summary: "RPC adapters for external CLIs (signal-cli, imsg) and gateway patterns"

OpenClaw integrates external CLIs via JSON-RPC. Two patterns are used today.
|
|
|
|
## Pattern A: HTTP daemon (signal-cli)
|
|
|
|
- `signal-cli` runs as a daemon with JSON-RPC over HTTP.
|
|
- Event stream is SSE (`/api/v1/events`).
|
|
- Health probe: `/api/v1/check`.
|
|
- OpenClaw owns lifecycle when `channels.signal.transport.kind="managed-native"` (the default).
|
|
|
|
See [Signal](/channels/signal) for setup and endpoints.
|
|
|
|
## Pattern B: stdio child process (imsg)
|
|
|
|
- OpenClaw spawns `imsg rpc` as a child process for [iMessage](/channels/imessage).
|
|
- JSON-RPC is line-delimited over stdin/stdout (one JSON object per line).
|
|
- No TCP port, no daemon required.
|
|
|
|
Core methods used:
|
|
|
|
- `watch.subscribe` → notifications (`method: "message"`)
|
|
- `watch.unsubscribe`
|
|
- `send`
|
|
- `chats.list` (probe/diagnostics)
|
|
|
|
See [iMessage](/channels/imessage) for setup and addressing (`chat_id` preferred over display strings).
|
|
|
|
## Adapter guidelines
|
|
|
|
- Gateway owns the process (start/stop tied to provider lifecycle).
|
|
- Keep RPC clients resilient: timeouts, restart on exit.
|
|
- Prefer stable IDs (e.g., `chat_id`) over display strings.
