the operator of the relay server. The default relay (wss://relay-terminal-cloud.fly.dev) is operated by the project maintainers.
Operational Guarantees
- Local AI execution continues even if the relay disconnects
- Relay does not expose the node to inbound traffic
- Remote actions are capability-scoped — only declared capabilities can be invoked
- Pending tasks are reported before any restart occurs — no silent failures
Installation
Easiest way — use the visual setup wizard:
👉 Open your dashboard and go to /skill/remote-relay to configure everything through the UI — generate a node ID, test your connection, and export your config in one place.
Or configure manually:
- Add the skill to your OpenClaw instance
- Configure
relay_url,node_id, andauth_token - Start OpenClaw — the relay connection is established automatically
Intended Use
This skill replaces external messaging-based control layers such as Telegram or Discord with a native, secure relay channel for OpenClaw interaction. It is designed for teams and individuals who need reliable remote access to their OpenClaw nodes without exposing infrastructure.
