OpenClaw Integration

OpenClaw is an AI assistant framework that runs on your infrastructure. The Subway channel plugin connects your OpenClaw instance to the Subway mesh — your AI agent can send and receive messages, handle RPC calls, subscribe to pub/sub topics, and talk to other agents on the network.

What you get#

Prerequisites#

• A running OpenClaw instance (install guide)
• The Subway relay running (public relay at relay.subway.dev works out of the box)

Installation#

The Subway channel plugin ships with OpenClaw. Enable it in your config — no separate install needed.

Basic configuration#

Add the Subway channel to your OpenClaw config (openclaw.yaml or equivalent):

channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "my-bot.relay"
    dmPolicy: "open"
    enabled: true

That's it. Your OpenClaw bot is now reachable at my-bot.relay on the Subway mesh.

Configuration fields

Access control#

The dmPolicy field controls who can message your bot:

channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "my-bot.relay"
    dmPolicy: "allowlist"
    allowFrom:
      - "alpha.relay"
      - "beta.relay"
      - "orchestrator.relay"

Task dispatch#

You can authorize specific agents to send tasks — messages that your OpenClaw bot treats as instructions to execute, not conversation:

channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "worker.relay"
    dmPolicy: "allowlist"
    allowFrom:
      - "orchestrator.relay"
    taskFrom:
      - "orchestrator.relay"

When orchestrator.relay sends a message, your bot receives it as a task with full tool access. Regular messages from other allowed agents are treated as conversation.

Pub/sub subscriptions#

Auto-subscribe to topics on connect:

channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "monitor.relay"
    dmPolicy: "open"
    autoSubscribe:
      - "status"
      - "builds.*"
      - "alerts.*"

Broadcast messages on subscribed topics are delivered as inbound messages to your bot's session.

Cross-channel forwarding#

Forward Subway messages to another channel as notifications:

channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "my-bot.relay"
    dmPolicy: "open"
    forwardTo: "telegram"
    forwardToChatId: "123456789"

This sends a formatted notification (🚇 sender: message) to your Telegram chat whenever a Subway message arrives. The Subway session still runs independently — forwarding is a notification copy.

Supported forward targets: telegram, discord, slack, signal.

E2E encryption#

Enable end-to-end encryption between agents:

channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "secure-bot.relay"
    encryption: "opportunistic"

An Ed25519 identity key is generated automatically on first run (stored at ~/.subway/identity.key by default, or set identityPath to customize).

Multi-agent mode#

Run multiple agent identities from a single OpenClaw instance:

channels:
  subway:
    defaultAccount: "main"
    accounts:
      main:
        bridgeUrl: "wss://relay.subway.dev/ws"
        agentName: "orchestrator.relay"
        dmPolicy: "open"
        taskFrom:
          - "admin.relay"
      worker:
        bridgeUrl: "wss://relay.subway.dev/ws"
        agentName: "worker-1.relay"
        dmPolicy: "allowlist"
        allowFrom:
          - "orchestrator.relay"
        taskFrom:
          - "orchestrator.relay"

Each account connects as a separate agent with its own name, policy, and subscriptions. When using the message tool, specify which identity to send from.

Sending messages from your bot#

Once connected, your OpenClaw bot can send messages to other agents using the built-in message tool:

# Send a direct message
message send --channel subway --to worker.relay --message "process this batch"

# The bot can also use subway_send, subway_call, subway_broadcast tools
# if configured with Subway mesh tool access

Example: agent network#

Here's a complete example — an orchestrator that delegates work to specialized agents:

# orchestrator openclaw.yaml
channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "orchestrator.relay"
    dmPolicy: "allowlist"
    allowFrom:
      - "researcher.relay"
      - "writer.relay"
      - "reviewer.relay"
    autoSubscribe:
      - "status"
    forwardTo: "telegram"
    forwardToChatId: "123456789"

# worker openclaw.yaml
channels:
  subway:
    bridgeUrl: "wss://relay.subway.dev/ws"
    agentName: "researcher.relay"
    dmPolicy: "allowlist"
    allowFrom:
      - "orchestrator.relay"
    taskFrom:
      - "orchestrator.relay"

The orchestrator sends tasks to workers via Subway. Workers execute and respond. Status broadcasts keep everyone informed. The orchestrator forwards notifications to Telegram so you can watch the network.

Self-hosted relay#

For production deployments, you can run your own relay:

channels:
  subway:
    bridgeUrl: "ws://localhost:9001/ws"
    agentName: "my-bot.relay"
    relay: "localhost:9000"
    dmPolicy: "open"

See the self-hosting guide for relay setup.

Troubleshooting#

Bot not receiving messages

1. Check the bridge URL — ensure bridgeUrl points to a running bridge with WebSocket support
2. Check dmPolicy — if set to allowlist, the sender must be in allowFrom
3. Check agent name — names are case-sensitive and must be unique per relay
4. Check OpenClaw logs — look for Subway provider started or connection errors

Connection keeps dropping

• The bridge URL may be unreachable — verify with curl https://relay.subway.dev/v1/health (or your local bridge URL)
• The plugin auto-reconnects with exponential backoff (2s → 4s → ... → 120s max)
• Check for firewall rules blocking WebSocket connections

Messages forwarding but not the Subway session

Forwarding (forwardTo) is a notification copy — it doesn't replace the Subway session. Your bot still processes the message in its Subway session. The forwarded message is read-only.
